Metabolite Identification
Common Name(+)-12-Methyltetradecanoic acid
Description12-methyltetradecanoic acid, also known as 15:0ai or anteiso-15:0, 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. 12-methyltetradecanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
