L-라이신 is an essential amino acid that cannot be synthesized by the human body and must be obtained through diet or supplementation. It is the most limiting amino acid in cereal-based diets. This makes it critical for food fortification in many regions.
L-라이신 plays vital roles in protein synthesis, calcium absorption, collagen formation, and immune function. It is produced on a massive industrial scale through microbial fermentation, primarily for use in animal feed and human nutrition. L-라이신 is available as the free base and in various salt forms to suit different application requirements and stability needs.
