Other Name: Riboflavin
Status: Yellow and white powder
A vitamin which widespread in nature. It is a necessary nutrient to mammal, The coenzyme form is flavin mononucleotide and flavin adenine dinucleotide.
Status: One of the essential vitamin to human body, one of the member of vitamin B.
Vitamin B2 molecule structure
Vitamin B2 also called riboflavin slightly soluble in water, in a neutral or acidic solution, heating is stable. For the body yellow enzymes prosthetic consist part (yellow enzyme in biological oxidation reduction plays hand hydrogen effect), when the lack of, will affect the body's biological oxidation, make the metabolic appear disorder. The pathological changes were much performance is the mouth, eye and genitalia parts of the inflammation, such as angular stomatitis, cheilitis, glossitis, eye conjunctivitis and scrotum inflammation, etc., so this product can be used for the prevention and treatment of these diseases. The storage of vitamin B2 is very limited, so every day provide from diet. The two features of vitamin B2 is the main reasons caused it loss (1) may be light damage; (2) in alkaline solution can be destroyed by heating.
Water soluble vitamins, but slightly soluble in water, at 27.5 centigrade for 12mg/100mL solubility. Soluble in sodium chloride solution, soluble in dilute sodium hydroxide solution, readily soluble in alkaline solution, in strong acid solution stability. Heat resistance, oxidation resistance. Light and UV radiation caused by irreversible decomposition.
Mainly associated with vitamin B2 molecule isoalloxazine 1, 5 N existing active conjugated double bonds, which can be used as hydrogen donor, but also can be used as hydrogen carrier. In the human body according to flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) of two forms involved in redox reactions, plays the role of hydrogen delivery, is the number of important COA reductase in body.
Mainly involved in the biochemical reaction of respiratory chain energy, amino acid, lipid oxidation, purine converted to uric acid, aromatic hydroxylation, protein and some hormone synthesis, iron transport, storage and mobilization, involved in folate, with multiple aldehyde, nicotinic acid metabolism etc.
1. In vivo biological oxidation and energy metabolism, and connect with carbohydrate, protein, nucleic acid and fat metabolism, can improve the utilization of body to protein, promote the growth and development, the maintenance of skin and cell membrane integrity. With the protection of the skin of hair follicles and sebaceous glands mucous membrane function.
2. Involved in cell growth and metabolism, it is the body tissue metabolism and the necessary nutrients of repair, such as strengthening the function of liver.
3. The involvement of vitamin B6 and nicotinic acid metabolism, B vitamins are coordinating role as a model. FAD and FMN as a cofactor involvement of tryptophan is converted to niacin, it is a process of vitamin B6 turned into pyridoxal phosphate.
4. It related to iron uptake, storage and mobilization.
5. It has antioxidant activity, may be related to glutathione reductase enzyme flavin.
|In the diet of most of the vitamin B2 in the flaying mononucleotide (FMN) and flaying adenine dinucleotide (FAD) and protein binding in the presence of coenzyme form. After into the stomach, under the action of gastric acid, and separation with protein, in the upper gastrointestinal tract into free vitamin B2, in the upper small intestine absorption. When the intake of large, and often have higher concentrations, but the physical storage of vitamin B2 limited capacity, more than the threshold kidney through the urinary system, in order to free the form of excretion, the daily body tissue demands needs to be necessary for the food supply.|
|In 1879, a famous English chemist Bruce found that milk whey in the upper there is a yellow-green fluorescent pigment, they used a variety of methods to extract, trying to find its chemical nature, without success. In several decade years, although many scientists from different sources in both plants and animals found that the yellow substance, but are not recognized. In 1933, American scientist Gorba G get 18 mg of this substance from more than 1000 kilograms of milk, then because of its molecular formula has a ribitol, people named riboflavin.|
|1. The promotion of development and cell regeneration;||2. promoting skin, nails, hair growth;|
|3. To help prevent and eliminate the mouth, lips, tongue and skin inflammation, collectively referred to as oral genital syndrome;|
|4. Improve vision, reduce eye fatigue;||5. Affect the body' s absorption of iron;|
|6. Combined with other materials together, thus affecting the biological oxidation and energy metabolism.|
|Mechanism of action:|
|Vitamin B2 is the main physiological function as a cofactor to promote metabolism. Riboflavin and phosphoric acid and a protein binding to become yellow enzyme. This enzyme is also called dehydrogenate, important to be very mediated hydrogen atom transfer on glucose, lipid and amino acid metabolism are very important. It is the essential factor of much animal and microbial growth.|
|Vitamin B2 is generated with a specific protein binding yellow enzyme. Yellow enzyme in the metabolism of hydrogen to play a passing role, participating in the breathing process.|
|Rich in vitamin B2 milk|
Vitamin B2 is a water-soluble vitamin, easily digested and absorbed, discharged with in vivo and may vary with protein loss and increase / decrease; it does not accumulate in the body, so often supplement according to food or nutritional supplements.
|Milk and dairy products, animal liver and kidney yolk eel spinach carrot brewing yeast laver and mushroom eggplant celery oranges citrus orange.|
|Adults daily eat 50g animal liver can meet the needs;|
Adult daily eat about 100g soybean can meet the needs;
Adult day to eat 3 lettuce can meet the needs;
Adult daily eat 3~4 mushroom can meet the needs
|One, used in the treatment of angina pectoris|
|The risk of coronary heart disease, myocardial ischemia and angina person, if take vitamin B275 mg, 3 times a day, after a month treatment, can make the angina pectoris frequency reduced, or even disappear. This is because vitamin B2 can improve the blood supply of the heart.|
|Two, for the prevention and treatment of migraine|
|The researchers of Belgium and Luxembourg found, large dose of vitamin B2 can make the occurrence of migraine frequency reduced, episode duration shortened. Migraine headaches are due to brain cells caused by reduced energy reserve. And vitamin B2 can improve cerebral mitochondria potential. Therefore, a once daily dose of 400 mg vitamin B2, can be effective in the treatment of migraine.|
|Three, help to improve the quality of sexual life|
|Research shows, the human body contains vitamin B2, the number and the quality of vitamin B2 is closely related to sexual life. When the body lacks vitamin B2, human organ cavity mucous layer will be damaged, appear thinner mucosa, mucosa injury and micro vascular rupture. For women this damage was more severe. Females lack of vitamin B2 can be performed for the vagina, vaginal mucosa hyperemia, broken, resulting in loss of libido, sex and sexual discomfort. When this case appear, every time of oral vitamin B2, 10 mg, 3 times daily.|
|Four, prevention and treatment of cancer|
|Scientists study found that, if lack of vitamin B2, can be enhanced by chemical carcinogen function. So in daily life and more supplements vitamin B2 can prevent cancer. Vitamin B2 supplementation of commonly used quantity: each 10 mg, orally 3 times daily.|
Vitamin B2 supplementation, can also be used for food, eat more foods rich in vitamin B2. Such as milk and dairy products, animal liver, kidney, egg yolk, eel, carrots, mushrooms, seaweed, orange, tangerine, orange.
