Chemical Information
FooDB NameN-Acetylhistidine
DescriptionN-Acetylhistidine belongs to the class of organic compounds known as histidine and derivatives. Histidine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-Acetylhistidine is a very strong basic compound (based on its pKa). N-Acetylhistidine has been detected, but not quantified in, fishes and milk (cow). This could make N-acetylhistidine a potential biomarker for the consumption of these foods.
