【Function】In medicine,High optical purity of L-Alanine is an important chiral source used in synthesis of many types of drugs. And it is raw material to compose amino acid injection and oral liquid. In food industry, l-alanine is added in chemistry seasoning, drinks, organic acid, wine and salted food. As one important additive, l-alanine has the fuction of keeping fresh. |
