Who told me the chemical formulas of various amino acids?

The general formula of the structure of amino acids is: ri

nh3-c-coohih

There is an amino group (NH3) and a carboxyl group (Cooh) attached to the carbon atom respectively, which is the hallmark of an amino acid.

The specific kind of amino acid is determined by the R group.

Organic matter dehydration reaction law:

1 Alcohol dehydration:

monool dehydration into alkenes or ethers; dehydration of diols into cyclic ethers (intramolecular and intermolecular); Diols are dehydrated into polymers.

2 alcohols + acids (diols + diacids).

3 Alkyds: Lactones, cycloesters, polymers are generated.

4 Amino Acids:

5 Carboxylic acids: bimolecular intermolecular chains, dibasic carboxylic acids intramolecular cyclical.

6 Nitrification:

7 Sulfonation reaction:

Inorganic dehydration reaction:

8 Intramolecular dehydration of oxygenated acids: H2CO3=H2O+CO2

Amino acids (amino

acid): A general name for a class of organic compounds containing amino and carboxyl groups, and its general formula is:

rchnh2cooh

Amino acids are explained in detail in this article on proteins.

If you want to know the chemical formula of amino acids, I can help you look it up, or you can look through the chemical reagent manual yourself.

The general structure of amino acids is as follows:

Amino acids are colorless crystals with a melting point of more than 200, which is much higher than that of ordinary organic compounds. One amino acid has four different tastes: sour, sweet, bitter and fresh. Monosodium glutamate salt and glycine are the most used umami seasonings.

Amino acids are generally soluble in water, acid solutions and alkali solutions, and insoluble or slightly soluble in organic solvents such as ethanol or ether.

Amino acids can play some of the following roles through metabolism in the human body:

1. Synthesis of tissue proteins;

2. It becomes acid, hormones, antibodies, creatine and other ammonia-containing substances;

3. Conversion into carbohydrates and fats;

4. Oxidized into carbon dioxide, water and urea to produce energy.

1. - Amino acids.

The hydrogen atom in the slip beat of the carboxylic acid molecule is replaced by an amino group to form an organic compound directly, and the amino acid refers to the amino group attached to the carboxylic acid position.

Three-dimensional structure of amino acids except glycine.

In addition, the four groups attached to the -amino acid -carbon atom are different. At this time, the 4 groups are arranged in a way from the third dimension of space.

See, there are two ways.

These two ways form shadows in the mirror with each other, and cannot overlap, and are three-dimensional isomers of each other, so that - amino acids have stereoisomers present. The two isomers are called L-type and D-type Xindanxian respectively. With the exception of glycine, the amino acids present in proteins are all L-form.

2. -Amino acids refer to amino acids bound to carbon atoms in place. The only commonly occurring naturally occurring -amino acid is -alanine, and although -alanine is often used as a component of bioactive macromolecules, -peptides are generally not found in nature.

1. Dissociation of the sexes and isoelectric points.

1. - Amino acids.

It is an amphoteric electrolyte, and the degree of dissociation depends on the pH of the solution in which it is present.

2. In a solution of a certain pH, the tendency and degree of amino acids to dissociate into cations and anions are equal, and they become facultative ions and are electrically neutral.

2. Optical properties.

1. Optical rotation: glycine in addition to plexus stockings.

In addition, other amino acids have asymmetric c atoms, and their optical rotation can be determined by polarimeter.

2. Light absorption: The R group contains tryptophan, tyrosine, and phenylalanine of the aromatic ring-conjugated double bond system.

There is light absorption in the near-ultraviolet region, so it is convenient to determine the protein content by ultraviolet spectrophotometry.

3. Important chemical reactions.

1. Ninhydrin reaction: amino acids and ninhydrin can form blue-purple compounds, which are often used as a companion solution for the quantitative analysis of amino acids.
