Chemical Information
FooDB Name1-aminocyclopropane-1-carboxylate
Description1-aminocyclopropanecarboxylic acid, also known as acc or 1-amino-1-carboxycyclopropane, is a member of the class of compounds known as alpha amino acids. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 1-aminocyclopropanecarboxylic acid is soluble (in water) and a moderately acidic compound (based on its pKa). 1-aminocyclopropanecarboxylic acid can be found in a number of food items such as american cranberry, chayote, sour cherry, and garden rhubarb, which makes 1-aminocyclopropanecarboxylic acid a potential biomarker for the consumption of these food products. ACC plays an important role in the biosynthesis of the plant hormone ethylene. It is synthesized by the enzyme ACC synthase ( EC from methionine and converted to ethylene by ACC oxidase (EC .
