Application

L-Histidine has been used for characterization of ZnO nanorod in an attempt to develop a technique for the ultra-low level detection of l-histidine.

Biochem/physiol Actions

Precursor of histamine by action of histidine decarboxylase.
L-Histidine is involved in the one-carbon unit metabolism. It is associated with protein methylation. L-Histidine is a part of hemoglobin structure and function. L-Histidine is a component of dipeptides with antioxidative property. Histidine serves as a precursor for the formation of histamine, which is associated with allergic responses. Urocanic acid, an immune response modulator in skin is also biosynthesised from histidine.
