DL-Histidine Chemical Properties,Usage,Production
Chemical Properties
white to slightly yellow crystalline powder
Uses
DL-Histidine has been used to study the fouling behaviour of polyethersulfone ultrafiltration membranes made with different PVP (polyvinylpyrrolidone).
Uses
histidine is a skin-conditioning amino acid.
Definition
ChEBI: An alpha-amino acid that is propanoic acid bearing an amino substituent at position 2 and a 1H-imidazol-4-yl group at position 3.

Biochem/physiol Actions
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.
