alpha-Carotene
alpha-Carotene belongs to the class of organic compounds known as carotenes. These are a type of unsaturated hydrocarbons containing eight consecutive isoprene units. They are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. alpha-Carotene is considered to be an isoprenoid lipid molecule. alpha-Carotene is one of the primary isomers of carotene. Plasma levels of alpha-carotene are positively associated with the detection rate of AFB1-DNA adducts in a dose-dependent manner, whereas plasma lycopene level was inversely related to the presence of the adducts in urine (PMID: 9214602). (6R)-beta,epsilon-carotene is an alpha-carotene. It is an enantiomer of a (6S)-beta,epsilon-carotene. alpha-Carotene is a natural product found in Hibiscus syriacus, Scandix stellata, and other organisms with data available. Widespread carotenoid, e.g. in carrots and palm oil. Has vitamin A activity but less than that of b-Carotene A cyclic carotene with a beta- and an epsilon-ring at opposite ends respectively.

Sodium_salicylate
Sodium salicylate is an organic molecular entity. Sodium Salicylate is the sodium salt of salicylic acid. As a nonsteroidal anti-inflammatory drug (NSAID), sodium salicylate irreversibly acetylates cyclooxygenases I and II, thereby inhibiting prostaglandin synthesis and associated inflammation and pain. This agent may also activate mitogen-activated protein kinase (p38MAPK), thereby inducing apoptosis in cancer cells. (NCI04) A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding.

2-Aminoisobutyric acid
2-Aminoisobutyric acid, also known as alpha-methylalanine or a-aminoisobutanoate, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 2-Aminoisobutyric acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2-Aminoisobutyric acid exists in all living organisms, ranging from bacteria to humans. Outside of the human body, 2-Aminoisobutyric acid has been detected, but not quantified in cow milk. Aminoisobutyric acid is a nonprotein amino acid (is an end product of pyrimidine metabolism) excreted in the urine of about 5\\\\\% of healthy individuals (PMID 14806475), and high excretion is an autosomal recessive phenotype (PMID 13058271). 2-aminoisobutyric acid is a rare, non-protein amino acid and end-product of pyrimidine metabolism, excreted in urine and found in some antibiotics of fungal origin. With the exception of a few bacteria, it is non-metabolisable, and therefore used in bioassays. It is functionally related to a propionic acid and an isobutyric acid.

N-Acetyl-L-phenylalanine
N-Acetyl-L-phenylalanine or N-Acetylphenylalanine, 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-Acetyl-L-phenylalanine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyl-L-phenylalanine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-phenylalanine. 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-acetylphenylalanine 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 phenylalanine can also occur. In particular, N-Acetyl-L-phenylalanine can be biosynthesized from L-phenylalanine and acetyl-CoA by the enzyme phenylalanine N-acetyltransferase (EC 2.3.1.53). N-Acetyl-L-phenylalanine is a potential uremic toxin and is considered as a hazardous amphipathic metabolite of phenylalanine (PMID: 4038506). Many N-acetylamino acids, including N-acetylphenylalanine, are classified as uremic toxins (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). N-Acetyl-L-phenylalanine appears in large amount in urine of patients with phenylketonuria (PKU), which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine (PMID: 3473611). N-Acetyl-L-phenylalanine is a product of enzyme phenylalanine N-acetyltransferase [EC 2.3.1.53] which is found in the phenylalanine metabolism pathway. N-Acetyl-L-phenylalanine is produced for medical, feed, and nutritional applications such as in the preparation of aspartame. Afalanine (N-Acetyl-DL-phenylalanine) is also approved for use as an antidepressant. Acetylphenylalanine is a hazardous amphipathic metabolite of phenylalanine. It appears in large amount in urine of patients with phenylketonuria which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine. Acetylphenylalanine is a product of enzyme phenylalanine N-acetyltransferase [EC 2.3.1.53] in the pathway phenylalanine metabolism. (KEGG; Wikipedia) [HMDB] N-Acetyl-L-phenylalanine (N-Acetylphenylalanine), the principal acylamino acid in Escherichia coli, is synthesized from L-phenylalanine and acetyl-CoA[1].
D-Alanyl-D-alanine
The ATP-dependent carboxylate-amine/thiol ligase superfamily is known to contain enzymes catalyzing the formation of various types of peptide, one of which is d-alanyl-d-alanine.(PMID: 16030213). The glycopeptide antibiotic vancomycin acts by binding to the D-alanyl-D-alanine terminus of the cell wall precursor lipid II in the cytoplasmic membrane.(PMID: 17418637). D-alanine-D-alanine ligase from Thermotoga maritima ATCC 43589 (TmDdl) was a useful biocatalyst for synthesizing D-amino acid dipeptides.D-Alanine-D-alanine ligase (Ddl) catalyzes the biosynthesis of an essential bacterial peptidoglycan precursor D-alanyl-D-alanine and it represents an important target for development of new antibacterial drugs. (PMID: 17267218). D-Alanyl-D-alanine is a microbial metabolite. Alanyl-alanine, also known as ala-ala or A-a dipeptide, is a member of the class of compounds known as dipeptides. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Alanyl-alanine is soluble (in water) and a weakly acidic compound (based on its pKa). Alanyl-alanine can be found in chives, which makes alanyl-alanine a potential biomarker for the consumption of this food product. Alanyl-alanine can be found primarily in feces. Alanyl-alanine exists in all living organisms, ranging from bacteria to humans. Acquisition and generation of the data is financially supported in part by CREST/JST. D-Ala-D-Ala constitutes the terminus of the peptide part of the peptidoglycan monomer unit and is involved in the transpeptidation reaction as the substrate. D-Ala-D-Ala is catalyzed by D-Alanine-D-Alanine ligase. D-Ala-D-Ala is a bacterial endogenous metabolite[1][2].
L-2,4-diaminobutyric acid
L-3-Amino-isobutanoic acid is a component of branched-chain amino acid biosynthesis and metabolism. It can also be used in pyrimidine metabolism.

KEIO_ID D038 L-DABA (L-2,4-Diaminobutyric acid) is a week GABA transaminase inhibitor with an IC50 of larger than 500 μM; exhibits antitumor activity in vivo and in vitro. L-DABA (L-2,4-Diaminobutyric acid) is a week GABA transaminase inhibitor with an IC50 of larger than 500 μM; exhibits antitumor activity in vivo and in vitro.
N-Acetylleucine
N-Acetyl-L-leucine or N-Acetylleucine, 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-Acetylleucine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetylleucine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lecuine. 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-acetylleucine 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 leucine can also occur. In particular, N-Acetylleucine can be biosynthesized from L-leucine and acetyl-CoA by the enzyme leucine N-acetyltransferase (EC 2.3.1.66). Excessive amounts N-acetyl amino acids including N-acetylleucine (as well as N-acetylglycine, N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylalanine, N-acetylmethionine and smaller amounts of N-acetylthreonine, N-acetylisoleucine, and N-acetylvaline) can be detected in the urine with individuals with acylase I deficiency, a genetic disorder (PMID: 16465618). Aminoacylase I is a soluble homodimeric zinc binding enzyme that catalyzes the formation of free aliphatic amino acids from N-acetylated precursors. In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency will experience convulsions, hearing loss and difficulty feeding (PMID: 16465618). ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. Many N-acetylamino acids, including N-acetylleucine 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).

Prostaglandin B1
Prostaglandin B1 (PGB1) is a metabolite of PGE1. PGE1 is a prostanoid. Prostanoids is a term that collectively describes prostaglandins, prostacyclines and thromboxanes. Prostanoids are a subclass of the lipid mediator group known as eicosanoids. They derive from C-20 polyunsaturated fatty acids, mainly dihomo-gamma-linoleic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2). PGB1does not inhibit phospholipase activity, but oligomers of PGB1 (PGBx) extracted from human neutrophils inhibit human phospholipases A2 in vitro and in situ in a dose-dependent manner; these oligomers inhibit arachidonic acid mobilization in human neutrophils and endothelial cells. One mechanism for the pharmacological effects of PGBx may be inhibition of cell-associated and extracellular phospholipase A2. PGB1 has the ability to enhance peripheral vascular resistance and elevate blood pressure. The effect is not central in origin and apparently is not the result of changes in cholinergic or alpha-adrenoceptor sensitivity or changes in vascular smooth muscle susceptibility per se. PGB1 blocks S-phase DNA synthesis; inhibition of DNA synthesis does not appear to require elevated levels of cAMP. (PMID: 7667505, 1477202, 2129000, 2597672, 6635328). 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. Prostaglandin B1 (PGB1) is a metabolite of PGE1. PGE1 is a prostanoid. Prostanoids is a term that collectively describes prostaglandins, prostacyclines and thromboxanes. Prostanoids are a subclass of the lipid mediator group known as eicosanoids. They derive from C-20 polyunsaturated fatty acids, mainly dihomo-gamma-linoleic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2).
Galactosylsphingosine
Galactosylsphingosine (also known as psychosine), is an intermediate in the biosynthesis of cerebrosides. It is formed from the reaction of sphingosine with UDP-galactose and then reacts with fatty acid-coenzyme A to form the cerebroside. It is a galactoside metabolite of sphingosine and can function as a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of galactosylsphingosine are associated with globoid cell leukodystrophy (Krabbe disease), which is characterized by the dysfunction of galactosylceramidase. Galactosylsphingosine is a highly cytotoxic lipid capable of inducing cell death in a wide variety of cell types including oligodendrocytes. It is known to accumulate in the nervous system in the absence of galactosylceramidase. Galactosylsphingosine localizes to lipid rafts and perturbs membrane integrity. It also inhibits protein kinase C translocation to the plasma membrane (PMID: 24006512). Symptoms of Krabbe disease begin between the ages of 3 and 6 months with irritability, fevers, limb stiffness, seizures, feeding difficulties, vomiting, and slowing of mental and motor development. In the first stages of the disease, the symptoms are often mistaken with those of cerebral palsy. Other symptoms include muscle weakness, spasticity, deafness, optic atrophy, optic nerve enlargement, blindness, paralysis, and difficulty when swallowing. An intermediate in the biosynthesis of cerebrosides. It is formed by reaction of sphingosine with UDP-galactose and then itself reacts with fatty acid-Coenzyme A to form the cerebroside.

3,5-Diiodo-L-tyrosine
3,5-Diiodo-L-tyrosine, also known as diiy or DIT, belongs to the class of organic compounds known as tyrosine and derivatives. Tyrosine and derivatives are compounds containing tyrosine or a derivative thereof resulting from reaction of tyrosine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. 3,5-Diiodo-L-tyrosine exists in all living organisms, ranging from bacteria to humans. In humans, 3,5-diiodo-L-tyrosine is involved in thyroid hormone synthesis. 3,5-Diiodo-L-tyrosine is a product from the iodination of monoiodotyrosine. A product from the iodination of monoiodotyrosine. In the biosynthesis of thyroid hormones, diiodotyrosine residues are coupled with other monoiodotyrosine or diiodotyrosine residues to form T4 or T3 thyroid hormones (thyroxine and triiodothyronine).

Terbutaline
Terbutaline is only found in individuals that have used or taken this drug. It is a selective beta-2 adrenergic agonist used as a bronchodilator and tocolytic. [PubChem]The pharmacologic effects of terbutaline are at least in part attributable to stimulation through beta-adrenergic receptors of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic- 3,5- adenosine monophosphate (c-AMP). Increased c-AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.

Prostaglandin A1
Prostaglandin A1 (PGA1, a prostaglandin characterized by a cyclopentenone structure) has a fundamental structure common to punaglandin and clavulone, the antitumor eicosanoids discovered in marine organisms such as corals. It is well established that PGA1, which exert potent antiviral activity in several DNA and RNA virus models, induce heat shock protein (hsp)70 syntheses through cycloheximide sensitive activation of heat shock transcription factor. Antitumor prostaglandins are actively incorporated through cell membrane and control gene expression. P53 (protein 53, is a transcription factor that regulates the cell cycle and functions as a tumor suppressor) independent expression of p21 (also known as cyclin-dependent kinase inhibitor 1A or CDKN1A, is a human gene on chromosome 6 (location 6p21.2), that encodes a cyclin-dependent kinase) and gadd 45 (growth arrest and DNA-damage-inducible, alpha 45, a major breast cancer (BRCA1) target is the DNA damage-responsive gene GADD45) activation of peroxisome proliferative activated receptor gamma (PPARgamma) are involved in antitumor mechanism of these prostaglandins. At the low concentration, these prostaglandins exhibit physiological or pathological activity such as osteoblast calcification, promotion of colon cancer cell proliferation. One of the mechanisms of anti-cancer activity of prostaglandins, has been believed to be that these prostaglandins might have p53 like effect in cells lacking p53.

Etodolac
Etodolac is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties. Its therapeutic effects are due to its ability to inhibit prostaglandin synthesis. It is indicated for relief of signs and symptoms of rheumatoid arthritis and osteoarthritis. Similar to other NSAIDs, the anti-inflammatory effects of etodolac result from inhibition of the enzyme cycooxygenase (COX). This decreases the synthesis of peripheral prostaglandins involved in mediating inflammation. Etodolac binds to the upper portion of the COX enzyme active site and prevents its substrate, arachidonic acid, from entering the active site. Etodolac was previously thought to be a non-selective COX inhibitor, but it is now known to be 5 – 50 times more selective for COX-2 than COX-1. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss.

L-Norleucine
L-Norleucine, also known as L-aminohexanoate or caprine, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Thus, L-norleucine is considered to be a fatty acid lipid molecule. An unnatural amino acid that is used experimentally to study protein structure and function. L-Norleucine is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. L-Norleucine exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, L-Norleucine has been detected, but not quantified in cow milk. This could make L-norleucine a potential biomarker for the consumption of these foods. It binds reversibly to the kringle domain of plasminogen and blocks the binding of plasminogen to fibrin and its activation to plasmin. An unnatural amino acid that is used experimentally to study protein structure and function. It is structurally similar to methionine, however it does not contain sulfur.

Sterigmatocystin is a toxic metabolite structurally closely related to the aflatoxins (compare general fact sheet number 2), and consists of a xanthone nucleus attached to a bifuran structure. Sterigmatocystin is mainly produced by the fungi Aspergillus nidulans and A. versicolor. It has been reported in mouldy grain, green coffee beans and cheese although information on its occurrence in foods is limited. It appears to occur much less frequently than the aflatoxins, although analytical methods for its determination have not been as sensitive until recently, and so it is possible that small concentrations in food commodities may not always have been detected. Although it is a potent liver carcinogen similar to aflatoxin B1, current knowledge suggests that it is nowhere near as widespread in its occurrence. If this is the true situation it would be justified to consider sterigmatocystin as no more than a risk to consumers in special or unusual circumstances. Sterigmatocystin is a number of closely related compounds such o-methyl sterigmatocystin are known and some may also occur naturally. The IARC-classification of sterigmatocystin is group 2B, which means it is possibly carcinogenic to humans. In practice, the risk is quite low however, because this substance only appears on cheese crusts with mold, and because of that the chance of daily exposure is very low. Sterigmatocystin is a molded crust is best not to be consumed in whole, but after removing the crust, the cheese can still be consumed. Sterigmatocystin is a different kind of mold than that which appears on cheese itself, which can simply be removed before further consumption D009676 - Noxae > D011042 - Poisons > D009183 - Mycotoxins CONFIDENCE Reference Standard (Level 1); INTERNAL_ID 2320

Liothyronine
Liothyronine is a T3 thyroid hormone normally synthesized and secreted by the thyroid gland in much smaller quantities than thyroxine (T4). Most T3 is derived from peripheral monodeiodination of T4 at the 5 position of the outer ring of the iodothyronine nucleus. The hormone that is finally delivered and used by the tissues is mainly T3. Liothyronine is mildly toxic by ingestion and is an experimental teratogen. When heated to decomposition it emits toxic fumes of NOx, I(-), and Cl(-) (Saxs Dangerous Properties of Industrial Materials).

Naphthalene
Naphthalene, also known as naftaleno or albocarbon, belongs to the class of organic compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. Naphthalene is possibly neutral. Naphthalene is a dry, pungent, and tar tasting compound. Naphthalene is found, on average, in the highest concentration within a few different foods, such as black walnuts, corns, and cloves. Naphthalene has also been detected, but not quantified, in several different foods, such as green bell peppers, orange bell peppers, rices, yellow bell peppers, and red bell peppers. This could make naphthalene a potential biomarker for the consumption of these foods. Naphthalene was once the primary ingredient in mothballs, though its use has largely been replaced in favor of alternatives such as 1,4-dichlorobenzene. Naphthalene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Inhalation of naphthalene vapor has been associated with headaches, nausea, vomiting and dizziness. Naphthalene is the most abundant single component of coal tar so most of it is now industrially derived from coal tar. Aside from coal tar, trace amounts of naphthalene are produced by magnolias and some species of deer, as well as the Formosan subterranean termite, possibly produced by the termite as a repellant against "ants, poisonous fungi and nematode worms."[23] Some strains of the endophytic fungus Muscodor albus produce naphthalene among a range of volatile organic compounds, while Muscodor vitigenus produces naphthalene almost exclusively (PMID:12427963).

Hydroxychloroquine
Hydroxychloroquine is only found in individuals that have used or taken this drug. It is a chemotherapeutic agent that acts against erythrocytic forms of malarial parasites.Although the exact mechanism of action is unknown, it may be based on ability of hydroxychloroquine to bind to and alter DNA. Hydroxychloroquine has also has been found to be taken up into the acidic food vacuoles of the parasite in the erythrocyte. This increases the pH of the acid vesicles, interfering with vesicle functions and possibly inhibiting phospholipid metabolism. In suppressive treatment, hydroxychloroquine inhibits the erythrocytic stage of development of plasmodia. In acute attacks of malaria, it interrupts erythrocytic schizogony of the parasite. Its ability to concentrate in parasitized erythrocytes may account for their selective toxicity against the erythrocytic stages of plasmodial infection. As an antirheumatic, hydroxychloroquine is thought to act as a mild immunosuppressant, inhibiting the production of rheumatoid factor and acute phase reactants. It also accumulates in white blood cells, stabilizing lysosomal membranes and inhibiting the activity of many enzymes, including collagenase and the proteases that cause cartilage breakdown.

PG(16:0/18:1(9Z))
PG(16:0/18:1(9Z)) is a phosphatidylglycerol or glycerophospholipid (PG or GP). It is a glycerophospholipid in which a phosphoglycerol moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PG(16:0/18:1(9Z)), in particular, consists of one chain of palmitic acid at the C-1 position and one chain of oleic acid at the C-2 position. The palmitic acid moiety is derived from fish oils, milk fats, vegetable oils and animal fats, while the oleic acid moiety is derived from vegetable oils, especially olive and canola oil. Phosphatidylglycerol is present at a level of 1-2\\% in most animal tissues, but it can be the second most abundant phospholipid in lung surfactant at up to 11\\% of the total. It is well established that the concentration of phosphatidylglycerol increases during fetal development. Phosphatidylglycerol may be present in animal tissues merely as a precursor for diphosphatidylglycerol (cardiolipin). Phosphatidylglycerol is formed from phosphatidic acid by a sequence of enzymatic reactions that proceeds via the intermediate, cytidine diphosphate diacylglycerol (CDP-diacylglycerol). Bioynthesis proceeds by condensation of phosphatidic acid and cytidine triphosphate with elimination of pyrophosphate via the action of phosphatidate cytidyltransferase (or CDP-synthase). CDP-diacylglycerol then reacts with glycerol-3-phosphate via phosphatidylglycerophosphate synthase to form 3-sn-phosphatidyl-1-sn-glycerol 3-phosphoric acid, with the release of cytidine monophosphate (CMP). Finally, phosphatidylglycerol is formed by the action of specific phosphatases. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PGs have a net charge of -1 at physiological pH and are found in high concentration in mitochondrial membranes and as components of pulmonary surfactant. PG also serves as a precursor for the synthesis of cardiolipin. PG is synthesized from CDP-diacylglycerol and glycerol-3-phosphate. PG(16:0/18:1(9Z)) is a phosphatidylglycerol. Phosphatidylglycerols consist of a glycerol 3-phosphate backbone esterified to either saturated or unsaturated fatty acids on carbons 1 and 2. As is the case with diacylglycerols, phosphatidylglycerols can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PG(16:0/18:1(9Z)), in particular, consists of one hexadecanoyl chain to the C-1 atom, and one 9Z-octadecenoyl to the C-2 atom. In E. coli glycerophospholipid metabolism, phosphatidylglycerol is formed from phosphatidic acid (1,2-diacyl-sn-glycerol 3-phosphate) by a sequence of enzymatic reactions that proceeds via two intermediates, cytidine diphosphate diacylglycerol (CDP-diacylglycerol) and phosphatidylglycerophosphate (PGP, a phosphorylated phosphatidylglycerol). Phosphatidylglycerols, along with CDP-diacylglycerol, also serve as precursor molecules for the synthesis of cardiolipin, a phospholipid found in membranes.

Nitrogen
Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78\\% by volume of Earths atmosphere. Nitrogen occurs in all living organisms. It is a constituent element of amino acids and therefore of proteins and nucleic acids (DNA and RNA). Nitrogen is found in the chemical structure of almost all neurotransmitters and is a key component of alkaloids. Specific bacteria (e.g. Rhizobium trifolium) possess nitrogenase enzymes which can fix atmospheric nitrogen into a form (ammonium ion) which is chemically useful to higher organisms. Animals use nitrogen-containing amino acids from plant sources, as starting materials for all nitrogen-compound animal biochemistry, including the manufacture of proteins and nucleic acids. Animal metabolism of NO (nitric oxide) results in production of nitrite. Animal metabolism of nitrogen in proteins generally results in excretion of urea, while animal metabolism of nucleic acids results in excretion of urea and uric acid. The characteristic odor of animal flesh decay is caused by nitrogen-containing long-chain amines, such as putrescine and cadaverine. Decay of organisms and their waste products may produce small amounts of nitrate, but most decay eventually returns nitrogen content to the atmosphere, as molecular nitrogen. The circulation of nitrogen from the atmosphere through organics and then back to the atmosphere is commonly referred to as the nitrogen cycle. Nitrogen can be measured in urine with the Kjeldahl method or by spectrophotometric methods (enzymic tests). Total urinary nitrogen is calculated based on urea urinary nitrogen quantified with these methods.

1-Hexadecanol
Cetyl alcohol, also known as 1-hexadecanol and palmityl alcohol, is a solid organic compound and a member of the alcohol class of compounds. Its chemical formula is CH3(CH2)15OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes. It belongs to the group of fatty alcohols. With the demise of commercial whaling, cetyl alcohol is no longer primarily produced from whale oil, but instead either as an end-product of the petroleum industry, or produced from vegetable oils such as palm oil and coconut oil. Production of cetyl alcohol from palm oil gives rise to one of its alternative names, palmityl alcohol. Flavouring ingredient.

Lipid A disaccharide
Prostaglandin A2
Produced by the seminal vesicles, prostaglandins are a group of lipid compounds that are derived enzymatically from fatty acids. Technically hormones, the prostanoid class of fatty acid derivatives is a subclass of 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 signaling pathways. Prostaglandin A is a cyclopentenone and is an endogenous metabolite derived from arachidonic acid. It exhibits potent cellular anti-proliferative activity in vivo and in vitro. Excess PGA2 causes an accumulation in both S and G2/M, and a marked decrease in G1. There is also an increase in DNA content preceeding the G0/G1 peak (indicative of apoptotic body formation) mediated by changes in expression levels of Bax and Bcl-2.

They derive from C-20 polyunsaturated fatty acids, mainly dihomo-gamma-linoleic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2). The reaction product of COX is the unstable endoperoxide prostaglandin H (PGH) that is further transformed into the individual prostanoids by a series of specific prostanoid synthases. Prostanoids are local-acting mediators formed and inactivated within the same or neighbouring cells prior to their release into circulation as inactive metabolites (15-keto- and 13,14-dihydroketo metabolites). Non-enzymatic peroxidation of arachidonic acid and other fatty acids in vivo can result in prostaglandin-like substances isomeric to the COX-derived prostaglandins that are termed isoprostanes. Prostanoids take part in many physiological and pathophysiological processes in practically every organ, tissue and cell, including the vascular, renal, gastrointestinal and reproductive systems. Their activities are mediated through prostanoid-specific receptors and intracellular signalling pathways, whilst their biosynthesis and action are blocked by nonsteroidal antiinflammatory drugs (NSAID). Isoprostanes are considered to be reliable markers of oxidant stress status and have been linked to inflammation, ischaemia-reperfusion, diabetes, cardiovascular disease, reproductive disorders and diabetes. (PMID: 16986207, 6252026, 6952267, 4019112, 6945633Prostaglandins 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.

Chloroform
Chloroform is found in spearmint. Indirect food additive arising from adhesives and polymers Chloroform is a common solvent in the laboratory because it is relatively unreactive, miscible with most organic liquids, and conveniently volatile. Chloroform is used as a solvent in the pharmaceutical industry and for producing dyes and pesticides. Chloroform is an effective solvent for alkaloids in their base form and thus plant material is commonly extracted with chloroform for pharmaceutical processing. For example, it is commercially used to extract morphine from poppies and scopolamine from Datura plants. Chloroform containing deuterium (heavy hydrogen), CDCl3, is a common solvent used in NMR spectroscopy. It can be used to bond pieces of acrylic glass (also known under the trade names Perspex and Plexiglas). Chloroform is a solvent of phenol:chloroform:isoamyl alcohol 25:24:1 is used to dissolve non-nucleic acid biomolecules in DNA and RNA extractions. Chloroform is the organic compound with formula CHCl3. It does not undergo combustion in air, although it will burn when mixed with more flammable substances. It is a member of a group of compounds known as trihalomethanes. Chloroform has myriad uses as a reagent and a solvent. It is also considered an environmental hazard. Several million tons are produced annually. The output of this process is a mixture of the four chloromethanes: chloromethane, dichloromethane, chloroform (trichloromethane), and carbon tetrachloride, which are then separated by distillation. The total global flux of chloroform through the environment is approximately 660000 tonnes per year, and about 90\\% of emissions are natural in origin. Many kinds of seaweed produce chloroform, and fungi are believed to produce chloroform in soil. Abiotic process is also believed to contribute to natural chloroform productions in soils although the mechanism is still unclear. Chloroform volatilizes readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow. Chloroform does not significantly bioaccumulate in aquatic organisms.

DG(16:0/18:1(9Z)/0:0)
DG(16:0/18:1(9Z)/0:0) is a diglyceride, or a diacylglycerol (DAG). It is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. Diacylglycerols can have many different combinations of fatty acids attached at both the C-1 and C-2 positions. DG(16:0/18:1(9Z)/0:0), in particular, consists of one chain of palmitic acid at the C-1 position and one chain of oleic acid at the C-2 position. The palmitic acid moiety is derived from fish oils, milk fats, vegetable oils and animal fats, while the oleic acid moiety is derived from vegetable oils, especially olive and canola oil. Mono- and diacylglycerols are common food additives used to blend together certain ingredients, such as oil and water, which would not otherwise blend well. Dacylglycerols are often found in bakery products, beverages, ice cream, chewing gum, shortening, whipped toppings, margarine, and confections. Synthesis of diacylglycerol begins with glycerol-3-phosphate, which is derived primarily from dihydroxyacetone phosphate, a product of glycolysis (usually in the cytoplasm of liver or adipose tissue cells). Glycerol-3-phosphate is first acylated with acyl-coenzyme A (acyl-CoA) to form lysophosphatidic acid, which is then acylated with another molecule of acyl-CoA to yield phosphatidic acid. Phosphatidic acid is then de-phosphorylated to form diacylglycerol.Diacylglycerols are precursors to triacylglycerols (triglyceride), which are formed by the addition of a third fatty acid to the diacylglycerol under the catalysis of diglyceride acyltransferase. Since diacylglycerols are synthesized via phosphatidic acid, they will usually contain a saturated fatty acid at the C-1 position on the glycerol moiety and an unsaturated fatty acid at the C-2 position. DG(16:0/18:1(9Z)/0:0) belongs to the family of Diacylglycerols. These are glycerolipids lipids containing a common glycerol backbone to which at least one fatty acyl group is esterified. DG(16:0/18:1(9Z)/0:0) is also a substrate of diacylglycerol kinase. It is involved in the phospholipid metabolic pathway.

1-Methyl-4-nitrobenzene
4-Nitrotoluene, being a volatile organic compound, can potentially penetrate the skin epidermis under certain conditions. The skin is a complex barrier that can prevent many substances from entering the body, but it is not impervious to all chemicals, especially those that are small, lipophilic (fat-soluble), and volatile. The epidermis, the outermost layer of the skin, consists of several sub-layers, including the stratum corneum, which is the primary barrier to external agents. Substances can pass through the skin via two main routes: transcellular (through the cells) and intercellular (between the cells). The efficiency of this penetration depends on various factors, such as the concentration of the compound, the duration of exposure, the condition of the skin (e.g., damaged or intact), and the chemical's properties. In the case of 4-nitrotoluene, if there is direct contact with the skin, especially in liquid or high vapor concentration forms, it could potentially penetration through the skin layers. This is particularly a concern in occupational settings where workers might be exposed to this compound without adequate protection. To minimize the risk of skin absorption, it is crucial to use appropriate personal protective equipment, such as gloves and aprons, when handling 4-nitrotoluene or any other potentially hazardous chemicals. In case of skin contact, it is important to wash the affected area immediately with soap and water and seek medical attention if necessary.
