L(+)-Arginine

L-arginine is a coding amino acid in protein synthesis and is one of the eight essential amino acids for the human body. The body needs it to perform multiple functions. For example, it stimulates the release of specific chemicals in the human body, such as insulin and human growth hormone. This amino acid also helps clear ammonia from the body and has a promoting effect on wound healing. The human body also needs it to produce creatine.

APPLICATION

screenshot-1710377752065 Food industry: The 2-hydroxyacetaldehyde produced by heating L-serine with glucose has the aroma of maple syrup and can be used as a food additive. It can also be added as a nutrient to animal feed, improving the absorption and utilization rate of plant protein, and promoting animal growth and development.

screenshot-1716945839358 Cosmetics industry: L-serine can be added as a skin nutrient to high-quality cosmetics. As a key component of natural moisturizing factors, it has the function of moisturizing and delaying aging.

76a307224ae54a34b8d7f2989931dce1 Neuroprotective effects: Studies have shown that L-serine has neuroprotective effects that can improve neurological function, relieve learning and memory disorders, increase the number of regenerated neural stem cells, microvessels and astrocytes in brain tissue, as well as the content of nerve regeneration factors.
