While all amino acids are the building blocks of protein, they can be grouped into different categories based on their chemical properties. His, the abbreviation for histidine, belongs to the category of basic amino acids, characterized by its positively charged side chain. This unique characteristic plays a crucial role in its function within the body and in enzyme active sites.

According to a study on histidine metabolism, this essential amino acid serves multiple, complex roles within the human body. The main function of histidine stems from its unique imidazole side chain, which grants it versatile chemical properties for enzyme catalysis, protein structure stabilization, and the synthesis of key physiological compounds.
