1. Collagen-an important matrix of cartilage, bone, enamel and vascular epithelium. Collagen accounts for one third of protein. Its shape is like jelly, and its function is to bond hundreds of millions of cells in the human body to form tissues (skin, blood vessel wall, cartilage, etc. ) "Jelly" makes human tissues elastic and protects cells surrounded by "Jelly" from viruses. The walls of blood vessels are bonded by this glue. When vitamin C is sufficient, "jelly" is elastic and blood vessels stretch freely like rubber bands; When vitamin C is deficient, "jelly" loses its elasticity, and blood vessels, like glass tubes, rupture as soon as they are stretched. In most cases, the red nevus on the skin is caused by the lack of vitamin C, which leads to the rupture of subcutaneous microvessels and the outflow of blood from blood vessels. Brushing bleeding is also due to the lack of vitamin C, which leads to the fragility of gingival blood vessels. When the blood vessel meets the external force of the toothbrush, it breaks on the spot, and the blood flows from the blood vessel to the mouth.
2. Promote the reaction of transforming proline into proline. Proline is one of the important components of collagen, so vitamin C can promote the formation of collagen.
3. Keep the connective tissue normal-because collagen is the intercellular substance that constitutes connective tissue.
4. Participate in redox reaction in vivo-Vitamin C can participate in the oxidation reaction of tyramine acid and some substances.
5, making adrenal steroid hormones.
6. Promote wound healing and increase sensitivity to stress such as injury and infection.
7. During infection and fever, the loss of this vitamin will also increase, so it plays an important role in the response to stimulation.
8, vitamin C detoxification;
9. Vitamin C improves myocardial function, reduces capillary fragility and increases body resistance;
10 and vitamin c fight against free radicals, which helps to prevent cancer, lower cholesterol and prevent scurvy.
