Efficacy and function of vitamin C Ⅱ
1, which has the advantage of anti-oxidation: vitamin C can eliminate free radicals that lead to skin oxidation.
These free radicals are also the main cause of skin aging.
Therefore, vitamin C can delay aging, prevent wrinkles and spots from appearing in advance, and achieve the effect of delaying aging.
2. It has the effect of whitening and removing spots: Vitamin C can also inhibit the formation of melanin on the skin, dilute the spots on the skin, whiten the skin and improve the brightness of the skin.
3, can enhance skin tolerance: vitamin C can improve metabolic rate, improve skin immunity, enhance skin cells, increase skin elasticity, and enhance skin resistance to sunlight and ultraviolet rays.
4. It has the advantage of promoting collagen synthesis: the dermis of the skin is rich in collagen, which is also an important part of supporting the skin.
However, with the increase of age and the influence of external factors, collagen in the skin is constantly losing.
Vitamin C supplementation can accelerate the synthesis of collagen and prevent wrinkles from appearing prematurely.
5, has the advantage of accelerating wound healing: if there is a wound on the skin, using vitamin C can also make the wound recover faster and make the skin recover as soon as possible.
There are also scars on the skin.
Vitamin c can also play a role in desalination.
The efficacy and role of vitamin C Vitamin C is a common abbreviation of vitamin C.
Vitamin C (ascorbic acid), also known as L- ascorbic acid, is a water-soluble vitamin.
So what are the functions and functions of vitamin C? Let's get to know each other.
Efficacy and function of vitamin c
1. Prevention of arteriosclerosis
Vitamin C can promote the hydroxylation and excretion of cholesterol, prevent cholesterol from depositing on the inner wall of arteries, and play a role in preventing arteriosclerosis.
Cancer prevention
The antioxidant effect of vitamin C can resist the damage of free radicals to cells and prevent cell variation. Prevent nitrite and secondary amine from forming strong carcinogen nitrosamine.
In addition, vitamin C promotes the synthesis of collagen and helps to prevent the spread of cancer cells.
3. Prevent gum bleeding
Many people have encountered gum bleeding. There are many reasons for gum bleeding, which may be due to poor dental health or lack of vitamin C. If it is caused by lack of vitamin C, it is even more necessary to supplement it, which is conducive to protecting dental health and improving gingival atrophy.
Whitening spot
Vitamin C can inhibit the formation of arginase, indirectly inhibit the formation of melanin, reduce the precipitation of melanin, dilute melanin, and then play a role in whitening and lightening spots.
In addition, vitamin C can also increase the collagen of the skin and dilute wrinkles.
5. Synthesis of Collagen
The synthesis of collagen needs vitamin C, so the lack of VC prevents the normal synthesis of collagen, which leads to the disorder of cell connection.
The human body is composed of cells, which are connected by intercellular substance, and the key component of intercellular substance is collagen.
Collagen accounts for 1/3 of the protein of the body, which generates connective tissue and constitutes the bones of the body.
Such as bones, blood vessels and ligaments. , determine the elasticity of the skin, protect the brain, and contribute to the healing of human trauma.
6. Enhance immunity
Vitamin C can enhance immunity because it can enhance the activity of white blood cells and antibodies in immune cells, stimulate the human body to produce active substances to promote immunity, eliminate viruses and reduce the loss of white blood cells.
What are the functions and functions of vitamin C?
What are the functions and functions of vitamin C? Speaking of vitamin C, everyone knows that it is an essential trace element for human body. Many foods are rich in vitamin C, which is also very important to the human body. What are the functions and functions of vitamin C? Let's have a look.
What are the functions and functions of vitamin C 1?
1. Synthesis of Collagen
The synthesis of collagen needs vitamin C, so the lack of VC leads to the abnormal synthesis of collagen, which leads to the disorder of cell connection.
The human body is composed of cells, which are connected by intercellular substance, and the key component of intercellular substance is collagen.
Collagen accounts for 1/3 of the protein of the body, which generates connective tissue and constitutes the bones of the body.
Such as bones, blood vessels and ligaments. , determine the elasticity of the skin, protect the brain, and contribute to the healing of human trauma.
Second, the treatment of scurvy
The strength of vascular wall has a great relationship with VC.
Microvessel is the smallest of all blood vessels, and its wall may be only one cell thick. Its strength and elasticity are determined by collagen, which is responsible for connecting cells and has the function of cement.
When VC is insufficient in the body, microvessels are easy to rupture and blood flows to adjacent tissues.
When this happens on the skin surface, it will produce congestion and cyanosis; When it happens in the body, it can cause pain and joint swelling.
In severe cases, bleeding of stomach, intestine, nose, kidney and periosteum may occur, and even death may occur.
Third, prevent gingival atrophy and bleeding.
A healthy chewing gum tightly wraps every tooth.
Gingiva is soft tissue, which is prone to atrophy and bleeding when lacking protein, calcium and VC.
Vitamin c is slightly acidic. As a micronutrient, it is ingested into the body. After being dissolved and digested in the body, its acidity and alkalinity have little effect on the human body, so it is not necessary to pay too much attention to its acidity and alkalinity.
Vitamin C helps to consolidate cell tissue, help to synthesize collagen, strengthen bones and teeth, and prevent gum bleeding. Long-term use is harmless and beneficial to teeth and gums.
Fourth, prevent arteriosclerosis.
It can promote the excretion of cholesterol, prevent cholesterol from depositing on the inner wall of arteries, and even dissolve the deposited atherosclerotic plaques.
Verb (abbreviation for verb) antioxidant
It can protect other antioxidants, such as vitamin A, vitamin E, unsaturated fatty acids, etc., and prevent free radicals from harming human body.
Six, the treatment of anemia
It can reduce ferric iron which is difficult to be absorbed and utilized to ferrous iron, promote the absorption of iron in intestine, improve the utilization rate of iron in liver, and help to treat iron deficiency anemia.
Seven, cancer prevention
Rich collagen helps to prevent cancer cells from spreading; The antioxidant effect of VC can resist the damage of free radicals to cells and prevent cell variation; Prevent nitrite and secondary amine from forming strong carcinogen nitrosamine.
Someone once dissected a patient who died of cancer and found that the VC content in the patient was almost zero.
Eight. defencive function
In human life activities, glutathione and enzymes are very important to ensure the integrity of cells and normal metabolism.
Because most mammals can synthesize vitamin C through the liver, there is no problem of deficiency. However, a few animals, such as humans, primates and groundhogs, cannot synthesize themselves and must be ingested through food and drugs.
Nine, enzyme
Glutathione is a short peptide composed of glutamic acid, cystine and glycine, which has redox effect in the body.
It exists in two forms, namely oxidation type and reduction type, and reduction type plays an important role in ensuring the integrity of cell membrane.
VC is a strong antioxidant, which reduces oxidized glutathione to reduced glutathione through its own oxidation, thus playing an antioxidant role.
Enzymes are catalysts for biochemical reactions, and some enzymes need free sulfhydryl (-SH) to keep their activity.
VC can reduce disulfide bond (-S-S) to -SH, thus improving the activity of related enzymes and playing an antioxidant role.
Ten, improve human immunity.
White blood cells are rich in VC, and when the body is infected, the VC in white blood cells decreases sharply.
VC can enhance the chemotaxis and deformability of neutrophils and improve their bactericidal ability.
Promote the generation of lymphocytes and improve the body's ability to identify and kill foreign cells and malignant cells.
Participate in the synthesis of immunoglobulin.
Improve the activity of complement esterase in CI and increase the production of complement CI.
Promote the production of interferon, interfere with the transcription of virus mRNA, and inhibit the proliferation of virus.
Eleven, improve the body's emergency ability.
Abnormal stimuli to the human body, such as severe pain, cold, lack of oxygen, strong mental stimulation, etc., will trigger a state of tension against abnormal stimuli.
This state is accompanied by a series of organisms, including sympathetic nerve excitement, adrenal medulla and increased secretion of corticosteroids.
Adrenaline and norepinephrine secreted by adrenal medulla are converted from tyrosine, which requires VC.
What is the function and function of vitamin C 2?
1. How about taking a vitamin C every day?
In life, the average adult needs 100mg of vitamin C every day. If our body needs less than 500mg/ day, it will definitely be harmful to our health.
But you all know that drugs have three kinds of toxicity. Don't say that drugs have side effects, even eating too much will support and induce pancreatitis and gastrointestinal dysfunction.
If you take too much vitamin C in a short time, it may cause increased urine output, rash and skin edema. Taking too much vitamin C for a long time may even increase the risk of kidney calculi and bladder stones. Moreover, vitamin C can also cause the increase of uric acid, megaloblastic anemia, hemolysis and other adverse reactions.
Second, the harm of taking too many vitamin C tablets?
Excessive consumption of vitamin C tablets in life may have a more direct impact, which may be gastrointestinal reaction.
The food that people eat is always digested and absorbed by the stomach.
Of course, vitamin C is no exception. Excessive use will increase the burden on the stomach, but it will affect the health of the stomach.
After taking it for a long time, if you have vomiting or stomachache, it is a sign that your stomach has changed and you should stop taking it.
No matter what we usually eat, or what kind of nutrients we supplement, we must have a degree, and we can't just eat vitamin C supplements.
Third, the benefits of vitamin C to the human body
In daily life, vitamin C can promote the utilization of iron, calcium and folic acid, and transform them into nutrients needed by our human body, and finally improve our immunity.
Studies have shown that vitamin C also has the function of whitening and sun protection, which is a topic collected by many women who love beauty. A certain amount of vitamin C can improve facial pigment and protect skin.
Vitamins are widely used, from children to adults, but remember not to replace fresh vegetables and fruits with vitamin C, otherwise vitamin C will have no effect.
So much for the introduction of the efficacy and function of vitamin C. Thank you for taking the time to read this website. Don't forget to check the efficacy and function of vitamin C and its contraindications.
