What are the physiological functions of proteins, and what are the physiological functions of protei

Physiological functions of proteins: Proteins are important components of tissues and cells, such as muscles, bones and internal organs. The protoplasm of all cells is dominated by proteins, and the cell membranes and interstitium of animals are also mainly composed of proteins.

It is used to renew and repair tissue cells. Involved in the regulation of substance metabolism and physiological functions. Oxidation for energy.

1 gram of protein oxidizes in the body for energy about? 04 joules. Other features.

Such as the physiological function of multifunctional plasma proteins.

There are more than 20 kinds of amino acids that make up proteins, and only some of them can be synthesized in the body, and the rest must be supplied by food proteins. Amino acids that cannot be synthesized in the body or are synthesized too slowly must be supplied by food proteins, so they are also called "essential amino acids". Amino acids that can be synthesized by the body do not have to be supplied by food proteins, which are also called "non-essential amino acids".

Among the many amino acids used to synthesize proteins in the body, there are 8 essential amino acids that need to be fed, namely lysine, tryptophan, phenylalanine, methionine, threonine, leucine, isoleucine and valine. The more essential amino acids a food contains, the higher its nutritional value. Animal proteins such as meat, eggs, and milk all contain 8 essential amino acids, also known as high-quality proteins; The essential amino acids contained in plant proteins such as legume proteins are incomplete.

However, if the pasta is composed of corn, millet and soybean protein mixture, its nutritional value is significantly improved. This effect of mixing several proteins with low nutritional value to improve their nutritional value is also called the complementary effect of different proteins.

Protein physiological function: it constitutes an important part of the body's tissues and organs.

Protein physiological function: it constitutes an important part of the body's tissues and organs.

Protein is an important component of human tissue cells===Protein also regulates the physiological functions of the human body===Protein is the main material basis of genetic material===Protein regulates the body's water-salt metabolism and acid-base balance=== Protein also has the effect of infusion and nourishment of substances === Protein can also provide a certain amount of energy to the body.

The main physiological functions of proteins include the following four:

1. It can constitute living organisms.

2. It can maintain normal metabolism.

3. Many proteins have a certain amount of energy.

4. Protein can also be used as a kind of energy** to supply energy.

Protein is an important component of the human body, not only the human body, but also the protein of the animal body is also an important component in the animal body, which can constitute various organs and tissues. Protein, as a normal substance in tissue cells, can maintain normal metabolism. Proteins, including enzymes and hormones, are also functional substances that can assume the basic functions of living organisms.

Protein is also a kind of function, which produces energy after damage and destruction.
