Description_x000D_ Amino Acid Sequence_x000D_ Ala-His_x000D_ Application_x000D_ L-Carnosine has been used to study its effects as an antioxidant on meat quality of pigs. It has also been used to study its effects on brain injury in a rat intracerebral hemorrhage model._x000D_ Packaging_x000D_ 10 mg in poly bottle_x000D_ 5, 25, 100 g in poly bottle_x000D_ Biochem/physiol Actions_x000D_ L-Carosine is a dipeptide found at millimolar concentration in brain, muscle and the lens of the eye. In model systems it is a potent antioxidant that scavenges oxygen free radicals and transition metal ions. It blocks protein-protein and protein-DNA cross-links induced by hypochlorite anions and toxic aldehydes such as acetaldehyde, formaldehyde, and malondialdehyde, the primary product of lipid peroxidation. It also inhibits nonenzymatic protein glycation induced by aldose and ketose reducing sugars and inhibits the formation of toxic advanced glycation end products (AGE). These activities make it of interest in studies of aging, atherosclerosis, Alzheimer′s disease, and the secondary effects of diabetes._x000D_ Dipeptide with potent antioxidant and antiglycation activity; blocks nonenzymatic glycosylation and protein cross-linking induced by reactive aldehydes._x000D_ Other Notes_x000D_ Tandem Mass Spectrometry data independently generated by Scripps Center for Metabolomics is available to view or download in PDF.
