Dl-Methionine (CAS 59-51-8)

DL-Methionine is an essential amino acid containing sulphur. Methionine consists of an asymmetric carbon and exists as D (dextrogyre) and L (levogyre) optical isomers. The L-methionine is considered as biologically active. The racemic mixture of D and L-isomers forms DL-methionine, which is the commercially available methionine.

DL-Methionine has been used to study its effect on the growth and feed utilization of Nile tilapia. It has also been used as a part of standard diet in animal models.
