It is a monoterpene and a cyclohexadiene. alpha-Terpinene is a natural product found in Xylopia aromatica, Xylopia sericea, and other organisms with data available. One of three isomeric monoterpenes differing in the positions of their two double bonds (beta- and gamma-terpinene being the others). In alpha-terpinene the double bonds are at the 1- and 3-positions of the p-menthane skeleton. Alpha-terpinene, also known as 1-isopropyl-4-methyl-1,3-cyclohexadiene or 1-methyl-4-(1-methylethyl)-1,3-cyclohexadiene, is a member of the class of compounds known as menthane monoterpenoids. Menthane monoterpenoids are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Thus, alpha-terpinene is considered to be an isoprenoid lipid molecule. Alpha-terpinene is a camphoraceous, citrus, and herbal tasting compound and can be found in a number of food items such as summer savory, cabbage, pot marjoram, and wild celery, which makes alpha-terpinene a potential biomarker for the consumption of these food products. Alpha-terpinene can be found primarily in saliva. Alpha-terpinene exists in all eukaryotes, ranging from yeast to humans. α-Terpinene (Terpilene) is a monoterpene found in the essential oils of a large variety of foods and aromatic plants such as Mentha piperita. α-Terpinene is active against Trypanosoma evansi and has the potential for trypanosomosis treatment. α-Terpinene has antioxidant and antifungal properties[1][2][3][4]. α-Terpinene (Terpilene) is a monoterpene found in the essential oils of a large variety of foods and aromatic plants such as Mentha piperita. α-Terpinene is active against Trypanosoma evansi and has the potential for trypanosomosis treatment. α-Terpinene has antioxidant and antifungal properties[1][2][3][4].
Eicosapentaenoic acid
Icosapent, also known as icosapentaenoate or (5z,8z,11z,14z,17z)-eicosapentaenoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, icosapent is considered to be a fatty acid lipid molecule. Icosapent is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Icosapent can be found in a number of food items such as barley, sacred lotus, white lupine, and rape, which makes icosapent a potential biomarker for the consumption of these food products. Icosapent can be found primarily in blood, feces, sweat, and urine, as well as throughout most human tissues. In humans, icosapent is involved in the alpha linolenic acid and linoleic acid metabolism. Moreover, icosapent is found to be associated with essential hypertension and hypertension. Ethyl eicosapentaenoic acid (E-EPA, icosapent ethyl) is a derivative of the omega-3 fatty acid eicosapentaenoic acid (EPA) that is used in combination with changes in diet to lower triglyceride levels in adults with severe (≥ 500 mg/dL) hypertriglyceridemia. This was the second class of fish oil-based drug to be approved for use as a drug and was approved by the FDA in 2012. These fish oil drugs are similar to fish oil dietary supplements but the ingredients are better controlled and have been tested in clinical trials . The anti-inflammatory, antithrombotic and immunomodulatory actions of EPA is probably due to its role in eicosanoid physiology and biochemistry. Most eicosanoids are produced by the metabolism of omega-3 fatty acids, specifically, arachidonic acid. These eicosanoids, leukotriene B4 (LTB4) and thromboxane A2 (TXA2) stimulate leukocyte chemotaxis, platelet aggregation and vasoconstriction. They are thrombogenic and artherogenic. On the other hand, EPA is metabolized to leukotriene B5 (LTB5) and thromboxane A3 (TXA3), which are eicosanoids that promote vasodilation, inhibit platelet aggregation and leukocyte chemotaxis and are anti-artherogenic and anti-thrombotic. The triglyceride-lowering effect of EPA results from inhibition of lipogenesis and stimulation of fatty acid oxidation. Fatty acid oxidation of EPA occurs mainly in the mitochondria. EPA is a substrate for Prostaglandin-endoperoxide synthase 1 and 2. It also appears to affect the function and bind to the Carbohydrate responsive element binding protein (ChREBP) and to a fatty acid receptor (G-coupled receptor) known as GP40 (DrugBank). Eicosapentaenoic acid (EPA or also icosapentaenoic acid) is an important polyunsaturated fatty acid found in fish oils. It serves as the precursor for the prostaglandin-3 and thromboxane-3 families. A diet rich in eicosapentaenoic acid lowers serum lipid concentration, reduces incidence of cardiovascular disorders, prevents platelet aggregation, and inhibits arachidonic acid conversion into the thromboxane-2 and prostaglandin-2 families. Eicosapentaenoic acid is an omega-3 fatty acid. In physiological literature, it is given the name 20:5(n-3). Its systematic chemical name is all-cis-5,8,11,14,17-icosapentaenoic acid. It also has the trivial name timnodonic acid. Chemically, EPA is a carboxylic acid with a 20-carbon chain and five cis double bonds; the first double bond is located at the third carbon from the omega end. Because of the presence of double bonds, EPS is a polyunsaturated fatty acid. Metabolically it acts as a precursor for prostaglandin-3 (which inhibits platelet aggregation), thromboxane-3, and leukotriene-5 groups. It is found in fish oils of cod liver, herring, mackerel, salmon, menhaden, and sardine. It is also found in human breast milk (Wikipedia).

Eicosapentaenoic Acid exhibits a DNA demethylating action that promotes the re-expression of the tumor suppressor gene CCAAT/enhancer-binding protein δ (C/EBPδ). Eicosapentaenoic Acid activates RAS/ERK/C/EBPβ pathway through H-Ras intron 1 CpG island demethylation in U937 leukemia cells. Eicosapentaenoic Acid can promote relaxation of vascular smooth muscle cells and vasodilation[1][2][3].

Sphinganine
Sphinganine, also known as c18-dihydrosphingosine or safingol, is a member of the class of compounds known as 1,2-aminoalcohols. 1,2-aminoalcohols are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Thus, sphinganine is considered to be a sphingoid base lipid molecule. Sphinganine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Sphinganine can be found in a number of food items such as agar, biscuit, herbs and spices, and pasta, which makes sphinganine a potential biomarker for the consumption of these food products. Sphinganine can be found primarily in blood, feces, and urine, as well as throughout most human tissues. Sphinganine exists in all eukaryotes, ranging from yeast to humans. In humans, sphinganine is involved in few metabolic pathways, which include globoid cell leukodystrophy, metachromatic leukodystrophy (MLD), and sphingolipid metabolism. Sphinganine is also involved in few metabolic disorders, which include fabry disease, gaucher disease, and krabbe disease. Moreover, sphinganine is found to be associated with pregnancy. Sphinganine is a lyso-sphingolipid protein kinase inhibitor. It has the molecular formula C18H39NO2 and is a colorless solid. Medicinally, safingol has demonstrated promising anticancer potential as a modulator of multi-drug resistance and as an inducer of necrosis. The administration of safingol alone has not been shown to exert a significant effect on tumor cell growth. However, preclinical and clinical studies have shown that combining safingol with conventional chemotherapy agents such as fenretinide, vinblastine, irinotecan and mitomycin C can dramatically potentiate their antitumor effects. Currently in Phase I clinical trials, it is believed to be safe to co-administer with cisplatin . Sphinganine belongs to the class of organic compounds known as 1,2-aminoalcohols. These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Thus, sphinganine is considered to be a sphingoid base lipid molecule. Sphinganine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Sphinganine exists in all living species, ranging from bacteria to humans. Within humans, sphinganine participates in a number of enzymatic reactions. In particular, sphinganine can be converted into 3-dehydrosphinganine through its interaction with the enzyme 3-ketodihydrosphingosine reductase. In addition, sphinganine can be converted into sphinganine 1-phosphate; which is catalyzed by the enzyme sphingosine kinase 2. Outside of the human body, sphinganine has been detected, but not quantified in, several different foods, such as Mexican oregano, jostaberries, winter squash, angelica, and epazotes. This could make sphinganine a potential biomarker for the consumption of these foods. Sphinganine blocks postlysosomal cholesterol transport by inhibiting low-density lipoprotein-induced esterification of cholesterol and causing unesterified cholesterol to accumulate in perinuclear vesicles. It has been suggested that endogenous sphinganine may inhibit cholesterol transport in Niemann-Pick Type C (NPC) disease (PMID: 1817037).

Cortisol
Cortisol is the main glucocorticoid secreted by the adrenal cortex and it is involved in the stress response. Its synthetic counterpart hydrocortisone is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions. Hydrocortisone is synthesized from pregnenolone and is used as an immunosuppressive drug given by injection in the treatment of severe allergic reactions such as anaphylaxis and angioedema, in place of prednisolone in patients who need steroid treatment but cannot take oral medication, and peri-operatively in patients on long-term steroid treatment to prevent an Addisonian crisis. Cortisol increases blood pressure, blood sugar levels, may cause infertility in women, and suppresses the immune system. The amount of cortisol present in the serum undergoes diurnal variation, with the highest levels present in the early morning and lower levels in the evening, several hours after the onset of sleep. Cortisol is found to be associated with ACTH deficiency and glucocorticoid deficiency, which are inborn errors of metabolism. Cortisol binds to the cytosolic glucocorticoid receptor. After binding the receptor, the newly formed receptor-ligand complex translocates itself into the cell nucleus where it binds to many glucocorticoid response elements (GRE) in the promoter region of the target genes. The DNA-bound receptor then interacts with basic transcription factors, causing the increase in expression of specific target genes. The anti-inflammatory actions of corticosteroids are thought to involve lipocortins, phospholipase A2 inhibitory proteins which, through inhibition arachidonic acid, control the biosynthesis of prostaglandins and leukotrienes. Specifically, glucocorticoids induce lipocortin-1 (annexin-1) synthesis, which then binds to cell membranes and prevents phospholipase A2 from coming into contact with its substrate arachidonic acid. This leads to diminished eicosanoid production. The cyclooxygenase (both COX-1 and COX-2) expression is also suppressed, potentiating the effect. In other words, the two main products of inflammation, prostaglandins and leukotrienes, are inhibited by the action of glucocorticoids. Glucocorticoids also stimulate the escape of lipocortin-1 into the extracellular space, where it binds to the leukocyte membrane receptors and inhibits various inflammatory events: epithelial adhesion, emigration, chemotaxis, phagocytosis, respiratory burst, and the release of various inflammatory mediators (lysosomal enzymes, cytokines, tissue plasminogen activator, chemokines, etc.) from neutrophils, macrophages, and mastocytes. Additionally, the immune system is suppressed by corticosteroids due to a decrease in the function of the lymphatic system, a reduction in immunoglobulin and complement concentrations, the precipitation of lymphocytopenia, and interference with antigen-antibody binding. Cortisol is a steroid hormone, in the glucocorticoid class of hormones and a stress hormone. When used as a medication, it is known as hydrocortisone. It is produced in many animals, mainly by the zona fasciculata of the adrenal cortex in the adrenal gland.[1] It is produced in other tissues in lower quantities.[2] It is released with a diurnal cycle and its release is increased in response to stress and low blood-glucose concentration.[1] It functions to increase blood sugar through gluconeogenesis, to suppress the immune system, and to aid in the metabolism of fat, protein, and carbohydrates.[3] It also decreases bone formation.[4] Many of these functions are carried out by cortisol binding to glucocorticoid or mineralocorticoid receptors inside the cell, which then bind to DNA to affect gene expression.[1][5] Hydrocortisone (Cortisol) is a steroid hormone or glucocorticoid secreted by the adrenal cortex[1].
Phosphoethanolamine
O-Phosphoethanolamine, also known as PEA, phosphorylethanolamine, colamine phosphoric acid or ethanolamine O-phosphate, belongs to the class of organic compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. O-Phosphoethanolamine is used in the biosynthesis of two different types of phospholipids: glycerophospholipids and sphingolipids. O-Phosphoethanolamine exists in all living species, ranging from bacteria to plants to humans. Within humans, O-phosphoethanolamine participates in a number of enzymatic reactions. In particular, cytidine triphosphate and O-phosphoethanolamine can be converted into CDP-ethanolamine; which is mediated by the enzyme ethanolamine-phosphate cytidylyltransferase. In addition, O-phosphoethanolamine can be biosynthesized from ethanolamine; which is catalyzed by the enzyme choline/ethanolamine kinase. In humans, O-phosphoethanolamine is involved in phosphatidylcholine biosynthesis. O-phosphoethanolamine is also a product of the metabolism of sphingolipids. In particular, sphinglipids are metabolized in vivo to phosphorylethanolamine and a fatty aldehyde, generally palmitaldehyde. Both metabolites are ultimately converted to glycerophospholipids. The lipids are first phosphorylated by a kinase and then cleaved by the pyridoxal-dependent sphinganine-1-phosphate aldolase. Elevated urine levels of O-Phosphoethanolamine or PEA can be used to help in the diagnosis of Hypophosphatasia (HPP). Reference ranges for urinary PEA vary according to age and somewhat by diet, and follow a circadian rhythm. Outside of the human body, O-phosphoethanolamine has been detected, but not quantified in, several different foods, such as oxheart cabbages, anises, shiitakes, abalones, and teffs. Phosphoryl-ethanolamine, also known as colamine phosphoric acid or ethanolamine phosphate, is a member of the class of compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. Phosphoryl-ethanolamine is soluble (in water) and a moderately acidic compound (based on its pKa). Phosphoryl-ethanolamine can be found in a number of food items such as pepper (capsicum), black salsify, cascade huckleberry, and redcurrant, which makes phosphoryl-ethanolamine a potential biomarker for the consumption of these food products. Phosphoryl-ethanolamine can be found primarily in most biofluids, including cerebrospinal fluid (CSF), blood, saliva, and feces. Phosphoryl-ethanolamine exists in all living species, ranging from bacteria to humans. In humans, phosphoryl-ethanolamine is involved in several metabolic pathways, some of which include phosphatidylethanolamine biosynthesis PE(22:5(4Z,7Z,10Z,13Z,16Z)/22:5(4Z,7Z,10Z,13Z,16Z)), phosphatidylethanolamine biosynthesis PE(14:0/20:1(11Z)), phosphatidylethanolamine biosynthesis PE(20:2(11Z,14Z)/20:3(8Z,11Z,14Z)), and phosphatidylethanolamine biosynthesis PE(22:5(7Z,10Z,13Z,16Z,19Z)/16:1(9Z)). Phosphoryl-ethanolamine is also involved in few metabolic disorders, which include fabry disease, gaucher disease, and krabbe disease. Moreover, phosphoryl-ethanolamine is found to be associated with traumatic brain injury. Acquisition and generation of the data is financially supported in part by CREST/JST.

Arachidonic acid
Arachidonic acid is a polyunsaturated, essential fatty acid that has a 20-carbon chain as a backbone and four cis-double bonds at the C5, C8, C11, and C14 positions. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is synthesized from dietary linoleic acid. Arachidonic acid mediates inflammation and the functioning of several organs and systems either directly or upon its conversion into eicosanoids. Arachidonic acid in cell membrane phospholipids is the substrate for the synthesis of a range of biologically active compounds (eicosanoids) including prostaglandins, thromboxanes, and leukotrienes. These compounds can act as mediators in their own right and can also act as regulators of other processes, such as platelet aggregation, blood clotting, smooth muscle contraction, leukocyte chemotaxis, inflammatory cytokine production, and immune function. Arachidonic acid can be metabolized by cytochrome p450 (CYP450) enzymes into 5,6-, 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acids (EETs), their corresponding dihydroxyeicosatrienoic acids (DHETs), and 20-hydroxyeicosatetraenoic acid (20-HETE). The production of kidney CYP450 arachidonic acid metabolites is altered in diabetes, pregnancy, hepatorenal syndrome, and in various models of hypertension, and it is likely that changes in this system contribute to the abnormalities in renal function that are associated with many of these conditions. Phospholipase A2 (PLA2) catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid (PMID: 12736897, 12736897, 12700820, 12570747, 12432908). The beneficial effects of omega-3 fatty acids are believed to be due in part to selective alteration of arachidonate metabolism that involves cyclooxygenase (COX) enzymes (PMID: 23371504). 9-Oxononanoic acid (9-ONA), one of the major products of peroxidized fatty acids, was found to stimulate the activity of phospholipase A2 (PLA2), the key enzyme to initiate the arachidonate cascade and eicosanoid production (PMID: 23704812). Arachidonate lipoxygenase (ALOX) enzymes metabolize arachidonic acid to generate potent inflammatory mediators and play an important role in inflammation-associated diseases (PMID: 23404351).

Oleamide is an amide of the fatty acid oleic acid. It is an endogenous substance: it occurs naturally in the body of animals. It accumulates in the cerebrospinal fluid during sleep deprivation and induces sleep in animals. It is being studied as a potential medical treatment for mood and sleep disorders, and cannabinoid-regulated depression.

Citral
Geranial, also known as 3,7-dimethyl-2,6-octadienal, citral or lemonal, belongs to the class of organic compounds known as acyclic monoterpenoids. These are monoterpenes that do not contain a cycle. Thus, citral is considered to be an isoprenoid lipid. Two different isomers of 3,7-dimethyl-2,6-octadienal exist. The E-isomer or trans-isomer is known as geranial or citral A. The Z-isomer or cis-isomer is known as neral or citral B. 3,7-dimethyl-2,6-octadienal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral.

Citral has also been reported to be found in Cannabis sativa (PMID:6991645 , 26657499 ). Citral has a strong lemon (citrus) odor. Nerals lemon odor is less intense, but sweeter. Citral is therefore an aroma compound used in perfumery for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. It has strong antimicrobial qualities (PMID:28974979 ) and pheromonal effects in nematodes and insects (PMID:26973536 ). Citral is used in the synthesis of vitamin A, lycopene, ionone, and methylionone (a compound used to mask the smell of smoke).

Dihomolinoleate (20:2n6)
Eicosadienoic acid is an omega-6 fatty acid found in human milk (PMID: 15256803). Omega-6 fatty acids are a family of unsaturated fatty acids which have in common a carbon-carbon double bond in the n−6 position; that is, the sixth bond from the end of the fatty acid. The biological effects of the omega−6 fatty acids are largely mediated by their conversion to n-6 eicosanoids that bind to diverse receptors found in every tissue of the body. Eicosadienoic acid has been identified in the human placenta (PMID: 32033212). Isolated from lipids of Ginkgo biloba (ginkgo) Eicosadienoic acid is a rare, naturally occurring n-6 polyunsaturated fatty acid found mainly in animal tissues[1][2].

Prostaglandin F2alpha
Prostaglandin F2a (PGF2) is one of the earliest discovered and most common prostaglandins. It is actively biosynthesized in various organs of mammals and exhibits a variety of biological activities, including contraction of pulmonary arteries. It is used in medicine to induce labor and as an abortifacient. PGF2a binds to the Prostaglandin F2 receptor (PTGFR) which is a member of the G-protein coupled receptor family. PGF2-alpha mediates luteolysis. Luteolysis is the structural and functional degradation of the corpus luteum (CL) that occurs at the end of the luteal phase of both the estrous and menstrual cycles in the absence of pregnancy. PGF2 may also be involved in modulating intraocular pressure and smooth muscle contraction in the uterus and gastrointestinal tract sphincters. PGF2 is mainly synthesized directly from PGH2 by PGH2 9,11-endoperoxide reductase. A small amount of PGF2 is also produced from PGE2 by PGE2 9-ketoreductase. A PGF2 epimer has been reported to exhibit various biological activities, and its levels are increased in bronchoalveolar lavage fluid, plasma, and urine in patients with mastocytosis and bronchial asthma. PGF2 is synthesized from PGD2 by PGD2 11-ketoreductase. (PMID: 16475787). Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways.

Dehydroepiandrosterone sulfate
Dehydroepiandrosterone sulfate or DHEA-S is the sulfated form of dehydroepiandrosterone (DHEA). This sulfation is reversibly catalyzed by sulfotransferase 2A1 (SULT2A1) primarily in the adrenals, the liver, and small intestine. In the blood, most DHEA is found as DHEA-S with levels that are about 300 times higher than those of free DHEA. Orally-ingested DHEA is converted into its sulfate when passing through the intestines and liver. Whereas DHEA levels naturally reach their peak in the early morning hours, DHEAS levels show no diurnal variation. From a practical point of view, measurement of DHEA-S is preferable to DHEA since levels are more stable. DHEA (from which DHEA-S comes from) is a natural steroid prohormone produced from cholesterol by the adrenal glands, the gonads, adipose tissue, brain, and in the skin (by an autocrine mechanism). DHEA is the precursor of androstenedione, which can undergo further conversion to produce the androgen testosterone and the estrogens estrone and estradiol. DHEA is also a potent sigma-1 agonist. Serum dehydroepiandrosterone sulfate is a classic marker for adrenarche, and subsequently for the individual hormonal milieu (PMID: 10599744). Dehydroepiandrosterone sulfate is an endogenously produced sex steroid that has been hypothesized to have anti-aging effects (PMID: 16960027). It also has been inversely associated with the development of atherosclerosis (PMID: 8956025). DHEAS or Dehydroepiandrosterone sulfate is the sulfated form of DHEA.

Sugar acids and derivatives are compounds containing a saccharide unit which bears a carboxylic acid group. 3PG is the conjugate acid of glycerate 3-phosphate (GP or G3P). It is a solid that is soluble in water. 3-Phosphoglyceric acid exists in all living species, ranging from bacteria to humans. The glycerate is a biochemically significant metabolic intermediate in both glycolysis and the Calvin cycle. This is the first compound formed during the C3 or Calvin cycle. Glycerate 3-phosphate is also a precursor for serine, which, in turn, can create cysteine and glycine through the homocysteine cycle. Within humans, 3-phosphoglyceric acid participates in a number of enzymatic reactions. In particular, 3-phosphoglyceric acid can be biosynthesized from glyceric acid 1,3-biphosphate, which is mediated by the enzyme phosphoglycerate kinase 1. In addition, 3PG can be converted into 2-phospho-D-glyceric acid, which is catalyzed by the enzyme phosphoglycerate mutase 2. 3-phosphoglyceric acid is involved in the Warburg effect (aerobic glycolysis), a metabolic shift that is a hallmark of cancer (PMID: 29362480). 3-phosphoglyceric acid (3PG) is a 3-carbon molecule that is a metabolic intermediate in both glycolysis and the Calvin cycle. This chemical is often termed PGA when referring to the Calvin cycle. In the Calvin cycle, two glycerate 3-phosphate molecules are reduced to form two molecules of glyceraldehyde 3-phosphate (GALP).

(+)-Limonene
(+)-Limonene, also known as d-limonene, is a naturally occurring monoterpene which is the major component in orange oil. Currently, (+)-limonene is widely used as a flavour and fragrance and is listed to be generally recognized as safe in food by the Food and Drug Administration (21 CFR 182.60 in the Code of Federal Regulations, U.S.A.). Recently, however, (+)-limonene has been shown to cause a male rat-specific kidney toxicity referred to as hyaline droplet nephropathy. Furthermore, chronic exposure to (+)-limonene causes a significant incidence of renal tubular tumours exclusively in male rats. Although (+)-limonene is not carcinogenic in female rats or male and female mice given much higher dosages, the male rat-specific nephrocarcinogenicity of (+)-limonene may raise some concern regarding the safety of (+)-limonene for human consumption. A considerable body of scientific data has indicated that the renal toxicity of (+)-limonene results from the accumulation of a protein, alpha 2u-globulin, in male rat kidney proximal tubule lysosomes. This protein is synthesized exclusively by adult male rats. Other species, including humans, synthesize proteins that share significant homology with alpha 2u-globulin. However, none of these proteins, including the mouse equivalent of alpha 2u-globulin, can produce this toxicity, indicating a unique specificity for alpha 2u-globulin. With chronic exposure to (+)-limonene, the hyaline droplet nephropathy progresses and the kidney shows tubular cell necrosis, granular cast formation at the corticomedullary junction, and compensatory cell proliferation. Both (+)-limonene and cis-d-limonene-1,2-oxide (the major metabolite involved in this toxicity) are negative in vitro mutagenicity screens. Therefore, the toxicity-related renal cell proliferation is believed to be integrally involved in the carcinogenicity of (+)-limonene as persistent elevations in renal cell proliferation may increase fixation of spontaneously altered DNA or serve to promote spontaneously initiated cells. The scientific data demonstrates that the tumorigenic activity of (+)-limonene in male rats is not relevant to humans. The three major lines of evidence supporting the human safety of (+)-limonene are (1) the male rat specificity of the nephrotoxicity and carcinogenicity; (2) the pivotal role that alpha 2u-globulin plays in the toxicity, as evidenced by the complete lack of toxicity in other species despite the presence of structurally similar proteins; and (3) the lack of genotoxicity of both (+)-limonene and d-limonene-1,2-oxide, supporting the concept of a nongenotoxic mechanism, namely, sustained renal cell proliferation (PMID:2024047). (4r)-limonene, also known as (+)-4-isopropenyl-1-methylcyclohexene or (R)-1-methyl-4-(1-methylethenyl)cyclohexene, is a member of the class of compounds known as menthane monoterpenoids.

Dihydrocarveol is a herbal, menthol, and minty tasting compound and can be found in a number of food items such as dill, pot marjoram, pepper (spice), and caraway, which makes dihydrocarveol a potential biomarker for the consumption of these food products.
Pinene
Pinene (is a bicyclic monoterpene chemical compound. There are two structural isomers of pinene found in nature: alpha-pinene and beta-pinene. As the name suggests, both forms are important constituents of pine resin; they are also found in the resins of many other conifers, as well as in non-coniferous plants. Both isomers are used by many insects in their chemical communication system.

MG(18:1(9Z)/0:0/0:0)
MG(18:1(9Z)/0:0/0:0) is a monoacylglyceride. A monoglyceride, more correctly known as a monoacylglycerol, is a glyceride consisting of one fatty acid chain covalently bonded to a glycerol molecule through an ester linkage. Monoacylglycerol can be broadly divided into two groups; 1-monoacylglycerols (or 3-monoacylglycerols) and 2-monoacylglycerols, depending on the position of the ester bond on the glycerol moiety. Normally the 1-/3-isomers are not distinguished from each other and are termed alpha-monoacylglycerols, while the 2-isomers are beta-monoacylglycerols. Monoacylglycerols are formed biochemically via release of a fatty acid from diacylglycerol by diacylglycerol lipase or hormone sensitive lipase. Monoacylglycerols are broken down by monoacylglycerol lipase. They tend to be minor components only of most plant and animal tissues, and indeed would not be expected to accumulate because their strong detergent properties would have a disruptive effect on membranes. 2-Monoacylglycerols are a major end product of the intestinal digestion of dietary fats in animals via the enzyme pancreatic lipase. They are taken up directly by the intestinal cells and converted to triacylglycerols via the monoacylglycerol pathway before being transported in lymph to the liver. Mono- and Diglycerides are commonly added to commercial food products in small quantities. They act as emulsifiers, helping to mix ingredients such as oil and water that would not otherwise blend well. MG(18:1(9Z)/0:0/0:0) belongs to the family of monoradyglycerols, which are glycerolipids lipids containing a common glycerol backbone to which at one fatty acyl group is attached. Their general formula is [R1]OCC(CO[R2])O[R3]. MG(18:1(9Z)/0:0/0:0) is made up of one 9Z-octadecenoyl(R1). Monoolein is an endogenous metabolite. Monoolein is an endogenous metabolite.
Tetranor 12-HETE
12(S)-HETE is a product of arachidonic acid metabolism through the 12-lipoxygenase pathway. It is primarily found in platelets, leukocytes, and to a lesser extent in smooth muscle cells. It enhances tumor cell adhesion to endothelial cells, fibronectin, and the subendothelial matrix. tetranor-12(S)-HETE is the major β-oxidation product resulting from peroxisomal metabolism of 12(S)-HETE in numerous tissues, and Lewis lung carcinoma cells. No biological function has yet been determined for tetranor-12(S)-HETE. Some data indicate it may play a role in controlling the inflammatory response in injured corneas.4 In some diseases (e.g., Zellweger’s Syndrome) peroxisomal abnormalities result in the inability of cells to metabolize 12(S)-HETE, which may be responsible for symptoms of the disease. The tetranor derivative of 12(S)-HETE is available as a research tool for the elucidation of the metabolic fate of its parent compound. (http://www.caymanchem.com)
Hypogeic acid
7z-palmitoleic acid, also known as (Z)-7-hexadecenoic acid or 16:1 cis7, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, 7z-palmitoleic acid is considered to be a fatty acid lipid molecule. 7z-palmitoleic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 7z-palmitoleic acid can be found in peanut, which makes 7z-palmitoleic acid a potential biomarker for the consumption of this food product. 7z-palmitoleic acid can be found primarily in blood. Hypogeic acid is a fatty acids found in human milk Approximately 50\\% of the dietary calories in human milk are supplied to new-borns as fat. More than 98\\% of this milk fat is in the form of triglycerides, which contain fatty acid glycerol esters. Fatty acid composition in human milk changes in colostrum, transitional milk and mature milk. Knowledge of fatty acid composition of human milk is of importance for the manufacture of infant formulas, determination of the influence of diet in fatty acid composition of human milk and changes in composition with lactation.

L-Carnitine
Carnitine is a non-essential amino acid and a quaternary ammonium compound. Carnitine is also classified as an alcohol (specifically, a trimethylated carboxy-alcohol). Carnitine exists as one of two stereoisomers (the two enantiomers D-carnitine and L-carnitine. Both are biologically active, but only L-carnitine naturally occurs in animals, and D-carnitine is toxic as it inhibits the activity of the L-form. Carnitine is involved in the metabolism in most mammals, plants, and some bacteria. Carnitine plays a key role in lipid metabolism and beta-oxidation. It is used to transport long-chain fatty acids into the mitochondria to be oxidized for energy production. This is done by forming a long chain acetylcarnitine esters which are then transported by carnitine palmitoyltransferase I and carnitine palmitoyltransferase II. Carnitine also participates in removing products of metabolism from cells. Given its key metabolic roles, carnitine is concentrated in skeletal and cardiac muscle as well as other tissues that metabolize fatty acids as an energy source. A normal 70 kilogram person typically produces 11‚Äì34 mg of carnitine per day. Adults eating mixed diets of red meat and other animal products ingest 60‚Äì180 mg of carnitine per day, while vegans consume about 10‚Äì12 mg per day. Most carnitine obtained from the diet is absorbed in the small intestine before entering the blood.[3] The total body content of carnitine is about 20 grams in a person weighing 70 kilograms, with nearly all of it contained within skeletal muscle cells. Carnitine is so important in providing energy to muscles (including the heart) that some researchers are now recommending carnitine supplements in the diet, particularly for people who do not consume much red meat (the main food source for carnitine). Carnitine has been described as a vitamin, an amino acid, or a metabimin (i.e. an essential metabolite). Like the B vitamins, carnitine contains nitrogen and is very soluble in water. However, most animals, including humans, make their own carnitine; thus, carnitine cannot be considered to be a vitamin. In certain circumstances, such as methionine deficiency, lysine deficiency, vitamin C deficiency or kidney dialysis, carnitine shortages can develop. Under these conditions, carnitine must be absorbed from food, and for this reason, it is sometimes referred to as a "metabimin" or a conditionally essential metabolite. In humans, about 25\\\\% of carnitine is synthesized in the liver, kidney, and brain from lysine and methionine. Most of the carnitine in the body comes from dietary sources such as red meat and dairy products. Inborn errors of carnitine metabolism such as Reye‚Äôs syndrome can lead to brain deterioration gradually worsening muscle weakness, Duchenne-like muscular dystrophy, and extreme muscle weakness with fat accumulation in muscles. Carnitine is an essential nutrient for pre-term babies and individuals who are unable to eat a normal diet (e.g. non-ketotic hypoglycemics, kidney dialysis patients) (PMID: 115309). In conditions such as kwashiorkor, cirrhosis, and heart muscle disease (cardiomyopathy) as well as in inborn errors of metabolism such as type IV hyperlipidemia and propionic aciduria, carnitine is essential to life and carnitine supplements are critically important. Carnitine therapy may also be useful in a wide variety of clinical conditions. Carnitine supplementation has improved some patients who have angina secondary to coronary artery disease. Carnitine supplements may also be useful in many forms of metabolic liver diseases and heart muscle disease. Hearts undergoing severe arrhythmia quickly deplete their stores of carnitine. Athletes, particularly in Europe, have used carnitine supplements for improved endurance. Carnitine may improve muscle building by improving fat utilization and may even be useful in treating obesity. Carnitine may be of value in treating pregnant women, hypothyroid individuals, and male infertility due to t... Malonyl-carnitin, also known as d,l-carnitine or carnitine chloride, is a member of the class of compounds known as carnitines.

Glycerophosphocholine
Glycerophosphorylcholine (GPC) is a choline derivative and one of the two major forms of choline storage (along with phosphocholine) in the cytosol. Glycerophosphorylcholine is also one of the four major organic osmolytes in renal medullary cells, changing their intracellular osmolyte concentration in parallel with extracellular tonicity during cellular osmoadaptation. As an osmolyte, Glycerophosphorylcholine counteracts the effects of urea on enzymes and other macromolecules. Kidneys (especially medullar cells), which are exposed under normal physiological conditions to widely fluctuating extracellular solute concentrations, respond to hypertonic stress by accumulating the organic osmolytes glycerophosphorylcholine (GPC), betaine, myo-inositol, sorbitol and free amino acids. Increased intracellular contents of these osmolytes are achieved by a combination of increased uptake (myo-inositol and betaine) and synthesis (sorbitol, GPC), decreased degradation (GPC) and reduced osmolyte release. GPC is formed in the breakdown of phosphatidylcholine (PtC). This pathway is active in many body tissues, including mammary tissue. Choline alfoscerate, also known as glycerophosphocholine or choline glycerophosphate, is a member of the class of compounds known as glycerophosphocholines.

LysoPC (18:1/0:0)
LysoPC(18:1(9Z)) is a lysophospholipid (LyP). It is a monoglycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. Lysophosphatidylcholines can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) position. Fatty acids containing 16, 18 and 20 carbons are the most common. LysoPC(18:19Z)), in particular, consists of one chain of oleic acid at the C-1 position. The oleic acid moiety, an omega-9 fatty acid, is derived from various animal and vegetable sources such as olive oil, acai and grapeseed oil. Lysophosphatidylcholine is found in small amounts in most tissues. It is formed by hydrolysis of phosphatidylcholine by the enzyme phospholipase A2, as part of the de-acylation/re-acylation cycle that controls its overall molecular species composition. It can also be formed inadvertently during extraction of lipids from tissues if the phospholipase is activated by careless handling. In blood plasma significant amounts of lysophosphatidylcholine are formed by a specific enzyme system, lecithin:cholesterol acyltransferase (LCAT), which is secreted from the liver. The enzyme catalyzes the transfer of the fatty acids of position sn-2 of phosphatidylcholine to the free cholesterol in plasma, with formation of cholesterol esters and lysophosphatidylcholine. Lysophospholipids have a role in lipid signaling by acting on lysophospholipid receptors (LPL-R). LPL-Rs are members of the G protein-coupled receptor family of integral membrane proteins. Lysophosphatidylcholines (LPC), also called lysolecithins, are a class of chemical compounds which are derived from phosphatidylcholines. They result from partial hydrolysis of phosphatidylcholines, which removes one of the fatty acid groups. The hydrolysis is generally the result of the enzymatic action of phospholipase A2. LPC is present as a minor phospholipid in the cell membrane (<=3\\%) and in the blood plasma (8-12\\%). Since LPCs are quickly metabolized by lysophosholypase and LPC-acyltransferase, they last only shortly in vivo. [Wikipedia]. Lysolecithin is found in many foods, some of which are cardamom, cucumber, common buckwheat, and rice.
1-linoleoyl-GPC (18:2)

Oleoylcarnitine (C18:1)
Oleoylcarnitine is an acylcarnitine. More specifically, it is an oleic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. Oleoylcarnitine is therefore classified as a long chain AC. As a long-chain acylcarnitine oleoylcarnitine is generally formed through esterification with long-chain fatty acids obtained from the diet. The main function of most long-chain acylcarnitines is to ensure long chain fatty acid transport into the mitochondria (PMID: 22804748). Altered levels of long-chain acylcarnitines can serve as useful markers for inherited disorders of long-chain fatty acid metabolism. In particular oleoylcarnitine is elevated in the blood or plasma of individuals with carnitine palmitoyl transferase 2 deficiency (PMID: 15653102, PMID: 11999976), cardiovascular mortality in incident dialysis patients (PMID: 24308938), schizophrenia (PMID: 31161852), succinic semialdehyde dehydrogenase deficiency (PMID: 32967698), neonatal macrosomia (PMID: 32126138), liver cirrhosis (PMID: 32075591), CPT II deficiency (PMID: 28801073, PMID: 18987586, PMID: 18925671, PMID: 11585077), carnitine/acylcarnitine translocase (CACT) deficiency (PMID: 15057979 ), and ischaemia/reperfusion (PMID: 26936967, PMID: 22607863, PMID: 24468136). Carnitine palmitoyltransferase I (CPT I, EC:2.3.1.21) is involved in the synthesis of long-chain acylcarnitines (more than C12) on the mitochondrial outer membrane. Elevated serum/plasma levels of long-chain acylcarnitines are not only markers for incomplete FA oxidation but also are indicators of altered carbohydrate and lipid metabolism. High serum concentrations of long-chain acylcarnitines in the postprandial or fed state are markers of insulin resistance and arise from insulins inability to inhibit CPT-1-dependent fatty acid metabolism in muscles and the heart (PMID: 19073774). Increased intracellular content of long-chain acylcarnitines is thought to serve as a feedback inhibition mechanism of insulin action (PMID: 23258903). In healthy subjects, increased concentrations of insulin effectively inhibits long-chain acylcarnitine production. Several studies have also found increased levels of circulating long-chain acylcarnitines in chronic heart failure patients (PMID: 26796394). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].

Tetradecanoylcarnitine, also known as myristoylcarnitine, is a member of the class of compounds known as acylcarnitines. Acylcarnitines are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond. Acylcarnitines are useful in the diagnosis of genetic disorders such as fatty acid oxidation disorders and differentiation between biochemical phenotypes of medium-chain acyl-CoA dehydrogenase (MCAD) deficiency disorders (PMID: 12385891). Tetradecanoylcarnitine is involved in the beta-oxidation of long-chain fatty acids (PMID: 16425363). Tetradecanoylcarnitine is found to be associated with glutaric aciduria II, which is an inborn error of metabolism.

LysoPE (16:0/0:0)
LysoPE(16:0/0:0) is a lysophosphatidylethanolamine or a lysophospholipid. The term lysophospholipid (LPL) refers to any phospholipid that is missing one of its two O-acyl chains. Thus, LPLs have a free alcohol in either the sn-1 or sn-2 position.

LysoPC(17:0/0:0)
LysoPC(17:0) is a lysophospholipid (LyP). It is a monoglycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. Lysophosphatidylcholines can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) position. Fatty acids containing 16, 18 and 20 carbons are the most common. LysoPC(17:0), in particular, consists of one chain of margaric acid at the C-1 position. The margaric acid moiety is derived from butter, milk and fat of ruminants. Lysophosphatidylcholine is found in small amounts in most tissues. It is formed by hydrolysis of phosphatidylcholine by the enzyme phospholipase A2, as part of the de-acylation/re-acylation cycle that controls its overall molecular species composition. It can also be formed inadvertently during extraction of lipids from tissues if the phospholipase is activated by careless handling. In blood plasma significant amounts of lysophosphatidylcholine are formed by a specific enzyme system, lecithin:cholesterol acyltransferase (LCAT), which is secreted from the liver. The enzyme catalyzes the transfer of the fatty acids of position sn-2 of phosphatidylcholine to the free cholesterol in plasma, with formation of cholesterol esters and lysophosphatidylcholine.

Pregnenolone sulfate
Pregnenolone sulfate is a sulfated version of the steroid hormone known as pregnenolone. Pregnenolone sulfate belongs to the class of organic compounds known as sulfated steroids. These are sterol lipids containing a sulfate group attached to the steroid skeleton. Pregnenolone sulfate is a neurosteroid found in the brain and central nervous system. Pregnenolone sulfate is a metabolite synthesized from pregnenolone via sulfation. It is known to have cognitive and memory-enhancing, antidepressant, anxiogenic, and proconvulsant effects (PMID: 21094889). As a neurosteroid, pregnenolone sulfate modulates a variety of ion channels, transporters, and enzymes. Interestingly, as a sulfated steroid, pregnenolone sulfate is not the final- or waste-product of pregnenolone being sulfated via a phase II metabolism reaction and renally excreted, as one would presume from pharmacology textbook knowledge. Pregnenolone sulfate is also the source and thereby the starting point for subsequent steroid synthesis pathways. Recently, pregnenolone sulfate has been shown to not only be a modulator of ion channels, but it is also an activating ion channel ligand (PMID: 24084011). Pregnenolone sulfate, a neurosteroid, is a metabolite of Pregnenolone. It is found in the brain and central nervous system.

Hexanoylcarnitine
Hexanoylcarnitine (CAS: 6418-78-6), also known as caproylcarnitine, is an acylcarnitine. Acylcarnitines are the product of the conjugation of carnitine with acyl-coenzyme A, that allows the transport of fatty acids across mitochondrial membranes. Long or medium chain fatty acids are then oxidized in the mitochondria for energy production. The ionic nature of L-carnitine causes high water solubility which decreases with increasing chain lengths of the ester group in the acylcarnitines. Therefore, the distribution of L-carnitine and acylcarnitines in various organs is defined not only by their function but also by their physicochemical properties. Hexanoylcarnitine is a medium-chain acylcarnitine present in the urine of patients with medium-chain acyl-CoA dehydrogenase deficiency (PMID: 1635814). Hexanoylcarnitine is also found to be associated with celiac disease and glutaric aciduria II which are both inborn errors of metabolism. Numerous disorders have been described that lead to disturbances in energy production and in intermediary metabolism, which are characterized by the production and excretion of unusual acylcarnitines. A mutation in the gene coding for carnitine-acylcarnitine translocase or the OCTN2 transporter aetiologically causes a carnitine deficiency that results in poor intestinal absorption of dietary L-carnitine, its impaired reabsorption by the kidney and, consequently, in increased urinary loss of L-carnitine. Determination of the qualitative pattern of acylcarnitines can be of diagnostic and therapeutic importance. The betaine structure of carnitine requires special analytical procedures for recording. High-performance liquid chromatography (HPLC) permits screening for free and total carnitine, as well as complete quantitative acylcarnitine determination, including the long-chain acylcarnitine profile (PMID: 17508264, Monatshefte fuer Chemie (2005), 136(8), 1279-1291., Int J Mass Spectrom. 1999;188:39-52.).

Food flavourant for baked goods and candies (E)-Oct-2-enoic acid is an endogenous metabolite. (E)-Oct-2-enoic acid is an endogenous metabolite.
Tiglylcarnitine
Tiglylcarnitine is an acylcarnitine. More specifically, it is an tiglic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. Tiglylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine Tiglylcarnitine is a member of the most abundant group of carnitines in the body, comprising more than 50\\% of all acylcarnitines quantified in tissues and biofluids (PMID: 31920980). Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. In particular Tiglylcarnitine is elevated in the blood or plasma of individuals with beta ketothiolase deficiency/acat1 gene mutation (PMID: 27264805, PMID: 14518824, PMID: 3435793), and ECHS1 deficiency (PMID: 31908952). It is also decreased in the blood or plasma of individuals with familial mediterranean fever (PMID: 29900937), carcinoma, lewis lung (PMID: 30839735), metabolic syndrome, type 2 diabetes mellitus, and cardiovascular diseases (PMID: 24710945). Tiglylcarnitine is also detected in the urinary organic acid and blood spot acylcarnitine profiles in patients with mitochondrial acetoacetyl-CoA thiolase (T2) deficiency, an inborn error of metabolism affecting isoleucine and ketone bodies in the catabolic process (PMID: 14518824 ). Tiglylcarnitine is found to be associated with celiac disease, which is also an inborn error of metabolism. Tiglylcarnitine has been identified in the human placenta (PMID: 32033212 ). Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews]. Tiglylcarnitine is detected in the urinary organic acid and blood spot acylcarnitine profiles in patients with
Linoleyl carnitine
Linoleyl carnitine is a long-chain acyl fatty acid derivative ester of carnitine. Long-chain acyl fatty acid derivatives accumulate in the cytosol and serum of patients suffering of mitochondrial carnitine palmitoyltransferase II (CPT II, EC 2.3.1.12) deficiency, the most common inherited disorder of lipid metabolism in adults. Carnitine palmitoyltransferase II deficiency is an autosomal recessive disorder of fatty acid metabolism presenting as two clinical phenotypes: (i) a severe infantile hepatocardiomuscular form and (ii) a milder adult muscular form. Energy production from long-chain fatty acids (LCFAs) requires the transport of LCFAs into the mitochondrial matrix. This transport is carnitine-dependent and involves translocation machinery. Mitochondrial fatty acid oxidation disorders cause hypoglycaemia, hepatic dysfunction, myopathy, cardiomyopathy and encephalopathy. Patients with end-stage renal disease (ESRD) undergoing long-term haemodialysis exhibit elevated acylcarnitine concentrations (PMID: 11999976, 10682306, 15025677, 16168195).

LysoPI(18:1(9Z)/0:0)
LysoPI(18:1(9Z)/0:0) is a lysophosphatidylinositol. The term lysophospholipid (LPL) refers to any phospholipid that is missing one of its two O-acyl chains. Thus, LPLs have a free alcohol in either the sn-1 or sn-2 position. The prefix lyso- comes from the fact that lysophospholipids were originally found to be hemolytic. However, it is now used to refer generally to phospholipids missing an acyl chain. LPLs are usually the result of phospholipase A-type enzymatic activity on regular phospholipids such as phosphatidylcholine or phosphatidic acid, although they can also be generated by the acylation of glycerophospholipids or the phosphorylation of monoacylglycerols. Lysophosphatidylinositols can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) or C-2 (sn-2) position. LysoPI(18:1(9Z)/0:0), in particular, consists of one chain of oleic acid at the C-1 position.

Succinyl Carnitine
Succinylcarnitine is an acylcarnitine. More specifically, it is an succinic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. Succinylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine Succinylcarnitine is a member of the most abundant group of carnitines in the body, comprising more than 50\\% of all acylcarnitines quantified in tissues and biofluids (PMID: 31920980), it has been identified in the human placenta (PMID: 32033212 ). Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].
Epiandrosterone sulfate
Epiandrosterone sulfate, also known as (3beta,5alpha)-17-oxoandrostan-3-yl hydrogen sulfate or epiandrosterone sulphuric acid, is a member of the class of compounds known as sulfated steroids. Sulfated steroids are sterol lipids containing a sulfate group attached to the steroid skeleton. Epiandrosterone sulfate is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). Epiandrosterone sulfate can be synthesized from 5alpha-androstane and synthesized into epiandrosterone. Epiandrosterone sulfate can be found in blood and feces.

LPLs are usually the result of phospholipase A-type enzymatic activity on regular phospholipids such as phosphatidylcholine or phosphatidic acid, although they can also be generated by the acylation of glycerophospholipids or the phosphorylation of monoacylglycerols. Lysophosphatidylcholine is found in small amounts in most tissues. It is formed by hydrolysis of phosphatidylcholine by the enzyme phospholipase A2 as part of the de-acylation/re-acylation cycle that controls its overall molecular species composition. It can also be formed inadvertently during extraction of lipids from tissues if the phospholipase is activated by careless handling. There is also a phospholipase A1, which is able to cleave the sn-1 ester bond. Lysophosphatidylcholine has pro-inflammatory properties in vitro and it is known to be a pathological component of oxidized lipoproteins (LDL) in plasma and of atherosclerotic lesions. Recently, it has been found to have some functions in cell signalling, and specific receptors (coupled to G proteins) have been identified. It activates the specific phospholipase C that releases diacylglycerols and inositol triphosphate with resultant increases in intracellular Ca2+ and activation of protein kinase C. It also activates the mitogen-activated protein kinase in certain cell types. Lysophosphatidylcholines can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) or C-2 (sn-2) position.

Palmitoylcarnitine
L-Palmitoylcarnitine or hexadecanoylcarnitine is an acylcarnitine. It is technically a long-chain acyl fatty acid derivative ester of carnitine which facilitates the transfer of long-chain fatty acids from cytoplasm into mitochondria during the oxidation of fatty acids. The general role of acylcarnitines is to transport acyl-groups, organic acids and fatty acids, from the cytoplasm into the mitochondria so that they can be broken down to produce energy. As part of this process, palmitic acid is first transported into the cell via the long-chain fatty acid transport protein 1 (FATP1). Once inside the cell it undergoes a reaction to form an acyl-CoA derivative called palmitoyl-CoA. This reaction is facilitated by the Long-chain fatty-acid CoA ligase 1 protein, which adds a CoA moiety to appropriate acyl groups. Many acyl-CoA groups will then further react with other zwitterionic compounds such as carnitine (to form acylcarnitines) and amino acids (to form acyl amides). The carnitine needed to form acylcarnitines inside the cell is transported into the cell by the organic cation/carnitine transporter 2. In forming an acylcarnitine derivative, palmitoyl-CoA reacts with L-carnitine to form palmitoylcarnitine. This reaction is catalyzed by carnitine O-palmitoyltransferase. This enzyme resides in the mitochondrial outer membrane. While this reaction takes place, the palmitoylcarnitine is moved into the mitochondrial intermembrane space. Following the reaction, the newly synthesized acylcarnitine is transported into the mitochondrial matrix by a mitochondrial carnitine/acylcarnitine carrier protein found in the mitochondrial inner membrane. Once in the matrix, palmitoylcarnitine can react with the carnitine O-palmitoyltransferase 2 enzyme found in the mitochondrial inner membrane to once again form palmitoyl-CoA and L-carnitine. Palmitoyl-CoA then enters into the mitochondrial beta-oxidation pathway to form aceytl-CoA. Acetyl-CoA can go on to enter the TCA cycle, or it can react with L-carnitine to form L-acetylcarnitine in a reaction catalyzed by Carnitine O-acetyltransferase. This reaction can occur in both directions, and L-acetylcarnitine and CoA can react to form acetyl-CoA and L-carnitine in certain circumstances. Finally, acetyl-CoA in the cytosol can be catalyzed by acetyl-CoA carboxylase 1 to form malonyl-CoA, which inhibits the action of carnitine O-palmitoyltransferase 1, thereby preventing palmitoylcarnitine from forming and thereby preventing it from being transported into the mitochondria. L-Palmitoylcarnitine has been also reported to change the activity of certain proteins and to stimulate the activity of caspases 3, 7, and 8. Interestingly, the level of this long-chain acylcarnitine has been shown to increase during apoptosis. Palmitoylcarnitine has also been reported to diminish the binding of phorbol esters (protein kinase C activators) and the autophosphorylation of the enzyme. Some of the physicochemical properties of palmitoylcarnitine may help to explain the need for coenzyme A-carnitine-coenzyme A acyl exchange during mitochondrial fatty acid import. The amphiphilic character of palmitoylcarnitine may also explain its proposed involvement in the pathogenesis of myocardial ischemia. L-Palmitoylcarnitine accumulates in ischemic myocardium and potentially contributes to myocardial damage through alterations in membrane molecular dynamics. This is a mechanism through which could play an important role in ischemic injury (PMID: 2540838, 15363641, 8706815). Palmitoylcarnitine is characteristically elevated in late-onset carnitine palmitoyltransferase II deficiency (OMIM: 255110). L-Palmitoylcarnitine is a long-chain acyl fatty acid derivative ester of carnitine which facilitates the transfer of long-chain fatty acids from cytoplasm into mitochondria during the oxidation of fatty acids. L-palmitoylcarnitine, due to its amphipatic character is, like detergents, a surface-active molecule and by changing the membrane fluidity and surface charge can change activity of several enzymes and transporters localized in the membrane. L-palmitoylcarnitine has been also reported to change the activity of certain proteins. On the contrary to carnitine, palmitoylcarnitine was shown to stimulate the activity of caspases 3, 7 and 8 and the level of this long-chain acylcarnitine increased during apoptosis. Palmitoylcarnitine was also reported to diminish completely binding of phorbol esters, the protein kinase C activators and to decrease the autophosphorylation of the enzyme. Apart from these isoform nonspecific phenomena, palmitoylcarnitine was also shown to be responsible for retardation in cytoplasm of protein kinase C isoforms β and δ and, in the case of the latter one, to decrease its interaction with GAP-43.

1-linoleoyl-GPC (18:2)
LysoPC(18:2(9Z,12Z)) is a lysophospholipid (LyP). It is a monoglycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. Lysophosphatidylcholines can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) position. Fatty acids containing 16, 18 and 20 carbons are the most common. LysoPC(18:2(9Z,12Z)), in particular, consists of one chain of linoleic acid at the C-1 position. The linoleic acid moiety is derived from seed oils. Lysophosphatidylcholine is found in small amounts in most tissues. It is formed by hydrolysis of phosphatidylcholine by the enzyme phospholipase A2, as part of the de-acylation/re-acylation cycle that controls its overall molecular species composition. It can also be formed inadvertently during extraction of lipids from tissues if the phospholipase is activated by careless handling. In blood plasma significant amounts of lysophosphatidylcholine are formed by a specific enzyme system, lecithin:cholesterol acyltransferase (LCAT), which is secreted from the liver. The enzyme catalyzes the transfer of the fatty acids of position sn-2 of phosphatidylcholine to the free cholesterol in plasma, with formation of cholesterol esters and lysophosphatidylcholine. Lysophospholipids have a role in lipid signaling by acting on lysophospholipid receptors (LPL-R). LPL-Rs are members of the G protein-coupled receptor family of integral membrane proteins. Lysopc(18:2(9z,12z)), also known as lysophosphatidylcholine(18:2/0:0) or lpc(18:2n6/0:0), is a member of the class of compounds known as 1-acyl-sn-glycero-3-phosphocholines. 1-acyl-sn-glycero-3-phosphocholines are glycerophosphocholines in which the glycerol is esterified with a fatty acid at O-1 position, and linked at position 3 to a phosphocholine. Thus, lysopc(18:2(9z,12z)) is considered to be a glycerophosphocholine lipid molecule. Lysopc(18:2(9z,12z)) is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Lysopc(18:2(9z,12z)) can be found in a number of food items such as japanese persimmon, jicama, rubus (blackberry, raspberry), and chinese bayberry, which makes lysopc(18:2(9z,12z)) a potential biomarker for the consumption of these food products.
