 |  | [Definition] 
 ChEBI: L-methionine S-oxide is a methionine S-oxide. It has a role as an Escherichia coli metabolite.
 |  | [Biochem/physiol Actions] 
 L-Methionine sulfoxide, a structural analog of glutamate, may be used as a substrate to study the specificity and kinetics of various methionine sulfoxide reductase(s).
 |  | [in vivo] 
 
 L-Methionine sulfoxide (150 μmol/rat; ip; once daily; 2-3 days) partially restores liver glutathione levels in male Wistar albino rats fed a 10% casein diet, but the extent of the restoration is less than that of an equal amount of methionine treatment[1]. L-Methionine sulfoxide (0.56%-1.66% dietary supplementation; p.o., dietary intake; daily ad libitum; 2 weeks) is approximately 60% efficient in utilizing methionine for growth in weanling rats and was not able to fully meet the dietary methionine requirement of rats[2].
