have sensitive color reactions. The simplest structure of glycine was found in the hydrolytic products of proteins in 1820, and by 1940 about 20 amino acids had been found in nature. They are necessary for human or animal synthesis of proteins, mostly L-α-amino acids. Amino acids are divided into neutral amino acids (glycine, alanine, liganine, isoestine, proline, cysteine, cysteine, methionine, suline, serine, serine, serine, phenylalanine, tyrosine, tryptophan, proline and hydroxyproline, etc.) according to the different amino acid molecules. It contains only one amino and one arginine; the acidic amino acids (glutamate, Tianmen dong amino acids), which contain one amino and two arginine molecules; the alkaline amino acids (lysine, arginine) contain a dino acid, and the amino acid nitrogen ring, which is weakly alkaline and is also an alkaline amino acid. Amino acids can be hydrolysed from proteins or chemically synthesized. Since the 1960s, the industrial production of

fermentation method, such as MSG plants have generally switched to fermentation method to produce glutamate. In recent years, petroleum hydrocarbons and other chemical products have been used as raw materials for amino acid fermentation to produce amino acids.
the amino acids that make up protein have certain nutritional value, with an appropriate proportion of amino acid mixture can be directly injected into the human blood to supplement nutrition, partially replace plasma, trauma, burns and post-surgery patients have enhanced resistance to disease, promote the role of rehabilitation. Histamines, arginine, tianmen dongine, glutamate and sulfur-containing amino acids have certain effects on liver diseases such as inflamed hepatitis. Cysteine is also resistant to radiation and treats heart failure. Various essential amino acids have a health and nutritional effect to maintain the normal development of the human body and animals. Adding lysine to food can increase its nutritional value. Some people abroad use amino acids to make man-made fibers, man-made leather and plastics. Use glycine to prevent rubber aging. Antioxidants and antioxidants made from tryptophan and

Six companions of poor light eggs,
acid valley days out,
dead pig liver face,
only carry one or two money.
a book of falling colors,
to read it carefully.
the fragrant old nature, do
not rob Gansu.
Six with poor eggs: sulfur, half, light, egg →suld, light, egg (methionine) →insulfur amino acid
acid valley day out: acid, valley, day →glutamate, tianmen dongine →alic acid
dead pig liver Color face: silk, group, glyceline, color → silk, group, glyceline, tryptophan→ a carbon unit source of amino acids
only carry one or two money: branch, palladium, bright→
→: iso, benzene, tyrosine, color, su→ iso-bright, phenylpropyl, tee, color, suline →saccharides and ketones
picked to read carefully: alkali, Lai, refined, group→ lysine, arginine, histamine →alic amino acids
aromatic old book Color: aromatic, tyrosine, benzene, color → tyrosine, phenyl, tryptophan → Aromatic amino acids
do not rob Gansu: arginus, hydroxy, glyceline, Su, lai→pronam, hydroxypropyl, glyceline, su, lysine→ do not participate in transamino amino acids
