Description

White crystalline powder

Aspartic acid is an alpha-amino acid that consists of succinic acid bearing a single alpha-amino substituent It has a role as a fundamental metabolite. It is an alpha-amino acid, a C4-dicarboxylic acid and a polar amino acid. It contains a carboxymethyl group. It is a conjugate acid of an aspartate(1-) and an aspartate.|One of the non-essential amino acids commonly occurring in the L-form. It is found in animals and plants, especially in sugar cane and sugar beets. It may be a neurotransmitter.
