组氨酸

由组氨酸脱羧酶催化的组氨酸转变为组胺

不要与组织胺(histamine, C5H9N3)混淆。

组氨酸（英语：Histidine，, C6H9N3O2）简写为His或H，α氨基酸结合咪唑官能团。是存在于蛋白质之中最普遍的23种氨基酸之一。初以为只针对婴幼儿是必需的，较长期的研究表明，它也是成年人必不可少的必需氨基酸。等电点为7.59，是碱性氨基酸，生理条件下带正电荷。他的合成密码子为 CAU 及 CAC。组氨酸在1896年由德国医师艾布瑞契·科塞尔(Albrecht Kossel)首次分离出来。

Histidine 组氨酸

The histidine-bound heme group of succinate dehydrogenase, an electron carrier in the mitochondrial electron transfer chain. The large semi-transparent sphere indicates the location of the iron ion. From PDB: 1YQ3​.
Various forms of histidine, showing the unphysiologic high-pH unrotonated form in the very center of the figure (it bears a negative charge, not shown, shared equally between the two nitrogens), and the neutral-pH singly protonated N3-H and N1-H tautomers at the lower left and right respectively. The physiologically relevant low-pH form, with two hydrogens and a positive charge shared equally between the two nitrogens, is not shown in this figure.
Conversion of histidine to histamine by histidine decarboxylase

Histidine (abbreviated as His or H; encoded by the codons CAU and CAC) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated –NH3 form under biological conditions), a carboxylic acid group (which is in the deprotonated –COO form under biological conditions), and a side chain imidazole, classifying it as a positively charged (at physiological pH). Initially thought essential only for infants, longer-term studies have shown it is essential for adults also.
