S-Methyl-L-cysteine Chemical Properties,Uses,Production
Chemical Properties
white to light beige fine crystalline powder
Uses
S-Methyl-L-cysteine is a substrate in the catalytic antioxidant system mediated by methionine sulfoxide reductase A (MSRA). It has been studied as a theurapeutic for neurodegenerative diseases including Parkinson′s.
Definition
ChEBI: A cysteine derivative that is L-cysteine in which the hydrogen attached to the sulfur is replaced by a methyl group.
Purification Methods
Likely impurities are cysteine and S-methyl-dl-cysteine. Crystallise it from H2O by adding 4volumes of EtOH. It also crystallises from MeOH with m 234-236o(dec), but after sublimation i t has m 267-270o and [] 27D -31.6o (c 1, H2O). [Rinderknecht et al.
