Hello everyone, today I will share with you some knowledge points about amino acids and analysis of what amino acids include. If you all understand it, you can ignore it. If you are not sure, you can Take a look at this article, I believe there is a high probability that it can solve your problem, let’s take a look together!

1. What is the definition of amino acids?
The definition of amino acids is the basic unit that constitutes proteins. Proteins are formed by linking amino acids through dehydration and condensation reactions. The type and order of amino acids determine the diversity and function of proteins. There are 20 common amino acids, which can form countless different proteins through different combinations and links, thereby participating in various life activities of the human body.
2. What are the components of amino acids
1. What are amino acids? It is mainly composed of 4 elements: C, H, O, and N. Some also contain two elements: P and S. Its structure is: it contains at least one amino group (-NH2) and one carboxyl group (-COOH), and both have an amino group. attached to the same carbon atom as a carboxyl group.
2. Amino acids are the basic substances that constitute the protein required for animal nutrition. They are organic compounds containing a basic amino group and an acidic carboxyl group. The amino group is usually connected to α -on carbon. Amino acids are the basic units of protein. When the human body metabolizes them, amino acids can be synthesized into proteins and converted into carbohydrates, fats, etc. From a biological point of view, amino acids are the basic structure of living organisms. Amino acids play many important roles through metabolism in the body. First, they synthesize tissue proteins, but also synthesize hormones, antibodies, creatine and other ammonia-containing substances. They are important for enhancing immunity, Strengthening your body helps a lot.
3. What do amino acids include
Amino and carboxyl groups. Amino acids are organic compounds containing basic amino groups and acidic amino groups. Amino acid molecules contain amino and carboxyl functional groups. Amino acids are colorless crystals and are the basic substances of animal nutritional protein.
Four. Ten kinds of amino acids
There are many amino acids that make up the human body. Including tryptophan, methionine, threonine, valine, lysine, histidine, leucine, isoleucine, alanine, phenylalanine, cystine, cysteine, Arginine, glycine, serine, tyrosine, glutamic acid, aspartic acid, proline, hydroxyproline, citrulline, ornithine, etc. These amino acids widely exist in nature. There are eight kinds of amino acids that cannot be synthesized in the human body and must be provided by food. They are called essential amino acids. These eight kinds of essential amino acids are tryptophan, threonine, methionine, valine, lysine, leucine, and isosine. Leucine and phenylalanine, and the others are non-essential amino acids. Amino acids are important structures for protein synthesis in the body.
5. What do amino acids look like
Colorless crystals, melting point Extremely high, generally above 200℃. Different amino acids have different tastes, some are tasteless, some are sweet, and some are bitter. The monosodium salt of glutamic acid has an umami taste and is the main component of MSG. The solubility of various amino acids in water varies greatly, and they can be dissolved in dilute acids or alkalis, but cannot be dissolved in organic solvents. Alcohol usually precipitates amino acids out of their solutions.
Sixth, what are the 18 kinds of amino acids
1. 18 kinds Amino acids: glycine (GLY), leucine (LEU), methionine (MET), tyrosine (TYR), histidine (HIS), threonine (THR), alanine (ALA), isoleucine Acid (ILE), tryptophan (TRY), cystine (CYS), lysine (LYB), aspartic acid (ASP), valine (VAL), phenylalanine (PHE), proline acid (PRO), serine (SER), glutamic acid (GLU), arginine (ARG)
2. Eighteen amino acids refer to glycine, arginine Amino acid, leucine, valine, alanine, serine acid, proline, isoleucine, phenylalanine, lysine, threonine, methionine, tryptophan, histidine, tyrosine Acid, aspartic acid, cysteineAcid, glutamic acid; the seventeen amino acids have removed proline, because proline is one of the components of plant protein
OK, this is the end of this article Ending, I hope it helps everyone.
