Chemistry & industry
Applications
UsesDL-Norvaline is a neurotransmitter.
UsesDL-Norvaline has been used as an internal standard:to analyze metabolites in cultured mammalian cells by gas chromatography-mass spectrometry (GC-MS)to convert cysteine and cystine to Cys MPA (S-2-carboxyethylthio-L-cysteine) and quantify the same using a high-performance liquid chromatography (HPLC) analyzerfor free amino acid analysis in samples of oocytes by liquid chromatography
General DescriptionDL-Norvaline, a non-protein amino acid, is of significance in metabolic pathways. It is used as a food additive on account of its nutritional and functional characteristics that are beneficial to health.
Preparation methods
PreparationDL-Norvaline is produced from n-valeric acid as the starting material. Following acylation, α-bromination and hydrolysis of the acyl chloride, α-bromo-n-valeric acid is first obtained, and DL-norvaline is then produced via amination.
