General description
Aspartic acid(ASP)/aspartate, a non-essential amino acid, is naturally produced by mammals. ASP is one of the 20 building-block amino acids of proteins and has a one letter code, D. L-Aspartic acid can be manufactured industrially by an enzymatic process using the aspartase enzyme.
Application
L-Aspartic acid has been used:
- as an aspartame (ASP) metabolite to determine acetylcholinesterase (AChE) activity in the hippocampal homogenate of suckling rats[1]
- as printed chemotaxis ligands to screen chemotaxis receptors with high-throughput technologies and verify the interactions with surface plasmon resonance (SPR) and nuclear magnetic resonance (NMR)[2]
- as a supplement in Dulbecco′s modified Eagle′s medium (DMEM) for supplementation assays of various cultured cell lines[3]
Biochem/physiol Actions
Principal neurotransmitter for fast synaptic excitation.
