Metabolite Identification
Common NameCaprylic acid
DescriptionCaprylic acid is the common name for the eight-carbon straight-chain fatty acid known by the systematic name octanoic acid. It is found naturally in coconuts and breast milk. It is an oily liquid with a slightly unpleasant rancid taste that is minimally soluble in water. Caprylic acid is used commercially in the production of esters used in perfumery and also in the manufacture of dyes (Wikipedia). Caprylic acid can be found in numerous foods such as Prunus (Cherry, Plum), pineapple sages, black raspberries, and shallots. Caprylic acid is found to be associated with medium-chain acyl-CoA dehydrogenase deficiency, which is an inborn error of metabolism.

General function:
Involved in ion transmembrane transporter activity
Specific function:
Involved in the renal elimination of endogenous and exogenous organic anions. Functions as organic anion exchanger when the uptake of one molecule of organic anion is coupled with an efflux of one molecule of endogenous dicarboxylic acid (glutarate, ketoglutarate, etc). Mediates the sodium-independent uptake of 2,3-dimercapto-1-propanesulfonic acid (DMPS). Mediates the sodium-independent uptake of p- aminohippurate (PAH), ochratoxin (OTA), acyclovir (ACV), 3'-azido- 3-'deoxythymidine (AZT), cimetidine (CMD), 2,4-dichloro- phenoxyacetate (2,4-D), hippurate (HA), indoleacetate (IA), indoxyl sulfate (IS) and 3-carboxy-4-methyl-5-propyl-2- furanpropionate (CMPF), cidofovir, adefovir, 9-(2- phosphonylmethoxyethyl) guanine (PMEG), 9-(2- phosphonylmethoxyethyl) diaminopurine (PMEDAP) and edaravone sulfate. PAH uptake is inhibited by p- chloromercuribenzenesulphonate (PCMBS), diethyl pyrocarbonate (DEPC), sulindac, diclofenac, carprofen, glutarate and okadaic acid. PAH uptake is inhibited by benzothiazolylcysteine (BTC), S-chlorotrifluoroethylcysteine (CTFC), cysteine S-conjugates S-dichlorovinylcysteine (DCVC), furosemide, steviol, phorbol 12-myristate 13-acetate (PMA), calcium ionophore A23187, benzylpenicillin, furosemide, indomethacin, bumetamide, losartan, probenecid, phenol red, urate, and alpha-ketoglutarate
