Metabolite Identification
Common NameDL-2-Aminooctanoic acid
DescriptionDL-2-Aminooctanoic acid, also known as a-aminocaprylate or alpha-aminocaprylic acid, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). DL-2-Aminooctanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, DL-2-Aminooctanoic acid has been detected, but not quantified in, milk (cow). This could make DL-2-aminooctanoic acid a potential biomarker for the consumption of these foods.
