L-Glutamine
Introduction
L-glutamine is also known as glutenamide and L-glutamic acid-5-amide. White needle-shaped crystal or powder. The molecular weight is 146.15. Melting point 184～185℃. Soluble in water, insoluble in methanol, ethanol, ether, benzene, acetone, chloroform, ethyl acetate Chemicalbook. Stabilised in a neutral solution. It is easy to decompose into glutamic acid in acid or hot water, or to be esterified into pyrrole carboxylic acid. No smell. It has a slightly sweet fragrance. This product is converted into hexesamine in the body, which can promote ulcer healing as a precursor for the synthesis of mucinous proteins. It is mainly used as a medicine for gastrointestinal ulcers.
