Metabolite Identification

Common Name

2-Aminoacrylic acid

Description

2-Aminoacrylic acid, also known as 2,3-didehydroalanine or 2-aminoacrylate, 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). 2-Aminoacrylic acid is a very strong basic compound (based on its pKa). 2-Aminoacrylic acid exists in all living species, ranging from bacteria to humans. Outside of the human body, 2-Aminoacrylic acid has been detected, but not quantified in, several different foods, such as wax gourds, soursops, durians, green beans, and grapes. This could make 2-aminoacrylic acid a potential biomarker for the consumption of these foods. A 2,3-dehydroamino acid that is alanine which has been dehydrogenated to introduce a double bond between positions 2 and 3.
