Verwenden

antioxidant, antisenescense, antineoplastic

Verwenden

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.

Verwenden

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.

Definition

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

Sicherheitsprofil

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

läuterung methode

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.
