产品描述
Biochem/physiol Actions
L-Histidine is biosynthesized from ATP, 5-phosphoribosyl-1-pyrophosphate (PRPP), and glutamine. This essential amino acid can be degraded to glutamate by histidiase, urocanase and imidazolonepropionase; it is also the precursor of histamine by action of histidine decarboxylase.
General description
L-Histidine is a hydrophilic essential amino acid that has a basic sidechain containing an imidazole group.
