Overview:

Carnosine (scientific name: β-alanyl-L-histidine) is the dipeptide composed of two amino acids (i.e. β-alanine and L-histidine). It appears crystalline solid. Muscle and brain tissues contain high levels of carnosine. Carnosine is a compound found with carnitine by the Russian chemist Gulevich. Studies in the United Kingdom, South Korea, Russia and other countries have shown that carnosine has excellent antioxidant capacity and is beneficial to the human body. It is affirmed that carnosine can eliminate reactive oxygen free radicals (ROS) and α-β unsaturated aldehydes that are formed by the excessive oxidation of fatty acids in cell membranes during oxidative stress.

Efficacy overview:

1. Carnosine has a significant inhibitory effect on lipid oxidation caused by free radicals and metal ions. It can inhibit fat oxidation and protect meat color in meat processing. Carnosine and phytic acid can resist beef oxidation. Adding 0.9 g/kg carnosine to the diet can improve flesh color and oxidative stability of skeletal muscle, and has the synergistic effect with Vitamin E.

2. The application of carnosine in cosmetics can prevent skin aging and whiten skin. Carnosine can prevent the occurrence of free radicals caused by smoking. These free radicals will hurt the skin more than sunlight, as free radicals are highly active atoms or groups of atoms in the body that can oxidize other substances in the body.

3. Carnosine has antioxidant properties and acts as a natural antioxidant.

4. The use of carnosine as an antioxidant can treat senile cataracts.

5. Carnosine acts as an anti-glycation agent to reduce the rate of formation of advanced glycation end products (these substances may be factors in the development or worsening of many degenerative diseases, such as diabetes, atherosclerosis, chronic renal failure and Alzheimer's disease). It can ultimately reduce the formation of atherosclerotic plaques.

ECHEMI Editorial Reference

Crystalline
Solid
Carnosine is a dipeptide that is the N-(beta-alanyl) derivative of L-histidine. It has a role as an anticonvulsant, an antioxidant, an antineoplastic agent, a human metabolite, a Daphnia magna metabolite, a mouse metabolite, a neuroprotective agent and a geroprotector. It is a conjugate acid of a carnosinate. It is a tautomer of a carnosine zwitterion.|Carnosine has been investigated for the treatment of Gulf War Illness.|Carnosine is a dipeptide comprised of a beta-alanine and a 3-methyl-L-histidine, which is found in dietary red meat, with potential antioxidant, metal-chelating and anti-glycation activities. Carnosine scavenges both reactive oxygen species (ROS) and unsaturated aldehydes produced by cell membrane lipid peroxidation. Additionally, this dipeptide may reduce the rate of formation of advanced glycation end-products (AGE). Altogether, this may protect cells against oxidative damage. In addition, carnosine is able to chelate toxic metals.|A naturally occurring dipeptide neuropeptide found in muscles.
L-Carnosine is a dipeptide composed of β-alanine and L-histidine that has been found in rat olfactory bulb, skeletal muscle, brain, kidney, and spleen tissues, as well as human skeletal muscle, and has diverse biological activities. It is a metal chelator that forms complexes with copper, cobalt, nickel, cadmium, or zinc. Dietary administration of L-carnosine (60 mg/kg per day) reduces plasma levels of advanced glycation end products (AGEs) in diabetic rats. It reduces brain edema, blood-brain barrier disruption, microglial activation, and neuronal apoptosis in a rat model of intracerebral hemorrhage when administered at a dose of 1,000 mg/kg. L-Carnosine (250, 500, and 1,000 mg/kg, i.p.) reduces hepatic protein carbonylation and necrosis in a rat model of cirrhosis induced by bile duct ligation. It also reduces lung myeloperoxidase (MPO) activity, production of reactive oxygen species (ROS), and TNF-α and IL-6 levels, as well as alveolar hemorrhage, interstitial edema, and pulmonary leukocyte infiltration in a mouse model of LPS-induced lung injury.
