L-Carnosine

L-카노신 C화학적 특성, 용도, 생산

화학적 성질

Crystalline

용도

antioxidant, antisenescense, antineoplastic

용도

L-Carnosine is a naturally-occurring histidine-containing compound and the biological role of this dipeptide is to act as cytosolic buffering agents. Other roles ascribed to L-Carnosine include action s as neurotransmitters, modulation of enzymic activities and chelation of heavy metals.

용도

carnosine is an anti-oxidant that works to prevent cellular damage because of free radical activity. Studies indicate an ability to boost the immunological functions. Carnosine is a naturally occurring amino acid. In cosmetics, it has anti-aging and skin-conditioning applications.

정의

ChEBI: A dipeptide that is the N-(beta-alanyl) derivative of L-histidine.

Safety Profile

Mildly toxic by intraperitoneal route. An experimental teratogen. Other experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Likely impurities are histidine and β-alanine. Crystallise L-carnosine from water by adding EtOH in excess. Recrystallise it from aqueous EtOH by slow addition of EtOH to a strong aqueous solution of the dipeptide. Its solubility in H2O is 33.3% at 25o.
