N-acetylhistidine isolated from frog heart.
A diazo-positive comitpound was found in an extract of frog heart. This substance showed a negative ninhydrin reaction and had on a paper chromatogram developed with a phenol-hydrochloric acid solvent system a higher R(F) than carnosine. The substance, isolated by chrolnatography, was identified as N-acetyl-L-histidine.
