Descrizione

Descrizione generale

Aspartic acid (Asp) is a non-essential amino acid.[1] It makes up to 5% of the amino acids in a protein.[2] The GAC and GAU codons encode Asp. This is a chiral molecule and occurs in two enantiomers namely L-Asp and D-Asp.[3]

Applicazioni

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)[4]
• in transmission electron microscopy[5]
• as a component of complete media for culturing Yeast strain[1]

Azioni biochim/fisiol

L-Aspartic acid is associated with protein biosynthesis (proteinogenic) and neurotransmission[3]

Principal neurotransmitter for fast synaptic excitation.
