L-Carnosine is a dipeptide (two amino acids) commonly found in organs and tissues such as the brain, heart, skin, muscles, kidneys, and stomach. L-carnosine can activate cells in the human body and resist aging through two mechanisms: inhibiting saccharification and protecting our cells from being damaged by the radicals from the Chemicalbook. The consequences of saccharification are that the cross-linking of sugar molecules and proteins will not be controlled (sugar molecules will stick to proteins), cell function loss and incomplete gene combination will accelerate aging. L-Carnosine can also stabilize cell membranes and reduce brain lipid peroxidation, thereby preventing nerve and brain degeneration. L-carnosine is a naturally occurring compound containing histidine, and its biological function is to act as a cell solute buffer. Other functions of L-carnosine include its role as a neurotransmitter, regulation of enzyme activity, and chelation of heavy metals.
