Metabolite Identification
Common NameN-Formyl-L-methionine
DescriptionN-Formyl-L-methionine, also known as fmet or for-met-OH, 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. N-Formyl-L-methionine is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa).
