Metabolite Identification
Common NameOctadecanedioic acid
DescriptionOctadecanedioic acid, also known as 1,18-octadecanedioate or octadecane-1,18-dioate, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. In the case of octadecanedioic acid, it has carboxyl groups at both ends of the chain, not just one. Octadecanedioic acid is a very hydrophobic molecule, practically insoluble (in water). Octadecanedioic acid is a long-chain dicarboxylic acid normally not found in humans that has been identified in the blood serum in Reye's syndrome patients (PMID: 3746531). There may also be an association with colorectal cancer (PMID: 25037050 ).
