What is the difference between natural amino acids and amino acids that contain chemical components?

99% of domestic amino acids are synthesized by chemistry, so that heavy metals and toxic elements increase, which is very harmful to human health, when the fertilizer enters the soil, it will increase the concentration of the soil solution and produce osmotic pressure of different sizes, crop root cells not only can not absorb water from the soil solution, but pour the water in the cytoplasm into the soil solution, which leads to crop damage, a typical example is crops"Burn seedlings"。The soil can also be contaminated, the physical properties of the soil deteriorate, and the harvest is reduced. Long-term excessive application of chemical fertilizers can acidify the soil, causing pesticide residues or penetrating deep into groundwater, and polluting water sources.

The natural amino acids produced by Henan Chunguying Biotechnology are 100% decomposed by natural microorganisms, and the cell walls of animals are broken through high-speed separators and then fermented, containing more than 20 kinds of amino acids, especially containing 9 kinds of necessary amino acids, which are high-purity and high-quality products. At the same time, natural amino acids can improve the soil and environment, thereby improving the quality of crops and increasing the harvest, which greatly increases the income of farmers.

Amino acids refer to carboxylic acids that contain amino groups. The various proteins in living organisms are made up of 20 basic amino acids. Except for glycine, all are l amino acids, among which (proline is an l amino acid), and its structure is as shown in the figure (r group is a variable group):

Except for glycine, the carbon atoms of other protein amino acids are asymmetric carbon atoms (i.e., the four substituents bonded to the carbon atoms are different), so amino acids can have stereoisomers, that is, they can have different configurations (D type and L type).[1]

What are amino acids, learn about amino acids in a minute.

NaturalAmino acidsThere are more than 300 kinds, but most of them are not involved in the composition of proteins, and there are 20 kinds of natural amino acids that make up proteins, namely tryptophanLysine, phenylalanine, methionine, threonine, valine, leucine, isoleucine, cysteine, serine,Glycine, tyrosine,Aspartic acid, asparagine, glutamic acid, glutamine, alanine, arginine, histidine, proline

The basic backbone of a protein molecule is the amino acid sequence. There are 20 basic amino acids that make up proteins, and these 20 basic amino acids are the basis for biological protein post-modification, in addition, on the basis of these basic amino acids, organisms will also synthesize amino acid types derived from hydroxyproline, hydroxylysine, etc., in fireflies.

In the body, D-type amino acids are even synthesized, and these biosynthesized amino acids are collectively called "natural amino acids".

Discovery of amino acids

Aspartic acid was first discovered in 1827 by the hydrolysis of asparagine, which had been isolated from asparagus juice in 1806, by Auguste Arthur Plisson and Tienne Ossian Henry. Their original method was to use lead hydroxide, but now it is more commonly used by various other acids or bases instead.

Later, several amino acids were discovered separately, and the naming of amino acids was finally established around 1900 by hydrolysis of different proteins by chemists in the laboratory, and many different amino acids were obtained, that is, there is an amino group and a carboxyl group.

and a side chain of the structure of the substance. In 1820, glycine, which had the simplest structure, was discovered in the hydrolysate of proteins.

In 1935, the last amino acid, threonine, was discovered, and in the 1940s, more than 20 amino acids were discovered in nature. Lysine is drech-sel first derived from casein in 1889.

on the separation.

Natural amino acids.

There are 20 kinds, which are tryptophan and lysine.

Phenylalanine, methionine, threonine, valine, leucine, isoleucine, cysteine, serine, glycine, tyrosine, aspartic acid, asparagine, glutamic acid, glutamine, alanine, arginine, histidine, proline.

The basic backbone of a protein molecule is the amino acid sequence. There are 20 kinds of basic amino acids that make up proteins, and these 20 basic amino acids are the basis for the later modification of proteins.

In the body, D-type amino acids are even synthesized, and these biosynthesized amino acids are collectively called "natural amino acids". Natural amino acids are generally L-form, but there are exceptions, such as glycine. It includes both natural and biological splits.

1. Acylation reaction: reaction with nitrous acid, sulfonylation, reaction with DNFB, salt reaction.

2. Carboxyl reaction: The carboxyl group of amino acids, like other organic acids, can undergo acylation, esterification, decarboxylation and salt formation reactions under certain conditions.

Acylation reaction, esterification reaction, decarboxylation reaction, salt formation reaction.

3. Ninhydrin hydration reaction: Alpha amino acids and ninhydrin are heated together in a weakly acidic solution, and after the reaction, they are decarboxylated by water loss to form aminoninhydrinhydrone, and then react with hydrinhydrin to form purple red, and finally blue substance. This color reaction is often used for colorimetric determination of alpha amino acids and color development for chromatography analysis.

Amino acids contain both amino and carboxyl groups. Similar to hydroxy acids, amino acids can be divided into -,w-amino acids according to the different positions of amino groups attached to the carbon chain, but the amino acids obtained by protein hydrolysis are all -amino acids, and there are only more than 20 kinds, they are the basic units of proteins.

Amino acids are the basic substances that make up the proteins required for animal nutrition. Organic compounds containing alkaline amino and acidic carboxyl groups. The amino group attached to the -carbon is the -amino acid. Most of the amino acids that make up proteins are - amino acids.

Amino acids refer to carboxylic acids that contain amino groups. Various proteins in living organisms are made up of 20 basic amino acids. Except for glycomethyl acid, all of them are l amino acids, among which (proline is an l amino acid), and its structure is as shown in the figure (r group is a variable group):

Except for glycine, the carbon atoms of other protein amino acids are all asymmetric carbon closure atoms (i.e., the four substituents bonded to the carbon atoms are different), so amino acids can have stereoisomers, that is, they can have different configurations (D type and L type two configurations).[1]
