The Six Function Of Human Body Protein

In the human body, physiological functions of proteins in six aspects:

1)Composition and repair the body material of various tissues and cellsNerves, muscles, organs, blood, bones, etc., even including the scalp, nails contain proteins in vitroQuality, these cells are constantly updated every day.Therefore, the human body must consume a certain amount of protein, as the material of composition and tissue repair.

2) make enzymes, hormones and antibodies
The body's metabolism is actually accomplished by chemical reaction, in the human body in the process of chemical reaction, can not do without the catalysis of enzymes, if there is no enzyme, about life, these each has its special function of the enzyme, is made up of protein.In addition, some regulate hormone and insulin physiological function, and improve the ability of the body to son antibodies protect the body from pathogenic microorganisms, is made up of protein as the main raw material.

3) maintain normal plasma osmotic pressure, is the material exchange between plasma and tissue balance
If long-term lack of dietary protein, will reduce the content of plasma protein, especially albumin, blood in the water will be too much into the surrounding tissue, benign edema cause clinical nutrition.

4) to supply the body energyUnder the condition of normal diet, the body can be completed the main function and the rest of the protein, the oxidation decomposition into energy.However, from the whole body is concerned, this aspect of protein function is negligible.

5) to maintain the body's acid-base balance
Tissues in the body cells must be in proper ph range, to complete the normal physiological activities.The body of this capacity to maintain acid-base balance is through the lungs, kidneys and blood buffer system.Protein buffer system is an important part of the blood buffer system, thus proteins in maintaining the body acid-base balance plays a very important role.

6) transport oxygen and nutrients
Hemoglobin can carry oxygen to all parts of the body, for the use of tissue cell metabolism.The body there are many nutrients must be combined with a specific protein, as a carrier to operate, such as ferritin, calcium binding protein, such as retinol proteins are such
