설명

애플리케이션

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.

생화학적/생리학적 작용

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.

Precursor of histamine by action of histidine decarboxylase.
