Other Amino Acids
Take an appropriate amount of this product, add water to dissolve and dilute to make a solution containing about 20mg per lml as a test solution; Take 1ml for precision measurement and put it in a 200ml measuring flask, dilute to the scale with water, shake well, as a control solution; Take the appropriate amount of serine reference and methionine reference respectively, and place in the same measuring flask, water was added to dissolve and diluted to prepare a solution containing about 0.4mg each per 1ml as a system-suitable solution. According to the thin layer chromatography (General 0502) test, absorb the above three solutions each 5 u1, respectively, on the same silica gel G thin layer plate, with n-butanol-water-glacial acetic acid (3:1:1) for development, after deployment, air-drying, spraying with ninhydrin in acetone solution (1-50), heating at 80°C until spots appear, and examination immediately. The control solution should show a clear spot, and the system applicable solution should show two completely separated spots. If the test solution shows impurity spots, the color should not be deeper (0.5%) than the main spot of the control solution.

D-Serine (H-D-Ser-OH) (CAS: 312-84-5) is the D-form of the amino acid serine, but is not used for the protein synthesis. Amino acids are among the most significant molecules in nature and exist in an l- and a d-form. The chemical and physical properties of l- and d-amino acids are enormously similar except for their optical characteristics[1]. During the emergence of life, only the l-amino acids were selected for the formation of polypeptides and proteins.
Amino acids and derivatives, used in peptide synthesis, used as an organic synthesis intermediate, pharmaceutical intermediate, can be used as a chiral intermediate, biochemical reagent or chemical reagent.
D-Serine is involved in the biosynthesis of purines, pyrimidines, and other amino acids. D-Serine also is an agonist of glycine site of the NMDA-type glutamate receptor. It also acts as Lacosamide intermediate.
Production method DL-serine and chloroacetyl chloride are used as raw materials under alkaline conditions, evaporated to dry under reduced pressure, extracted with ethyl acetate, and the product is obtained after treatment with activated carbon and resolution with acylase I.
