Natural Product Identification
Common Name5-Hydroxyhexanoic acid
Description5-Hydroxyhexanoic acid, also known as 5-hydroxycaproate or 5-OH-caproic acid, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. 5-Hydroxyhexanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 5-Hydroxyhexanoic acid was first documented in 1978 (PMID: 640132). 5-Hydroxyhexanoic acid, with regard to humans, has been found to be associated with the diseases such as colorectal cancer; 5-hydroxyhexanoic acid has also been linked to the inborn metabolic disorder medium chain acyl-coa dehydrogenase deficiency (PMID: 6897376) (PMID: 575058) (PMID: 6795215) (PMID: 8406236) (PMID: 2239769).
