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.

Synthesis Reference(s)

Journal of the American Chemical Society, 67, p. 502, 1945 DOI: 10.1021/ja01219a513
Chemical and Pharmaceutical Bulletin, 35, p. 3447, 1987

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.
