Common Name

N-Acetyl-3-methylhistidine

Description

N-Acetyl-3-methylhistidine, an N-acetyl-L-amino acid, belongs to the class of organic compounds known as histidine and derivatives. Histidine and derivatives are compounds containing histidine or a derivative thereof resulting from a reaction of histidine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-Acetyl-3-methylhistidine is an acetylated derivative of 3-methylhistidine and a very strong basic compound (based on its pKa). N-Acetyl-3-methylhistidine has been found to be associated with prostate cancer (PMID: 28423352 ).
