Function of L-Carnosine
L-carnosine is a natural dipeptide found in skeletal muscle, heart, brain and other nerve tissues. The combination of two amino acids is called a dipeptide. Therefore, L-carnosine is a combination of β-alanine and L-histidine.
The concentration of dipeptide decreases with age. Therefore, this type of nutritional supplement is also for anti-aging. L-carnosine can reduce glycation end products (AGEs), which is a variant protein that plays an important role in the aging process. In addition, carnosine also helps reduce cross-linked collagen that causes wrinkles and reduces skin elasticity. In other words, L-carnosine is good for slowing down the skin aging process.
Functions and benefits of L-carnosine
L-carnosine can also help prevent atherosclerosis, joint inflammation, and cataract formation. It can help body tissues get rid of a lot of toxins. The chemical structure of carnosine can bind certain metal toxins to prevent them from damaging the body. In addition, carnosine also helps regulate zinc and copper in the body.
Why do L-carnosine have these benefits?
Some evidence suggests that L-carnosine can protect cells from being killed by toxins, which are responsible for many neurological diseases. Sensitivity to glutamate is also a cause of toxin production and may cause damage to brain cells. Glutamate is the main excitatory neurotransmitter, so it is judged that L-carnosine has the potential to protect cells from death.
