protein is the material basis of life. Without protein, there would be no life. The more complex the organism structure is, the more diverse its protein types and functions are. Its main biological functions are:

(1) Catalytic and regulatory ability

Some protein are enzymes, which catalyze the metabolic reaction of substances in organisms.

Some protein are hormones, which have certain regulatory functions. For example, insulin regulates glucose metabolism and signal transduction in vivo is often mediated by some protein.

(2) Transport function

Some proteins have transport function, such as hemoglobin is a tool for transporting oxygen and carbon dioxide, and serum albumin can transport free fatty acids and bilirubin.

(3) Contraction or movement function

Some protein endows cells and organs with the ability to contract, which can make them change shape or move. Such as skeletal muscle contraction depends on actin and myosin.

(4) Defensive functions, such as immunoglobulin, can resist foreign harmful substances and protect the body.

(5) Nutrition and storage functions such as ferritin can store iron.

protein? -the material basis of life

protein is an important component of all cells and tissues in the human body. All important components of the organism need protein's participation. Generally speaking, protein accounts for about 18% of the total mass of the human body, and the most important thing is that it is related to life phenomena.

protein is the material basis of life, an organic macromolecule, a basic organic substance that constitutes cells, and the main undertaker of life activities. There is no life without protein. Amino acids are the basic building blocks of protein. It is a substance closely related to life and various forms of life activities. Protein is involved in every cell and all important parts of the body. Protein accounts for 16%~2% of human body weight, that is, an adult weighing 6kg has about 9.6~12kg of protein in his body. There are many kinds of protein in human body, with different properties and functions, but they are all composed of more than 2 Amino acid in different proportions, and they are constantly metabolized and updated in the body.

protein and Health

protein was discovered by Dutch scientist GerPark Jung Su mulder in 1838. He observed that living things could not exist without protein. Protein is an extremely important polymer organic matter in living organisms, accounting for 54% of the dry weight of human body. Protein is mainly composed of amino acids, and various types of protein are formed due to different combinations and arrangements of amino acids. It is estimated that there are more than 1, kinds of protein in human body. Life is an advanced form of material movement, which is realized through protein, so protein has extremely important biological significance. The growth, development, movement, heredity, reproduction and all other life activities of the human body are inseparable from protein. Life movement needs protein and protein.

Some physiologically active substances in human body, such as amines, neurotransmitters, polypeptide hormones, antibodies, enzymes, nuclear proteins and proteins on cell membrane and blood, are inseparable from protein, which plays an extremely important role in regulating physiological functions and maintaining metabolism. The composition of muscles in the human exercise system and the metabolism of muscles in the process of contraction, doing work and completing movements are all related to protein. Without protein, physical exercise is impossible.

In biology, protein is interpreted as a polypeptide formed by amino acids linked by peptide bonds, and then linked by polypeptides. To put it bluntly, it is the scaffold and main substance that constitutes human tissues and organs, and it plays an important role in human life activities. It can be said that there would be no life activities without protein. Protein mainly exists in lean meat, eggs, beans and fish in daily diet. Protein deficiency: Adults: muscle wasting, decreased immunity, anemia, and edema in severe cases. Minors: growth and development stagnation, anemia, poor intellectual development and poor vision. Protein overdose: protein can't be stored in the body, and it can't be absorbed by the body. Excessive intake of protein will lead to protein poisoning and even death due to metabolic disorders.
