Constitute the body and repair tissues
The body's nerves, muscles, internal organs, blood, bones and even nails hair contain but plate. The growth and development of the body, the renewal of aging tissues, and the repair of tissues after injury are all dependent on protein. Therefore, each person must consume a certain amount of protein every day as the material for constituting and repairing tissues.
Human protein is always in a dynamic balance between synthesis and decomposition, and about 3% of protein is involved in renewal every day.
The main raw material for enzymes and hormones
The metabolism of the organism is achieved through numerous chemical reactions, which are catalyzed by various enzymes. Enzymes are proteins that are involved in various life activities in the internal environment of the body, such as muscle contraction, blood circulation, respiration, digestion, nerve conduction, sensory functions, energy exchange, information processing, genetics, growth and development, and prevention and control. Without enzymes, life would not exist. Some of the hormones that regulate physiological functions are also attended by proteins and peptides.
Enhance the immunity of the body
When the body is attacked by some external harmful factors, the body can produce a corresponding antibody and react with it specifically to eliminate its effect on the normal organism, i.e. immune response. There are many kinds of antibodies, all of which are immunoglobulins, or antibody globulins, and these globulins can improve the body's resistance.
Supply of energy
Each 1g of protein can release 16.7kj of calories, and 10-15% of the body's daily caloric needs come from protein, but providing energy is not the main function of protein; only when carbohydrates and fats are not functional enough, protein provides calories to the body.
Oxygen transport
The oxygen required in the metabolic process of the body and the carbon dioxide produced are transported by hemoglobin in the blood, which is a complex of globulin and hemoglobin. Certain substances in cellular metabolic processes also tend to form complexes with proteins, such as fatty acids, cholesterol, and phospholipids in the blood that bind to proteins to form lipoproteins.
Maintaining the elasticity of the skin
Collagen is a component of the body's connective tissue and actively participates in cell migration, differentiation and value-added, with associative and nutritional functions, as well as support and protection. The collagen content in human skin is as high as 71.9%, and a long-term lack of protein can lead to a decrease in the physiological function of the skin, making the skin lose its luster, appearing to be unstable and less elastic.
