DescriptionD-Methionine, also known as MED, belongs to the class of organic compounds known as methionine and derivatives. Methionine and derivatives are compounds containing methionine or a derivative thereof resulting from reaction of methionine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. D-Methionine is a very strong basic compound (based on its pKa). D-Methionine exists in both E. coli (prokaryote) and yeast (eukaryote).
