Serine is a kind of non essential amino acid, it plays an important role in metabolism of lipid and fatty acid and muscle growth, it helps to generate immunoglobulin and antibody and maintain a healthy immune system. Serine has function on manufacturing and processing of the cell membrane, synthesis of muscle tissue and shell of surrounding nerve cells.
