Histidine (symbol His or H) [2] is an essential amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated –NH 3 + form under biological conditions), a carboxylic acid group (which is in the deprotonated –COO − form under biological conditions), and an imidazole side chain (which is partially protonated), classifying it as a ...
d-Fructose-l-histidine (FruHis) is a ketosamine combining the d-isomer of fructose and the l-isomer of histidine into a functional group. FruHis is present in dried fruits . In interaction with lycopene , FruHis is a potential food related antioxidant and chemopreventive agent, found abundantly in dried tomatoes .
PubChem CID. 92893; UNII: ... Histidine methyl ester (HME) is an irreversible histidine decarboxylase inhibitor. [1] [2] [3] It is the methyl ester of histidine.
α-Fluoromethylhistidine (α-FMH) is an irreversible specific inhibitor of histidine decarboxylase (HDC). [1] It functions by forming a covalent linkage with a catalytic serine residue on the active site of HDC. Due to its efficacy in reducing histamine levels in tissue mast cells, it has many applications in the study of histaminergic systems. [2]

3-Methylhistidine (3-MH) is a post-translationally modified amino acid which is excreted in human urine. [1] [2] Urinary concentration of 3-methylhistidine is a biomarker for skeletal muscle protein breakdown in humans who have been subject to muscle injury.
2-Oxohistidine is a derivative of histidine damaged by reactive oxygen species. It is a biological marker for assessing protein modifications from oxidative stress. [1] In particular, it arises by iron-catalyzed reaction with hydrogen peroxide. [2]
