Opis

General description

Norvaline is a non-proteinogenic α-amino acid[1] and is also called DL-α-aminovaleric acid. It is produced in Gram-negative microorganisms including Escherichia coli and is also a part of the antifungal peptide produced by Bacillus subtilis.[2]

Application

DL-Norvaline has been used as an internal standard:

• to analyze metabolites in cultured mammalian cells by gas chromatography-mass spectrometry (GC-MS)[3][4]
• to convert cysteine and cystine to Cys MPA (S-2-carboxyethylthio-L-cysteine) and quantify the same using a high-performance liquid chromatography (HPLC) analyzer[5]
• for free amino acid analysis in samples of oocytes by liquid chromatography[6]

Biochem/physiol Actions

DL-Norvaline is a neurotransmitter.

Norvaline mediates physiological and pathophysiological processes promoting nitric oxide production. It is used to treat Alzheimer′s disease and is effective against artificial metabolic syndrome in rats.[7] Norvaline exhibits phase transition upon cooling below 190 K and hence it is useful in molecular machines.[1] DL-Norvaline serves as a prototype for research in polymorphism and molecular dynamics of aliphatic α-amino acids containing linear side-chain. It influences the activity, stability, and side-chain packaging of proteins.[2]
