OriginDerived from long-chain fatty acids or produced synthetically from petrochemical or bio-based starting materials. Synthesized through oxidation and reduction reactions of decanoic acid precursors to introduce the hydroxyl functional group.
10-hydroxycapric acid is a 10-carbon, -hydroxy fatty acid, shown to be the preferred hydroxylation product (together with the 9-OH isomer) of capric acid in biosystems, and used as a standard in lipid assays; reported to have cytotoxic effects. It is an omega-hydroxy-medium-chain fatty acid and a straight-chain saturated fatty acid. It is functionally related to a decanoic acid. It is a conjugate acid of a 10-hydroxycaprate.
