L-carnosine is a dipeptide (composed of two amino acids), which can be found in our brain, heart, skin, muscle, kidney, and stomach.
L-Carnosine CAS 305-84-0
Description
Introduction:
L-carnosine can activate the cells in human body and anti-aging through two mechanisms: the inhibitory effect of saccharification can protect our cells from damage by free radicals, because saccharifying results in crosslinking of uncontrolled sugar molecules and protein (sugar molecules can stick on the protein), and cell function is lost, and gene combinations are incomplete, which can accelerate ageing. L-carnosine can also maintain pH balance in the body and prolong cell life.
Functions:
- Anti-oxidant, anti-glycation, and anti-aging, which makes skin looks young and white;
- Anti-flammary and promote wound healing;
- Protect stomach from damages and ulcerations.
- Promote the normal metabolism of stomach;
- Regulate the concentration of zinc and copper in nerve cells.
