The scientific name is glycine. The simplest and only alpha-amino acid without an optical isomer. In 1820, the chemist Bracono treated gelatin with hydrochloric acid to obtain a sweet substance. He was initially mistaken for a saccharide compound, which was later analyzed to be a nitrogen-containing compound with a carboxyl group and can be used in manufacturing. Ammonia. Named glycine. It is usually in the shape of a four-sided column, colorless monoclinic crystal, density 1. 160 7 g / cm 3 , melting point 232 ~ 236 ° C (decomposition), soluble in water, insoluble in ether and other organic solvents. It has a sweet taste and is a neutral amino acid with an isoelectric pH of 6. It is oxidized by ninhydrin in aqueous solution to form formaldehyde, which can be dissolved in strong acid or strong alkali, and is amphoteric and can be precipitated by alcohol. Commonly used α-halo acid and concentrated ammonia to prepare. Glycine is involved in the synthesis of many important compounds in animals. It can form terpenoids with ammonia, formic acid and carbon dioxide. It can synthesize porphyrins with succinic acid. It is one of synthetic raw materials such as creatine, glycocholic acid, and glutathione. It acts as a detoxification in the human body. For example, when aromatic substances enter the human body, glycine combines with them to form a non-toxic substance, which is then oxidized by the liver and then excreted. For example, the action of benzoic acid (preservative) to form hippuric acid is excreted. The formation of serine is catalyzed by hydroxymethylase. In recent years, glycine has been used as an amino acid pesticide. For example, 2.5 kg of 85% glycine solution is sprayed on a sugar cane field every 10,000 m 2 (15 mu), which can increase the sugar cane content by 12.9%. In 1973, the N-methyl phosphate glycine produced by the German chemist Smex was an effective herbicide. The weeds were eliminated by using 1.5 kg per 10,000 m2. Glycine can also be used to manufacture some anticancer drugs, for example, a series of anticancer drugs made by the action of glycine and diazonium compounds have significant effects on gastric cancer and the like. Glycine is now in large quantities.
