Carnitine
(R)-carnitine is the (R)-enantiomer of carnitine. It has a role as an antilipemic drug, a water-soluble vitamin (role), a nutraceutical, a nootropic agent and a Saccharomyces cerevisiae metabolite. It is a conjugate base of a (R)-carnitinium. It is an enantiomer of a (S)-carnitine. Constituent of striated muscle and liver. It is used therapeutically to stimulate gastric and pancreatic secretions and in the treatment of hyperlipoproteinemias. L-Carnitine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Levocarnitine is a Carnitine Analog. Levocarnitine is a natural product found in Mucidula mucida, Pseudo-nitzschia multistriata, and other organisms with data available. Levocarnitine is an amino acid derivative. Levocarnitine facilitates long-chain fatty acid entry into mitochondria, delivering substrate for oxidation and subsequent energy production. Fatty acids are utilized as an energy substrate in all tissues except the brain. (NCI04) Carnitine is not an essential amino acid; it can be synthesized in the body. However, it 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, and to some researchers carnitine is a vitamin (Liebovitz 1984). It was found that an animal (yellow mealworm) could not grow without carnitine in its diet. However, as it turned out, almost all other animals, including humans, do make their own carnitine; thus, it is no longer considered a vitamin. Nevertheless, in certain circumstances-such as deficiencies of methionine, lysine or vitamin C or kidney dialysis--carnitine shortages 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. Like the other amino acids used or manufactured by the body, carnitine is an amine. But like choline, which is sometimes considered to be a B vitamin, carnitine is also an alcohol (specifically, a trimethylated carboxy-alcohol). Thus, carnitine is an unusual amino acid and has different functions than most other amino acids, which are most usually employed by the body in the construction of protein. Carnitine is an essential factor in fatty acid metabolism in mammals. Its most important known metabolic function is to transport fat into the mitochondria of muscle cells, including those in the heart, for oxidation. This is how the heart gets most of its energy. In humans, about 25\\\\\% of carnitine is synthesized in the liver, kidney and brain from the amino acids 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 can lead to brain deterioration like that of Reyes syndrome, gradually worsening muscle weakness, Duchenne-like muscular dystrophy and extreme muscle weakness with fat accumulation in muscles. Borurn et al. (1979) describe carnitine as an essential nutrient for pre-term babies, certain types (non-ketotic) of hypoglycemics, kidney dialysis patients, cirrhosis, and in kwashiorkor, type IV hyperlipidemia, heart muscle disease (cardiomyopathy), and propionic or organic aciduria (acid urine resulting from genetic or other anomalies). In all these conditions and the inborn errors of carnitine metabolism, carnitine is essential to life and carnitine supplements are valuable. 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. It may be worth a trial in any form of hyperlipidemia or muscle weakness. carnitine supplements may... (-)-Carnitine. CAS Common Chemistry.

Citric acid
Citric acid (citrate) is a tricarboxylic acid, an organic acid with three carboxylate groups. Citrate is an intermediate in the TCA cycle (also known as the Tricarboxylic Acid cycle, the Citric Acid cycle or Krebs cycle). The TCA cycle is a central metabolic pathway for all animals, plants, and bacteria. As a result, citrate is found in all living organisms, from bacteria to plants to animals. In the TCA cycle, the enzyme citrate synthase catalyzes the condensation of oxaloacetate with acetyl CoA to form citrate. Citrate then acts as the substrate for the enzyme known as aconitase and is then converted into aconitic acid. The TCA cycle ends with regeneration of oxaloacetate. This series of chemical reactions in the TCA cycle is the source of two-thirds of the food-derived energy in higher organisms. Citrate can be transported out of the mitochondria and into the cytoplasm, then broken down into acetyl-CoA for fatty acid synthesis, and into oxaloacetate. Citrate is a positive modulator of this conversion, and allosterically regulates the enzyme acetyl-CoA carboxylase, which is the regulating enzyme in the conversion of acetyl-CoA into malonyl-CoA (the commitment step in fatty acid synthesis). In short, citrate is transported into the cytoplasm, converted into acetyl CoA, which is then converted into malonyl CoA by acetyl CoA carboxylase, which is allosterically modulated by citrate. In mammals and other vertebrates, Citrate is a vital component of bone, helping to regulate the size of apatite crystals (PMID: 21127269). Citric acid is found in citrus fruits, most concentrated in lemons and limes, where it can comprise as much as 8\\\\\% of the dry weight of the fruit. Citric acid is a natural preservative and is also used to add an acidic (sour) taste to foods and carbonated drinks. Because it is one of the stronger edible acids, the dominant use of citric acid is as a flavoring and preservative in food and beverages, especially soft drinks and candies. Citric acid is an excellent chelating agent, binding metals by making them soluble. It is used to remove and discourage the buildup of limescale from boilers and evaporators. It can be used to treat water, which makes it useful in improving the effectiveness of soaps and laundry detergents. The salts of citric acid (citrates) can be used as anticoagulants due to their calcium chelating ability. Intolerance to citric acid in the diet is known to exist. Little information is available as the condition appears to be rare, but like other types of food intolerance it is often described as a "pseudo-allergic" reaction. Citric acid appears as colorless, odorless crystals with an acid taste. Denser than water. (USCG, 1999) Citric acid is a tricarboxylic acid that is propane-1,2,3-tricarboxylic acid bearing a hydroxy substituent at position 2. It is an important metabolite in the pathway of all aerobic organisms. It has a role as a food acidity regulator, a chelator, an antimicrobial agent and a fundamental metabolite. It is a conjugate acid of a citrate(1-) and a citrate anion. A key intermediate in metabolism. It is an acid compound found in citrus fruits. The salts of citric acid (citrates) can be used as anticoagulants due to their calcium-chelating ability. Citric acid is one of the active ingredients in Phexxi, a non-hormonal contraceptive agent that was approved by the FDA on May 2020. It is also used in combination with magnesium oxide to form magnesium citrate, an osmotic laxative. Citric acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Anhydrous citric acid is a Calculi Dissolution Agent and Anti-coagulant. The mechanism of action of anhydrous citric acid is as an Acidifying Activity and Calcium Chelating Activity. The physiologic effect of anhydrous citric acid is by means of Decreased Coagulation Factor Activity. Anhydrous Citric Acid is a tricarboxylic acid found in citrus fruits. Citric acid is used as an excipient in pharmaceutical preparations due to its antioxidant properties. It maintains stability of active ingredients and is used as a preservative. It is also used as an acidulant to control pH and acts as an anticoagulant by chelating calcium in blood. A key intermediate in metabolism. It is an acid compound found in citrus fruits. The salts of citric acid (citrates) can be used as anticoagulants due to their calcium chelating ability. See also: Citric Acid Monohydrate (related). Citrate, also known as anhydrous citric acid or 2-hydroxy-1,2,3-propanetricarboxylic acid, belongs to tricarboxylic acids and derivatives class of compounds. Those are carboxylic acids containing exactly three carboxyl groups. Citrate is soluble (in water) and a weakly acidic compound (based on its pKa). Citrate can be found in a number of food items such as ucuhuba, loquat, bayberry, and longan, which makes citrate a potential biomarker for the consumption of these food products. Citrate can be found primarily in most biofluids, including saliva, sweat, feces, and blood, as well as throughout all human tissues. Citrate exists in all living species, ranging from bacteria to humans. In humans, citrate is involved in several metabolic pathways, some of which include the oncogenic action of succinate, the oncogenic action of fumarate, the oncogenic action of 2-hydroxyglutarate, and congenital lactic acidosis. Citrate is also involved in several metabolic disorders, some of which include 2-ketoglutarate dehydrogenase complex deficiency, pyruvate dehydrogenase deficiency (E2), fumarase deficiency, and glutaminolysis and cancer. Moreover, citrate is found to be associated with lung Cancer, tyrosinemia I, maple syrup urine disease, and propionic acidemia. A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solution. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. When part of a salt, the formula of the citrate ion is written as C6H5O73− or C3H5O(COO)33− .

Palmitic acid
Palmitic acid, also known as palmitate or hexadecanoic 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, palmitic acid is considered to be a fatty acid lipid molecule. Palmitic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Palmitic acid can be found in a number of food items such as sacred lotus, spinach, shallot, and corn salad, which makes palmitic acid a potential biomarker for the consumption of these food products. Palmitic acid can be found primarily in most biofluids, including feces, sweat, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Palmitic acid exists in all living species, ranging from bacteria to humans. In humans, palmitic acid is involved in several metabolic pathways, some of which include alendronate action pathway, rosuvastatin action pathway, simvastatin action pathway, and cerivastatin action pathway. Palmitic acid is also involved in several metabolic disorders, some of which include hypercholesterolemia, familial lipoprotein lipase deficiency, ethylmalonic encephalopathy, and carnitine palmitoyl transferase deficiency (I). Moreover, palmitic acid is found to be associated with schizophrenia. Palmitic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and dairy products. Palmitate is the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4) . Palmitic acid is the first fatty acid produced during lipogenesis (fatty acid synthesis) and from which longer fatty acids can be produced. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC) which is responsible for converting acetyl-ACP to malonyl-ACP on the growing acyl chain, thus preventing further palmitate generation (DrugBank). Palmitic acid, or hexadecanoic acid, is one of the most common saturated fatty acids found in animals, plants, and microorganisms. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Excess carbohydrates in the body are converted to palmitic acid. Palmitic acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids. As a consequence, palmitic acid is a major body component of animals. In humans, one analysis found it to make up 21–30\\\% (molar) of human depot fat (PMID: 13756126), and it is a major, but highly variable, lipid component of human breast milk (PMID: 352132). Palmitic acid is used to produce soaps, cosmetics, and industrial mould release agents. These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate. Aluminium salts of palmitic acid and naphthenic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid (Wikipedia). Palmitic acid is also used in the determination of water hardness and is a surfactant of Levovist, an intravenous ultrasonic contrast agent. Hexadecanoic acid is a straight-chain, sixteen-carbon, saturated long-chain fatty acid. It has a role as an EC 1.1.1.189 (prostaglandin-E2 9-reductase) inhibitor, a plant metabolite, a Daphnia magna metabolite and an algal metabolite. It is a long-chain fatty acid and a straight-chain saturated fatty acid. It is a conjugate acid of a hexadecanoate. A common saturated fatty acid found in fats and waxes including olive oil, palm oil, and body lipids. Palmitic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Palmitic Acid is a saturated long-chain fatty acid with a 16-carbon backbone. Palmitic acid is found naturally in palm oil and palm kernel oil, as well as in butter, cheese, milk and meat. Palmitic acid, or hexadecanoic acid is one of the most common saturated fatty acids found in animals and plants, a saturated fatty acid found in fats and waxes including olive oil, palm oil, and body lipids. It occurs in the form of esters (glycerides) in oils and fats of vegetable and animal origin and is usually obtained from palm oil, which is widely distributed in plants. Palmitic acid is used in determination of water hardness and is an active ingredient of *Levovist*TM, used in echo enhancement in sonographic Doppler B-mode imaging and as an ultrasound contrast medium.

Maltotetraose
Maltotetraose belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Maltotetraose exists in all living organisms, ranging from bacteria to humans. Outside of the human body, maltotetraose has been detected, but not quantified in several different foods, such as welsh onions, kales, small-leaf lindens, other bread, and romaine lettuces. Maltotetraose is a normal human oligo saccharide present in plasma, but is elevated in cases of Pompe disease (PMID 15886040). Alpha-D-Glcp-(1->4)-alpha-D-Glcp-(1->4)-alpha-D-Glcp-(1->4)-D-Glcp is a maltotetraose tetrasaccharide consisting of three alpha-D-glucopyranose residues and a D-glucopyranose residue joined in sequence by (1->4) glycosidic bonds. Amylotetraose is a natural product found in Streptomyces with data available. Constituent of corn syrup. Product of action of a-amylase on starch.

Maltotetraose can be used as a substrate for the enzyme-coupled determination of amylase activity in biological fluids.
Cholestenone
Cholestenone belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, cholestenone is considered to be a sterol lipid molecule. Cholestenone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Cholestenone is a dehydrocholestanone. It is a product of cholesterol oxidase {EC 1.1.3.6] in the Bile acid biosynthesis pathway (KEGG). [HMDB] Cholestenone (4-Cholesten-3-one), the intermediate oxidation product of cholesterol, is metabolized primarily in the liver. Cholestenone is highly mobile in membranes and influences cholesterol flip-flop and efflux. Cholestenone may cause long-term functional defects in cells[1][2].

Crotonoyl-CoA
Crotonoyl-CoA is an important component in several metabolic pathways, notably fatty acid and amino acid metabolism. It is the substrate of a group of enzymes acyl-Coenzyme A oxidases 1, 2, 3 (E.C.: 1.3.3.6) corresponding to palmitoyl, branched chain, and pristanoyl, respectively, in the peroxisomal fatty acid beta-oxidation, producing hydrogen peroxide. Abnormality of this group of enzymes is linked to coma, dehydration, diabetes, fatty liver, hyperinsulinemia, hyperlipidemia, and leukodystrophy. It is also a substrate of a group of enzymes called acyl-Coenzyme A dehydrogenase (E.C.:1.3.99-, including 1.3.99.2, 1.3.99.3) in the metabolism of fatty acids or branched chain amino acids in the mitochondria (Rozen et al., 1994). Acyl-Coenzyme A dehydrogenase (1.3.99.3) has shown to contribute to kidney-associated diseases, such as adrenogential syndrome, kidney failure, kidney tubular necrosis, homocystinuria, as well as other diseases including cretinism, encephalopathy, hypoglycemia, medium chain acyl-CoA dehydrogenase deficiency. The gene (ACADS) also plays a role in theta oscillation during sleep. In addition, crotonoyl-CoA is the substrate of enoyl coenzyme A hydratase (E.C.4.2.1.17) in the mitochondria during lysine degradation and tryptophan metabolism, benzoate degradation via CoA ligation; in contrast it is the product of this enzyme in the butanoate metabolism. Moreover, it is produced from multiple enzymes in the butanoate metabolism pathway, including 3-Hydroxybutyryl-CoA dehydratase (E.C.:4.2.1.55), glutaconyl-CoA decarboxylase (E.C.: 4.1.1.70), vinylacetyl-CoA Δ-isomerase (E.C.: 5.3.3.3), and trans-2-enoyl-CoA reductase (NAD+) (E.C.: 1.3.1.44). In lysine degradation and tryptophan metabolism, crotonoyl CoA is produced by glutaryl-Coenzyme A dehydrogenase (E.C.:1.3.99.7) lysine and tryptophan metabolic pathway. This enzyme is linked to type-1glutaric aciduria, metabolic diseases, movement disorders, myelinopathy, and nervous system diseases.

In lysine degradation and tryptophan metabolism, crotonoyl-CoA is produced by glutaryl-coenzyme A dehydrogenase (EC 1.3.99.7). This enzyme is linked to glutaric aciduria type I, metabolic diseases, movement disorders, myelinopathy, and nervous system diseases.
Pipecolic acid
Pipecolic acid is a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF. However, it is uncertain if pipecolic acid originates directly from food intake or from mammalian or intestinal bacterial enzyme metabolism. Recent studies suggest that plasma pipecolic acid, particularly the D-isomer, originates mainly from the catabolism of dietary lysine by intestinal bacteria rather than by direct food intake. In classic Zellweger syndrome (a cerebro-hepato-renal genetic disorder, OMIM 214100) pipecolic acid accumulate in the plasma of the patients. It is known that plasma pipecolic acid levels are also elevated in patients with chronic liver diseases. Pipecolic acid is moderately elevated in patients with pyridoxine-dependent seizures and might therefore be a possible biochemical marker for selecting candidates for pyridoxine therapy (Plecko et al 2000). Pipecolic acid was also elevated in CSF in these vitamin B6-responsive patients (PMID 12705501). Pipecolic acid is found to be associated with adrenoleukodystrophy, infantile Refsum disease, and peroxisomal biogenesis defect, which are also inborn errors of metabolism. Pipecolic acid is a biomarker for the consumption of dried and cooked beans. Pipecolic acid is a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF.

Adipic acid
Adipic acid is an important inudstrial dicarboxylic acid with about 2.5 billion kilograms produced per year. It is used mainly in the production of nylon. It occurs relatively rarely in nature. It has a tart taste and is also used as an additive and gelling agent in jello or gelatins. It is also used in some calcium carbonate antacids to make them tart. Adipic acid has also been incorporated into controlled-release formulation matrix tablets to obtain pH-independent release for both weakly basic and weakly acidic drugs. Adipic acid in the urine and in the blood is typically exogenous in origin and is a good biomarker of jello consumption. In fact, a condition known as adipic aciduria is actually an artifact of jello consumption (PMID: 1779643). However, certain disorders (such as diabetes and glutaric aciduria type I.) can lead to elevated levels of adipic acid snd other dicarboxcylic acids (such as suberic acid) in urine (PMID: 17520433; PMID: 6778884). Moreover, adipic acid is also found to be associated with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, carnitine-acylcarnitine translocase deficiency, malonyl-Coa decarboxylase deficiency, and medium Chain acyl-CoA dehydrogenase deficiency, which are inborn errors of metabolism. Adipic acid is also microbial metabolite found in Escherichia. Constituent of beet juice, pork fat, guava fruit (Psidium guajava), papaya (Carica papaya) and raspberry (Rubus idaeus).

Phenylpyruvate
Phenylpyruvic acid is a keto-acid that is an intermediate or catabolic byproduct of phenylalanine metabolism. It has a slight honey-like odor. Levels of phenylpyruvate are normally very low in blood or urine. High levels of phenylpyruvic acid can be found in the urine of individuals with phenylketonuria (PKU), an inborn error of metabolism. PKU is due to lack of the enzyme phenylalanine hydroxylase (PAH), so that phenylalanine is converted not to tyrosine but to phenylpyruvic acid. In particular, excessive phenylalanine can be metabolized into phenylketones through, a transaminase pathway route involving glutamate. Metabolites of this transamination reaction include phenylacetate, phenylpyruvate and phenethylamine. In persons with PKU, dietary phenylalanine either accumulates in the body or some of it is converted to phenylpyruvic acid. Individuals with PKU tend to excrete large quantities of phenylpyruvate, phenylacetate and phenyllactate, along with phenylalanine, in their urine. If untreated, mental retardation effects and microcephaly are evident by the first year along with other symptoms which include: unusual irritability, epileptic seizures and skin lesions. Hyperactivity, EEG abnormalities and seizures, and severe learning disabilities are major clinical problems later in life. A "musty or mousy" odor of skin, hair, sweat and urine (due to phenylacetate accumulation); and a tendency to hypopigmentation and eczema are also observed. The neural-development effects of PKU are primarily due to the disruption of neurotransmitter synthesis. In particular, phenylalanine is a large, neutral amino acid which moves across the blood-brain barrier (BBB) via the large neutral amino acid transporter (LNAAT). Excessive phenylalanine in the blood saturates the transporter. Thus, excessive levels of phenylalanine significantly decrease the levels of other LNAAs in the brain. But since these amino acids are required for protein and neurotransmitter synthesis, phenylalanine accumulation disrupts brain development, leading to mental retardation. Phenylpyruvic acid is also a microbial metabolite, it can be produced by Lactobacillus plantarum (PMID: 9687465). Flavouring ingredient Phenylpyruvic acid is used in the synthesis of 3-phenyllactic acid (PLA) by lactate dehydrogenase[1]. Phenylpyruvic acid is used in the synthesis of 3-phenyllactic acid (PLA) by lactate dehydrogenase[1].
alpha-D-Glucose 1,6-bisphosphate
Glucose 1,6-diphosphate (G-1,6-P2) is considered to be a major regulator of carbohydrate metabolism. It has been demonstrated that G-1,6-P2 is a potent activator (deinhibitor) of skeletal muscle phosphofructokinase (PFK) and phosphoglucomutase, while being an inhibitor of hexokinase (see Ref. 2). In addition, G-1,6-P2 has been shown to inhibit 6-phosphogluconate dehydrogenase in various rat tissues and fructose 1,6-bisphosphatase in bovine liver. Various factors and conditions affect the tissue content of G-1,6-P2. Specifically, anoxia induces a rapid fall in the content of G-l,6-P2 in the brain. Glucose 1,6-diphosphate has been recognized as a regulatory signal implicated in the control of metabolism, oxygen affinity of red cells, and other cellular functions. The levels of G 1,6-P2 are reduced in the liver and in the muscle of rats with experimentally induced diabetes. In muscle of genetically dystrophic mice, a decrease in the levels of G 1,6-P2 has been found, probably resulting from enhancement of glucose 1,6-P2 phosphatase activity. G 1,6-P2 is an inhibitor of hexokinase and its level is increased significantly after 5 min of exercise (~25\\%) and then decreased continuously. G 1,6-P2 is a potent allosteric activator of phosphofructokinase, and is markedly decreased in muscles of patients with glycogenosis type VII (muscle phosphofructokinase deficiency) and type V (muscle phosphorylase deficiency). Chronic alcohol intake produces an increase in the concentration of G 1,6-P2 in human muscle before the first sign of myopathy appears. When myopathy is present the level decreases to be similar to healthy humans. These changes could contribute to the decline in skeletal muscle performance (PMID:1449560, 2018547, 2003594, 3407759). Glucose 1,6-diphosphate is considered to be a major regulator of carbohydrate metabolism.

Clofibrate
Clofibrate is only found in individuals that have used or taken this drug. It is a fibric acid derivative used in the treatment of hyperlipoproteinemia type III and severe hypertriglyceridemia (from Martindale, The Extra Pharmacopoeia, 30th ed, p986). Clofibrate increases the activity of extrahepatic lipoprotein lipase (LL), thereby increasing lipoprotein triglyceride lipolysis. Chylomicrons are degraded, VLDLs are converted to LDLs, and LDLs are converted to HDL. This is accompanied by a slight increase in secretion of lipids into the bile and ultimately the intestine. Clofibrate also inhibits the synthesis and increases the clearance of apolipoprotein B, a carrier molecule for VLDL. Also, as a fibrate, clofibrate is an agonist of the PPAR-α receptor[4] in muscle, liver, and other tissues. This agonism ultimately leads to modification in gene expression resulting in increased beta-oxidation, decreased triglyceride secretion, increased HDL, increased lipoprotein lipase activity.

Diazoxide
Diazoxide is only found in individuals that have used or taken this drug. It is a benzothiadiazine derivative that is a peripheral vasodilator used for hypertensive emergencies. It lacks diuretic effect, apparently because it lacks a sulfonamide group. [PubChem]As a diuretic, diazoxide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like diazoxide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of diazoxide is less well understood although it may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle. As a antihypoglycemic, diazoxide inhibits insulin release from the pancreas, probably by opening potassium channels in the beta cell membrane.

Phosphocreatine
Phosphocreatine, also known as creatine phosphate (CP) or PCr (Pcr), is a phosphorylated creatine molecule that serves as a rapidly mobilizable reserve of high-energy phosphates in skeletal muscle, myocardium and the brain to recycle adenosine triphosphate, the energy currency of the cell. Phosphocreatine undergoes irreversible cyclization and dehydration to form creatinine at a fractional rate of 0.026 per day, thus forming approximately 2 g creatinine/day in an adult male. This is the amount of creatine that must be provided either from dietary sources or by endogenous synthesis to maintain the body pool of (creatine and) phosphocreatine. Creatine is an amino acid that plays a vital role as phosphocreatine in regenerating adenosine triphosphate in skeletal muscle to energize muscle contraction. Creatine is phosphorylated to phosphocreatine in muscle in a reaction that is catalyzed by the enzyme creatine kinase. This enzyme is in highest concentration in muscle and nerve. Oral administration increases muscle stores. During the past decade, creatine has assumed prominence as an ergogenic (and legal) aid for professional and elite athletes. Most (~ 95\\%) of the total body creatine-phosphocreatine pool is in muscle (more in skeletal muscle than in smooth muscle) and amounts to 120 g (or 925 mmol) in a 70 kg adult male. Approximately 60-67\\% of the content in resting muscle is in the phosphorylated form. This generates enough ATP at the myofibrillar apparatus to power about 4 seconds of muscle contraction in exercise. Phosphocreatine reacts with ADP to yield ATP and creatine; the reversible reaction is catalyzed by creatine kinase. phosphocreatine is the chief store of high-energy phosphates in muscle. Thus, this reaction, which permits the rephosphorylation of ADP to ATP, is the immediate source of energy in muscle contraction. During rest, metabolic processes regenerate phosphocreatine stores. In normal muscle, ATP that is broken down to ADP is immediately rephosphorylated to ATP. Thus, phosphocreatine serves as a reservoir of ATP-synthesizing potential. phosphocreatine is the only fuel available to precipitously regenerate ATP during episodes of rapid fluctuations in demand. The availability of phosphocreatine likely limits muscle performance during brief, high-power exercise, i.e., maximal exercise of short duration. With near maximal isometric contraction, the rate of utilization of phosphocreatine declines after 1-2 seconds of contraction, prior to the glycolysis peak at approximately 3 seconds (PMID:10079702). Phosphocreatine undergoes irreversible cyclization and dehydration to form creatinine at a fractional rate of 0.026 per day, thus forming approximately 2 g creatinine/day in an adult male.

N2-acetyllysine
N-alpha-Acetyl-L-lysine also known as Nalpha-Acetyllysine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-alpha-Acetyl-L-lysine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-alpha-Acetyl-L-lysine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lysine. Unlike L-lysine, acetylated lysine derivatives such as N-alpha-Acetyl-L-lysine are zwitterionic compounds. These are molecules that contains an equal number of positively- and negatively-charged functional groups. N-alpha-Acetyl-L-lysine is found naturally in eukaryotes ranging from yeast to plants to humans. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\% of all human proteins and 68\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-alpha-Acetyl-L-lysine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free lysine can also occur. In particular, N-alpha-Acetyl-L-lysine can be biosynthesized from L-lysine and acetyl-CoA via the enzyme known as Lysine N-acetyltransferase. Individuals with hyperlysinaemia due to L-lysine alpha-ketoglutarate reductase deficiency will excrete high levels of N-alpha-Acetyl-L-lysine in their urine (PMID: 116084). L-lysine alpha-ketoglutarate reductase deficiency, if untreated, can lead to neurological and behavioral deficits (PMID: 116084). Many N-acetylamino acids are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). Acetyl-L-lysine is an endogenous metabolite.

Vaccenic acid
Vaccenic acid is a naturally occurring trans fatty acid. It is the predominant kind of trans-fatty acid found in human milk, in the fat of ruminants, and in dairy products such as milk, butter, and yogurt. Trans fat in human milk may depend on trans fat content in food. Its IUPAC name is (11E)-11-octadecenoic acid, and its lipid shorthand name is 18:1 trans-11. The name was derived from the Latin vacca (cow). Vaccenic acid belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Vaccenic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Occurs in small proportions in ruminant fats (e.g., butter) via biohydrogenation of dietary polyene acids. Vaccenic acid is found in many foods, some of which are almond, romaine lettuce, butter, and pak choy. trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated linoleic acid (CLA) at the tissue level. trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated linoleic acid (CLA) at the tissue level.

Propionyl-CoA
Propionyl-CoA is an intermediate in the metabolism of propanoate. Propionic aciduria is caused by an autosomal recessive disorder of propionyl coenzyme A (CoA) carboxylase deficiency (EC 6.4.1.3). In propionic aciduria, propionyl CoA accumulates within the mitochondria in massive quantities; free carnitine is then esterified, creating propionyl carnitine, which is then excreted in the urine. Because the supply of carnitine in the diet and from synthesis is limited, such patients readily develop carnitine deficiency as a result of the increased loss of acylcarnitine derivatives. This condition demands supplementation of free carnitine above the normal dietary intake to continue to remove (detoxify) the accumulating organic acids. Propionyl-CoA is a substrate for Acyl-CoA dehydrogenase (medium-chain specific, mitochondrial), Acetyl-coenzyme A synthetase 2-like (mitochondrial), Propionyl-CoA carboxylase alpha chain (mitochondrial), Methylmalonate-semialdehyde dehydrogenase (mitochondrial), Trifunctional enzyme beta subunit (mitochondrial), 3-ketoacyl-CoA thiolase (peroxisomal), Acyl-CoA dehydrogenase (long-chain specific, mitochondrial), Malonyl-CoA decarboxylase (mitochondrial), Acetyl-coenzyme A synthetase (cytoplasmic), 3-ketoacyl-CoA thiolase (mitochondrial) and Propionyl-CoA carboxylase beta chain (mitochondrial).

Phytanate
Phytanic acid (or 3,7,11,15-tetramethylhexadecanoic acid) is a 20-carbon branched-chain fatty acid that humans can obtain through the consumption of dairy products, ruminant animal fats, and certain fish. It is primarily formed by bacterial degradation of chlorophyll in the intestinal tract of ruminants. Unlike most fatty acids, phytanic acid cannot be metabolized by beta-oxidation (because of a methyl group in the beta position). Instead, it undergoes alpha-oxidation in the peroxisome, where it is converted into pristanic acid by the removal of one carbon. Pristanic acid can undergo several rounds of beta-oxidation in the peroxisome to form medium-chain fatty acids that can be converted into carbon dioxide and water in mitochondria. Refsum disease, an autosomal recessive neurological disorder caused by mutations in the PHYH gene, is characterized by having impaired alpha-oxidation activity. Individuals with Refsum disease accumulate large stores of phytanic acid in their blood and tissues. This frequently leads to peripheral polyneuropathy, cerebellar ataxia, retinitis pigmentosa, anosmia, and hearing loss. Therefore, chronically high levels of phytanic acid can be neurotoxic. Phytanic acids neurotoxicity appears to lie in its ability to initiate astrocyte/neural cell death by activating the mitochondrial route of apoptosis. In particular, phytanic acid can induce the substantial generation of reactive oxygen species in isolated mitochondria as well as in intact cells. It also induces the release of cytochrome c from mitochondria. A 20-carbon branched chain fatty acid, Phytanic acid is present in animal (primarily herbivores or omnivores) tissues where it may be derived from the chlorophyll in consumed plant material. Phytanic acid derives from the corresponding alcohol, phytol, and is ultimately oxidized into pristanic acid. In phytanic acid storage disease (Refsum disease) this lipid may comprise as much as 30\\% of the total fatty acids in plasma. These high levels in Refsum disease (a neurological disorder) are due to a phytanic acid alpha-hydroxylase deficiency.; A 20-carbon branched chain fatty acid. In phytanic acid storage disease (Refsum disease) this lipid may comprise as much as 30\\% of the total fatty acids of the plasma. This is due to a phytanic acid alpha-hydroxylase deficiency. [HMDB]
Tiglyl-CoA
Tiglyl-CoA is a metabolite in the degradation of isoleucine to propionic acid pathway. A defect in the conversion of tiglyl-CoA to alpha-methyl-beta-hydroxybutyryl-CoA, results in episodic abdominal pain and acidosis in patients with Tiglic acidemia (OMIM 275190). Tiglyl-CoA is a metabolite in the degradation of isoleucine to propionic acid pathway.
2-Methyl-3-hydroxybutyryl-CoA
2-Methyl-3-hydroxybutyryl-CoA (CAS: 6701-38-8) belongs to the class of organic compounds known as (S)-3-hydroxyacyl-CoAs. These are organic compounds containing an (S)-3-hydroxyl acylated coenzyme A derivative. Thus, 2-methyl-3-hydroxybutyryl-CoA is considered to be a fatty ester lipid molecule. 2-Methyl-3-hydroxybutyryl-CoA is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 2-Methyl-3-hydroxybutyryl-CoA is a substrate for 3-hydroxyacyl-CoA dehydrogenase type II, enoyl-CoA hydratase, trifunctional enzyme alpha subunit, short-chain 3-hydroxyacyl-CoA dehydrogenase, and peroxisomal bifunctional enzyme. 2-Methyl-3-hydroxybutyryl-CoA is a substrate for 3-hydroxyacyl-CoA dehydrogenase type II, Enoyl-CoA hydratase (mitochondrial), Trifunctional enzyme alpha subunit (mitochondrial), Short chain 3-hydroxyacyl-CoA dehydrogenase (mitochondrial) and Peroxisomal bifunctional enzyme.

Imidazole-4-acetaldehyde
Imidazole-4-acetaldehyde is a naturally occurring aldehyde metabolite of histamine formed by the action of histaminase (E.C. 1.4.3.6), and can be synthesized by oxidation of histidine. Aldehyde dehydrogenase (EC 1.2.1.3) is the only enzyme in the human liver capable of catalyzing dehydrogenation of aldehydes arising via monoamine, diamine, and plasma amine oxidases. NAD-linked dehydrogenation of short chain aliphatic aldehydes has been found in virtually every organ of the mammalian body. Imidazole-4-acetaldehyde is a good substrate for all aldehyde dehydrogenase isozymes. Experimentally, the prebiotic formation of histidine has been accomplished by the reaction of erythrose with formamidine followed by a Strecker synthesis. Imidazole-4-acetaldehyde could have been converted to histidine on the primitive earth by a Strecker synthesis, and several prebiotic reactions could convert imidazole-4-glycol and imidazole-4-ethanol to imidazole-4-acetaldehyde. (PMID: 2071588, 2957640, 11536478). Imidazole-4-acetaldehyde is a member of the class of compounds known as imidazoles. Imidazoles are compounds containing an imidazole ring, which is an aromatic five-member ring with two nitrogen atoms at positions 1 and 3, and three carbon atoms. Imidazole-4-acetaldehyde is soluble (in water) and a very weakly acidic compound (based on its pKa). Imidazole-4-acetaldehyde can be found in a number of food items such as wild celery, alaska wild rhubarb, orange bell pepper, and common beet, which makes imidazole-4-acetaldehyde a potential biomarker for the consumption of these food products. In humans, imidazole-4-acetaldehyde is involved in the histidine metabolism. Imidazole-4-acetaldehyde is also involved in histidinemia, which is a metabolic disorder.

(S)-Hydroxydecanoyl-CoA
(s)-hydroxydecanoyl-coa, also known as S-(3-hydroxydecanoate) CoA or 3S-hydroxy-decanoyl-CoA is an acyl-CoA or acyl-coenzyme A. More specifically, it is a 3-hydroxydecanoic acid thioester of coenzyme A. (s)-hydroxydecanoyl-coa is an acyl-CoA with 10 fatty acid group as the acyl moiety attached to coenzyme A. Coenzyme A was discovered in 1946 by Fritz Lipmann (Journal of Biological Chemistry (1946) 162 (3): 743–744) and its structure was determined in the early 1950s at the Lister Institute in London. Coenzyme A is a complex, thiol-containing molecule that is naturally synthesized from pantothenate (vitamin B5), which is found in various foods such as meat, vegetables, cereal grains, legumes, eggs, and milk. More specifically, coenzyme A (CoASH or CoA) consists of a beta-mercaptoethylamine group linked to the vitamin pantothenic acid (B5) through an amide linkage and 3-phosphorylated ADP. Coenzyme A is synthesized in a five-step process that requires four molecules of ATP, pantothenate and cysteine. It is believed that there are more than 1100 types of acyl-CoA’s in the human body, which also corresponds to the number of acylcarnitines in the human body. Acyl-CoAs exists in all living species, ranging from bacteria to plants to humans. The general role of acyl-CoA’s is to assist in transferring fatty acids from the cytoplasm to mitochondria. This process facilitates the production of fatty acids in cells, which are essential in cell membrane structure. Acyl-CoAs are also susceptible to beta oxidation, forming, ultimately, acetyl-CoA. Acetyl-CoA can enter the citric acid cycle, eventually forming several equivalents of ATP. In this way, fats are converted to ATP -- or biochemical energy. Acyl-CoAs can be classified into 9 different categories depending on the size of their acyl-group: 1) short-chain acyl-CoAs; 2) medium-chain acyl-CoAs; 3) long-chain acyl-CoAs; and 4) very long-chain acyl-CoAs; 5) hydroxy acyl-CoAs; 6) branched chain acyl-CoAs; 7) unsaturated acyl-CoAs; 8) dicarboxylic acyl-CoAs and 9) miscellaneous acyl-CoAs. Short-chain acyl-CoAs have acyl-groups with two to four carbons (C2-C4), medium-chain acyl-CoAs have acyl-groups with five to eleven carbons (C5-C11), long-chain acyl-CoAs have acyl-groups with twelve to twenty carbons (C12-C20) while very long-chain acyl-CoAs have acyl groups with more than 20 carbons. (s)-hydroxydecanoyl-coa is therefore classified as a medium chain acyl-CoA. The oxidative degradation of fatty acids is a two-step process, catalyzed by acyl-CoA synthetase/synthase. Fatty acids are first converted to their acyl phosphate, the precursor to acyl-CoA. The latter conversion is mediated by acyl-CoA synthase. Three types of acyl-CoA synthases are employed, depending on the chain length of the fatty acid. (s)-hydroxydecanoyl-coa, being a medium chain acyl-CoA is a substrate for medium chain acyl-CoA synthase. The second step of fatty acid degradation is beta oxidation. Beta oxidation occurs in mitochondria and, in the case of very long chain acyl-CoAs, the peroxisome. After its formation in the cytosol, (S)-Hydroxydecanoyl-CoA is transported into the mitochondria, the locus of beta oxidation. Transport of (S)-Hydroxydecanoyl-CoA into the mitochondria requires carnitine palmitoyltransferase 1 (CPT1), which converts (S)-Hydroxydecanoyl-CoA into 3-Hydroxydecanoylcarnitine, which gets transported into the mitochondrial matrix. Once in the matrix, 3-Hydroxydecanoylcarnitine is converted back to (S)-Hydroxydecanoyl-CoA by CPT2, whereupon beta-oxidation can begin. Beta oxidation of (S)-Hydroxydecanoyl-CoA occurs in four steps. First, since (S)-Hydroxydecanoyl-CoA is a medium chain acyl-CoA it is the substrate for a medium chain acyl-CoA dehydrogenase, which catalyzes dehydrogenation of (S)-Hydroxydecanoyl-CoA, creating a double bond between the alpha and beta carbons. FAD is the hydrogen acceptor, yielding FADH2. Second, Enoyl-CoA hydrase catalyzes the addition of water across the newly formed double bo... (S)-Hydroxydecanoyl-CoA has a role in the synthesis and oxidation of fatty acids. It is involved in fatty acid elongation in mitochondria. In this pathway 3-Oxodecanoyl-CoA is acted upon by two enzymes, 3-hydroxyacyl-CoA dehydrogenase and long-chain-3-hydroxyacyl-CoA dehydrogenase to produce (S)-Hydroxydecanoyl-CoA. Since coenzyme A is chemically a thiol, it can react with carboxylic acids to form thioesters, thus functioning as an acyl group carrier. It assists in transferring fatty acids from the cytoplasm to mitochondria. A molecule of coenzyme A carrying an acetyl group is also referred to as acetyl-CoA. When it is not attached to an acyl group it is usually referred to as CoASH or HSCoA. [HMDB]
3-Oxohexanoyl-CoA
3-Oxohexanoyl-CoA is an intermediate in Fatty acid elongation in mitochondria. 3-Oxohexanoyl-CoA is the 3rd to last step in the synthesis of Hexanoyl-CoA and is converted from Butanoyl-CoA via the enzyme acetyl-CoA acyltransferase 2 (EC 2.3.1.16). It is then converted to (S)-Hydroxyhexanoyl-CoA via the 3-hydroxyacyl-CoA dehydrogenase (EC 1.1.1.35). [HMDB]. 3-Oxohexanoyl-CoA is found in many foods, some of which are soy bean, cloudberry, other bread, and lemon thyme. 3-Oxohexanoyl-CoA is an intermediate in Fatty acid elongation in mitochondria. 3-Oxohexanoyl-CoA is the 3rd to last step in the synthesis of Hexanoyl-CoA and is converted from Butanoyl-CoA via the enzyme acetyl-CoA acyltransferase 2 (EC 2.3.1.16).

3D,7D,11D-Phytanic acid
3D,7D,11D-Phytanic acid is an isomer of Phytanic acid, an unusual 20-carbon branched-chain fatty acid; Phytanic acid accumulates in blood and tissues of patients with Refsum disease (RD, an inborn error of lipid metabolism inherited as an autosomal recessive trait (OMIM 266500)), and is a reliable identifier of RD from a large number of other neurological disorders.

L-Pipecolic acid
L-pipecolic acid is a normal human metabolite present in human blood, where is present as the primary enantiomer of pipecolic acid. L-pipecolic acid is a cyclic imino acid (contains both imino (>C=NH) and carboxyl (-C(=O)-OH) functional groups) produced during the degradation of lysine, accumulates in body fluids of infants with generalized genetic peroxisomal disorders, including Zellweger syndrome (OMIM 214100), neonatal adrenoleukodystrophy (OMIM 202370), and infantile Refsum disease (OMIM 266510). L-pipecolic acid levels are also elevated in patients with chronic liver diseases. L-pipecolic acid is the substrate of delta1-piperideine-2-carboxylate reductase (EC 1.5.1.21) in the pathway of lysine degradation (PMID: 2717271, 8305590, 1050990). Present in beans and other legumes, and in lesser quantities in other plants including barley, hops, malt and mushrooms. L-Pipecolic acid is found in many foods, some of which are macadamia nut (m. tetraphylla), linden, tinda, and cumin.

Pipecolic acid, a metabolite of Lysine, is an important precursor of many useful microbial secondary metabolites. Pipecolic acid can be used as a diagnostic marker of Pyridoxine-dependent epilepsy[1][2].
O-Palmitoylcarnitine
O-Palmitoylcarnitine is an acylcarnitine. More specifically, it is an palmitic 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. O-Palmitoylcarnitine is therefore classified as a long chain AC. As a long-chain acylcarnitine O-Palmitoylcarnitine 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 O-Palmitoylcarnitine is elevated in the blood or plasma of individuals with very long chain acyl-CoA dehydrogenase (VLCAD) deficiency (PMID: 9034211), sleep deprivation (PMID: 31419538), carnitine palmitoyl transferase 2 deficiency (PMID: 15653102), carnitine-acylcarnitine translocase deficiency (PMID: 12403251), type 2 diabetes mellitus (PMID: 27694567, PMID: 24837145, PMID: 20111019), non-alcoholic fatty liver disease (PMID: 27211699), obesity (PMID: 20111019), pulmonary arterial hypertension (PMID: 27006481), chronic heart failure (PMID: 22622056), cardiovascular mortality in chronic kidney disease (PMID: 24308938), diastolic heart failure (PMID: 26010610, PMID: 27473038), and systolic heart failure (PMID: 27473038). It is also decreased in the blood or plasma of individuals with intracerebral hemorrhage (PMID: 29265114), carnitine palmitoyl transferase 1A deficiency (PMID: 11568084), and psoriasis (PMID: 33391503). It is found to be increased in feces of patients with cirrhosis (PMID: 23384618). 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 [Damb...

Levocarnitine
Used in sport and infant nutrition. Carnitine is a quaternary ammonium compound biosynthesized from the amino acids lysine and methionine. In living cells, it is required for the transport of fatty acids from the cytosol into the mitochondria during the breakdown of lipids (or fats) for the generation of metabolic energy. It is often sold as a nutritional supplement. Carnitine was originally found as a growth factor for mealworms and labeled vitamin Bt. Carnitine exists in two stereoisomers: its biologically active form is L-carnitine, while its enantiomer, D-carnitine, is biologically inactive.; Carnitine is not an essential amino acid; Levocarnitine is a carrier molecule in the transport of long chain fatty acids across the inner mitochondrial membrane. It also exports acyl groups from subcellular organelles and from cells to urine before they accumulate to toxic concentrations. Lack of carnitine can lead to liver, heart, and muscle problems. Carnitine deficiency is defined biochemically as abnormally low plasma concentrations of free carnitine, less than 20 µmol/L at one week post term and may be associated with low tissue and/or urine concentrations. Further, this condition may be associated with a plasma concentration ratio of acylcarnitine/levocarnitine greater than 0.4 or abnormally elevated concentrations of acylcarnitine in the urine. Only the L isomer of carnitine (sometimes called vitamin BT) affects lipid metabolism. The "vitamin BT" form actually contains D,L-carnitine, which competitively inhibits levocarnitine and can cause deficiency. Levocarnitine can be used therapeutically to stimulate gastric and pancreatic secretions and in the treatment of hyperlipoproteinemias.; There is a close correlation between changes in plasma levels of osteocalcin and osteoblast activity and a reduction in osteocalcin plasma levels is an indicator of reduced osteoblast activity, which appears to underlie osteoporosis in elderly subjects and in postmenopausal women. Administration of a carnitine mixture or propionyl-L-carnitine is capable of increasing serum osteocalcin concentrations of animals thus treated, whereas serum osteocalcin levels tend to decrease with age in control animals.; it can be synthesized in the body. However, it 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, and to some researchers carnitine is a vitamin (Liebovitz 1984). It was found that an animal (yellow mealworm) could not grow without carnitine in its diet. However, as it turned out, almost all other animals, including humans, do make their own carnitine; thus, it is no longer considered a vitamin. Nevertheless, in certain circumstances-such as deficiencies of methionine, lysine or vitamin C or kidney dialysis--carnitine shortages 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. Like the other amino acids used or manufactured by the body, carnitine is an amine. But like choline, which is sometimes considered to be a B vitamin, carnitine is also an alcohol (specifically, a trimethylated carboxy-alcohol). Thus, carnitine is an unusual amino acid and has different functions than most other amino acids, which are most usually employed by the body in the construction of protein. Carnitine is an essential factor in fatty acid metabolism in mammals. Its most important known metabolic function is to transport fat into the mitochondria of muscle cells, including those in the heart, for oxidation. This is how the heart gets most of its energy. In humans, about 25\\\\\%...

5-hydroxypentanoyl-CoA
5-hydroxypentanoyl-CoA is an acyl-CoA resulting from the formal condensation of the thiol group of coenzyme A with the carboxylic acid group of 5-hydroxypentanoic acid. It is functionally related to a pentanoyl-CoA and a 5-hydroxypentanoic acid. It is a conjugate acid of a 5-hydroxypentanoyl-CoA(4-). 5-Hydroxypentanoyl-coenzyme A is a thioester compound that plays a crucial role in various metabolic pathways, particularly in the biosynthesis of certain natural products and in the metabolism of fatty acids. It is formed by the condensation of 5-hydroxypentanoic acid with coenzyme A (CoA), which is a carrier molecule involved in the transfer of acyl groups. Chemically, 5-hydroxypentanoyl-CoA consists of a 5-hydroxypentanoyl group, which is a five-carbon acyl chain with a hydroxyl group attached to the fifth carbon, and the CoA moiety. The CoA part of the molecule includes a pantothenic acid (vitamin B5) derivative, a pyrophosphate group, and an adenine nucleotide. The acyl group is attached to the thiol (-SH) group of the CoA via a thioester linkage, which is a high-energy bond. In biological systems, 5-hydroxypentanoyl-CoA is an intermediate in the biosynthesis of polyketides, a large class of natural products that include many pharmaceuticals and other bioactive compounds. It can also be involved in the metabolism of fatty acids, where it may be converted into other compounds or used as a substrate for energy production. The presence of the hydroxyl group in the acyl chain of 5-hydroxypentanoyl-CoA confers specific chemical properties and reactivity to the molecule, making it a versatile building block in various biochemical pathways. Its role in these pathways highlights the importance of understanding its synthesis, metabolism, and regulation in biological systems.
