The Characteristics and Uses: |
L-Serine (L-Ser), classified as a nonessential amino acid occurring in natural form as the L-isomer, is the form of serine which is used in protein synthesis and is readily assimilated by the digestive system, and it can not be synthesized in the human and animal body. And please notice that very high serine levels may cause immune suppression and psychological symptoms such as cerebral allergies. |
