L-carnosine (β-alanyl-L-histidine) is a dipeptide of the amino acids β-alanine and histidine. It is highly concentrated in muscle and brain tissue. Carnosine has a variety of potentially beneficial antioxidant properties, which can remove reactive oxygen species and α-β unsaturated aldehydes formed by fatty acid peroxidation of cell membranes during oxidative stress. Carnosine is also a zwitterion, a neutral molecule with positive and negative ends. L-carnosine is a dipeptide with strong antioxidant and anti-glycation activities; blocks non-enzymatic glycosylation and protein cross-linking induced by reactive aldehydes. Product Name Anti Aging 99% Pure Carnosine,L Carnosine, L-Carnosine Powder Assay 99% Appearance White fine powder CAS No. 303-98-0 MF C9H14N4O3 Packaging 100g/bag, 1kg/bag Standand USP38 Shelf life Three years under well Storage situation and stored away from direct sun light   Food Applications L-carnosine not only can effectively inhibit fat oxidation, but also has high safety and health functions. Therefore, L-carnosine is an ideal food antioxidant with application value. Cosmetic Applications Used in cosmetics, it can prevent skin aging and skin whitening. Carnosine can prevent free radicals generated by smoking, and this free radical can damage the skin more than sunlight. Free radicals are very active in the human body. The atom or group of atoms can oxidize other substances in the human body. Medicine Applications 1. In addition to inhibiting the peroxidation process of the cell membrane, carnosine can also inhibit a series of peroxidation reactions in the cell, that is, carnosine can inhibit every step of the oxidation reaction in the entire peroxidation chain in the organism; 1. L-carnosine is the most effective antioxidant found so far. Carnosine helps the most destructive free radicals andprevents skin collagen from cross-linking, which can lead to loss of elasticity and wrinkles. Carnosine helps to chelate ionic metals and expel from the body. 2. L-carnosine can be used as a regulator of zinc and copper concentrations in nerve cells,helping to prevent excessive stimulation of these neuroactive substances in the body.
