Histidine
An essential amino acid, which the body cannot make and must obtain from the diet. Its imidazole ring makes it valuable in the active sites of many enzymes, and it is the precursor of histamine, a key player in allergic reactions. This family brings together labelled standards, nitrosamines and other impurities.
Did you know?Albrecht Kossel isolated it in 1896 from a protein in sturgeon sperm; the name probably comes from the Greek histos, linked to the idea of tissue, like that of the histones he had named himself.
