Microbial fermentation usually takes glycerol, glucose and other biomass carbon sources as raw materials, and accumulates L-tyrosine through fermentation of excellent microbial strains under appropria

​L-tyrosine (Tyr) is an important nutritional essential amino acid, which plays an important role in human and animal metabolism, growth and development, and is widely used in food, feed, medicine and

Chemical synthesis is a method to produce or prepare amino acids by combining organic synthesis with chemical engineering. The chemical synthesis of DL tryptophan can be roughly divided into two kinds

The threonine (L-threonine) obtained by chemical synthesis is a mixture of four optical isomers, namely DL threonine. The amino acid constituting the protein is L-threonine, so it is necessary to sepa

The fermentation method is to use sugar, ammonia, homoserine as the culture medium, and refine the fermentation of glutaminus to produce L-threonine.

Take 5mL of the aqueous solution (1 → 1000) of the product, add 1mL of potassium chromate solution (1 → 1000) and boil it to produce a peculiar odor ②.

Nutritional supplements. One of the essential amino acids. In most food proteins, there are almost no restricted amino acids. It can be added to baked food. In addition to strengthening phenylalanine,

L-methionine, also known as L-methionine, is the left-handed body of methionine. Its chemical formula is C5H11NO2S. Its chemical property is colorless or white shiny flake crystal or white crystalline

Although lysine can also be extracted from the hydrolysate of protein raw materials (such as pig blood powder), the lysine used is mainly lysine hydrochloride produced by fermentation, and L-lysine is

The manufacture of amino acids began with the hydrolysis of proteins in 1820. The extraction sequence is L-cystine, L-histidine, L-leucine, L-arginine. In 1908, Japanese Ikeda found that sodium glutam

L-leucine is an essential amino acid with the chemical formula of C6H13NO2. It is an enantiomer with D-leucine. It is a white glossy hexahedral crystal or a white crystalline powder at room temperatur
