Nutrient Supply L Tyrosine Powder Edible Amino Acid Product Pharmaceutical
About L Tyrosine
Amino acids are derivatives which are produced by the substitution of hydrogen atoms on the hydrocarbon chain of carboxylic acids by amino acids. Amino acids are the basic structural units of proteins. There are usually 20 kinds of amino acids in natural proteins. Except proline, these amino acids are all α - amino acids.
According to the polarity of the side chain R group in α - amino acids, 20 common amino acids that make up the protein can be divided into four groups: (1) R group is nonpolar amino acid. (2) Amino acids with polar but uncharged R group. (3) R baseband is positively charged with amino acids. (4) The R group is a negatively charged amino acid. Tyrosine, serine and threonine belong to the amino acids with polarity but no charge of R group. Except glycine, the α - carbon atom in all α - amino acids is an asymmetric carbon atom, so it has optical activity. The optical rotation sign and size of amino acids depend on their R-group properties and are related to the pH of the solution at the time of determination. Among the 20 amino acids involved in protein composition, tyrosine, tryptophan and phenylalanine have the ability of light absorption, which is the basis for the determination of protein concentration by ultraviolet spectrophotometry (at the wavelength of 280nm).
