Function:
1. Participate in choline synthesis, with the function of fat, prevent arteriosclerosis hyperlipidemia
2. improves the function of muscle activity
3. Promote skin protein and insulin synthesis
4, the lack of it can cause liver and kidney disorders. Necessary for the protection of liver function, especially, can promote hair, nail growth, and has detoxification and enhance muscle activity and so on.
Application：
1. It’s a nutritional supplement, having the same physiological effects of L-type ethionine;
2. It’s related to sea urchin flavor and can be formulated to liquid seasoning;
3. It can be used to make amino acid infusion and comprehensive amino acid preparations.
4. It can be used as a spice.
