产品说明

一般描述

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.

应用

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

生化/生理作用

L-Aspartic acid is associated with protein biosynthesis (proteinogenic) and neurotransmission
快速突触兴奋的主要神经递质。
