詳細

詳細

Aspartic acid (Asp) is a non-essential amino acid. It makes up to 5% of the amino acids in a protein. The GAC and GAU codons encode Asp. This is a chiral molecule and occurs in two enantiomers namely L-Asp and D-Asp.

アプリケーション

L-Aspartic acid has been used:

• as a metabolite to study the enzyme–metabolite interactions in the central metabolism of Escherichia coli by nuclear magnetic resonance (NMR)
• in transmission electron microscopy
• as a component of complete media for culturing Yeast strain

生物化学的／生理学的作用

L-Aspartic acid is associated with protein biosynthesis (proteinogenic) and neurotransmission
