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
