DescriptionECHEMI Editorial ReferenceL-Aspartic acid is is an amino acid, shown to be a suitable prodrug for colon-specific drug deliverly.
Liquid|Solid|COLOURLESS CRYSTALS.|White crystals or crystalline powder; odourless
L-aspartic acid is the L-enantiomer of aspartic acid. It has a role as an Escherichia coli metabolite, a mouse metabolite and a neurotransmitter. It is an aspartate family amino acid, a proteinogenic amino acid, an aspartic acid and a L-alpha-amino acid. It is a conjugate acid of a L-aspartate(1-). It is an enantiomer of a D-aspartic acid.|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.Basic Info-
