Hello everyone, thank you for the invitation. Today I will share with you the issue of conditionally essential amino acids and some confusions about the concept of essential amino acids. If you don’t understand it yet, don’t worry. Relationship, because I will share with you next, I hope it can help everyone and solve everyone\’s problems, let\’s get started!

1. Essential The concept and classification of amino acids
Essential amino acids refer to those that the human body (or other vertebrates) cannot synthesize or the synthesis rate cannot meet the needs of the human body and must be ingested from food of amino acids. It is an amino acid that is essential for the human body (or other vertebrates) but cannot be synthesized in the body and must be supplemented from food. It is called an essential amino acid. There are eight essential amino acids for adults: lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine, and valine.
2. Structure of essential amino acids
1. Structure of essential amino acids Structural features: The structure of amino acids is composed of an amino group, a carboxyl group, a hydrogen and an R group connected to the same central C atom. The molecular formula is then C2H4O2R.
2. Structural characteristics of amino acids: Each amino acid molecule has at least one amino group and one carboxyl group; both have an amino group and a carboxyl group linked to the same carbon atom. Above; the difference between various amino acids lies in the difference in the r group (side chain group).
The molecular structure of amino acids has three major characteristics: each amino acid molecule has at least one amino group and one carboxyl group.
Each amino acid molecule has an amino group and anCarboxyl groups are linked to the same carbon atom.
The difference between various amino acids lies in the different side chain groups.
3. Names of the 8 essential amino acids
1. Essential There are eight types of amino acids, namely: lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine, and valine.
2. Essential amino acids are amino acids that the human body cannot synthesize or the synthesis rate is slow enough for the body\’s needs and needs to be obtained from food. Amino acids are very important in the human body. They can synthesize tissue proteins, convert them into carbohydrates and fats, and produce energy.
3. Lean meat, milk, eggs, and fish that are often eaten in daily life are rich in essential amino acids.
4. Concept of essential amino acids
1. Essential amino acids refer to the human body (or other vertebrates) cannot synthesize or the synthesis rate is far from meeting the needs of the body, and must be supplied by food protein.
2. For adults, there are nine essential amino acids, namely: lysine, tryptophan, phenylalanine, methionine, Threonine, isoleucine, leucine, valine, histidine. In addition, histidine is necessary for infants and young children. In addition, arginine, cystine, tyrosine, and taurine are necessary for premature infants.
5. Several types of essential amino acids
1. Essential amino acids There are 8 kinds, they are phenylalanine, methionine, lysine, threonine, tryptophan, leucine, isoleucine and valine.
2. These amino acids cannot be synthesized by the human body itself or the synthesis rate cannot meet the needs of the human body, and must be ingested from food. Lack of any essential amino acid will affect human health. Therefore, in order to maintain good health, we need to consume enough essential amino acids. In food, beans, nuts, grains, meat and fish are rich in essential amino acids.
6. Conditional amino acids are
Amino acids that cannot be synthesized in the body of animals, or can be synthesized but the rate or quantity of synthesis cannot meet the needs of animal growth, reproduction and production, and must be supplied by feed, are called essential amino acids. Current research believes that , generally there are 10 kinds of amino acids necessary for growth: lysine, tryptophan, histidine, phenylalanine, leucine, isoleucine, threonine, methionine, valine and arginine . In poultry, in addition to the above 10 types, there are 13 essential amino acids, including glycine, cystine and tyrosine.
OK, about. This concludes the content of the concepts of conditionally essential amino acids and essential amino acids. I hope it is helpful to everyone.
