Histidine Amino Acid Structure What is Histidine? Study.com

WebbSeveral parameters were varied including pH of the bulk solution, histidine concentration, and performance of an annealing step during freezing. First, histidine was used as a buffer in the protein formulations and compared with "conventional" potassium phosphate and citrate buffer systems. The conjugate acid (protonated form) of the imidazole side chain in histidine has a pKa of approximately 6.0. Thus, below a pH of 6, the imidazole ring is mostly protonated (as described by the Henderson–Hasselbalch equation). The resulting imidazolium ring bears two NH bonds and has a positive charge. … Visa mer Histidine (symbol His or H) is an essential amino acid that is used in the biosynthesis of proteins.
