(2S,4S,5R,6R)-2,4-dihydroxy-5-(2-hydroxyacetamido)-6-[(1R,2R)-1,2,3-trihydroxypropyl]oxane-2-carboxylic acid

C11H19NO10 (325.1009)


N-Glycolylneuraminic acid (Neu5Gc) is a widely expressed sialic acid found in most mammalian cells. Although humans are genetically deficient in producing Neu5Gc, small amounts are present in human cells and biofluids. Humans cannot synthesize Neu5Gc because the human gene CMAH is irreversibly mutated, though it is found in apes. This loss of the CMAH gene was estimated to have occurred two to three million years ago, just before the emergence of the genus Homo. A dietary origin of Neu5Gc was suggested by human volunteer studies. These trace amounts of Neu5Gc were determined to come from the consumption of animals in the human diet (i.e. red meats such as lamb, pork, and beef). Neu5Gc can also be found in dairy products, but to a lesser extent. Neu5Gc is not found in poultry and is found in only trace amounts in fish (Wikipedia). Isolated from beef serum KEIO_ID G062

   

Dephospho-CoA

[({[(2R,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}(hydroxy)phosphoryl)oxy][(3R)-3-hydroxy-2,2-dimethyl-3-({2-[(2-sulfanylethyl)carbamoyl]ethyl}carbamoyl)propoxy]phosphinic acid

C21H35N7O13P2S (687.1489)


Dephospho-CoA, also known as 3-dephospho-CoA, belongs to the class of organic compounds known as purine ribonucleoside diphosphates. These are purine ribonucleosides with a diphosphate group linked to the ribose moiety. Thus, dephospho-CoA is considered to be a fatty ester lipid molecule. Dephospho-CoA is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, dephospho-CoA has been detected, but not quantified in, several different foods, such as wild leeks, summer savouries, arctic blackberries, biscuits, and persimmons. This could make dephospho-CoA a potential biomarker for the consumption of these foods. Dephospho-CoA is an intermediate in pantothenate and CoA biosynthesis. It is a substrate for bifunctional coenzyme A synthase which contains the dephospho-CoA kinase (EC 2.7.1.24). This enzyme catalyzes the final step in CoA biosynthesis: the phosphorylation of the 3-hydroxyl group of ribose using ATP as a phosphate donor. The reaction is ATP + 3-dephospho-CoA = ADP + CoA. Dephospho-CoA is a substrate for Ectonucleotide pyrophosphatase/phosphodiesterase 1, Ectonucleotide pyrophosphatase/phosphodiesterase 3 and Ectonucleotide pyrophosphatase/phosphodiesterase 2. [HMDB]. Dephospho-CoA is found in many foods, some of which are cardamom, epazote, lemon balm, and mammee apple. Acquisition and generation of the data is financially supported in part by CREST/JST.
