Product Description


Amino acids and their derivatives are a class of compounds that contain both an amino group and a carboxyl group in the molecule. Appears in the body in free or combined state. Free amino acids are distributed in all animal cells and body fluids, and the binding amino acids are mainly the basic components of proteins and peptides.

Natural amino acids as colorless crystalline material, high melting point, most of them above 200 ℃. Usually soluble in water, insoluble in non-polar organic solvents. However, tyrosine and cystine are poorly soluble in water, and proline and carboxy proline are soluble in ethanol and ether. All amino acids are soluble in strong acid and alkali solution.

According to the polar nature of the side chain R groups in the α-amino acids, the 20 common amino acids that make up the protein can be divided into four groups:

① R groups are non-polar amino acids. There are 8 species, 5 species with aliphatic side chains, namely alanine, leucine, isoleucine, valine and proline, two kinds of aromatic amino acids, namely, phenylalanine and tryptophan Acid, a sulfur-containing amino acid, methionine; the solubility of this group of amino acids in water is less than the polar R-based amino acids; proline and the general α-amino acids, which is α-amino acid side-chain substitution A hydrogen atom on the amino acid formed, in fact, is an imino acid.

② R group polar but not charged amino acids. There are seven kinds, namely, R group hydroxyl serine, threonine and tyrosine, R group mercapto cysteine, R group amide group glutamine and asparagine, the other amino acid is glycine ; Glycine molecules without R group, but has a certain polarity, so attributed to this group; this group of amino acids side chains contain non-dissociation of the polar groups, with hydrogen to form hydrogen bonds, more easily soluble in water.

③ R base positively charged amino acids. There are 3 species, namely, lysine, arginine and histidine; carry a positive charge at pH 7.0, also known as basic amino acids.

Product expansion

1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.

2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period uut it can not be taken directly by patients.

3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.

4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.

5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
