Product Description

What is Riboflavin ?Riboflavin, regulates red blood cell growth and helps maintain a strong immune system by protecting the body from free-radical damage. Riboflavin also promotes healthy hair, skin, nails, and vision.
Without riboflavin, the other B vitamins, especially niacin (vitamin B3) and pyridoxine (vitamin B6), cannot do their job, and a host of chemical processes necessary to keep the body alive would come to a grinding halt.
You also need riboflavin to produce flavin mononucleotide and flavin adenine dinucleotide, two enzymes that help the body convert fats, carbohydrates, and proteins into energy. Without enough riboflavin, these two enzymes are unable to work together to ensure your cells can both reproduce correctly and supply the body with the fuel it needs stay alive. Function of Riboflavin1. Help to improve the quality of life
2. Treatment of Migraine
3. Promote the development and cell regeneration
4. To the skin, nails, hair, the normal growth
5. To help eliminate the mouth, lips, tongue inflammation
6. to enhance visual acuity, reducing eye fatigue Application of RiboflavinRiboflavin (vitamin B2) is the essential necessity for organism in normal living as the nutriment for infant, pregnant woman, nursing mother, patient after illness and the aged. It, involve, participates in the metabolism of carbonhydrate, protein and fat, and is the major composition of flavor protein, the transferring enzyme system of hydrogen. In clinical practice, it is applicable to perleche, glossitis, ophthalmitis, conjunctivitis, seborrhea, scrotum inflammations with proper effect, in food and feed industry, it is widely used as food and feed additive and have the Kosher Certified.

Riboflavin Usage And Synthesis

Chemical Properties	Yellow to orange/yellow crystalline powd
Uses	Nutritional factor found in milk, eggs, malted barley, liver, kidney, heart, leafy vegetables. Richest natural source is yeast. Minute amounts present in all plant and animal cells. Vitamin (enzyme cofactor).
Uses	Vitamin B2; Vitamin cofactor; LD50(rat) 560 mg/kg ip
Uses	riboflavin (Vitamin B2) is used in skin care preparations as an emollient. It can be found in sun care products as a suntan enhancer. Medicinally, it is used for the treatment of skin lesions.
Uses	Riboflavin is the water-soluble vitamin b2 required for healthy skin and the building and maintaining of body tissues. it is a yellow to orange-yellow crystalline powder. it acts as a coenzyme and carrier of hydrogen. it is stable to heat but may dissolve and be lost in cooking water. it is relatively stable to storage. sources include leafy vegetables, cheese, eggs, and milk.
Uses	Vitamin B2 (riboflavin) is produced by yeast from glucose, urea, and mineral salts in an aerobic fermentation.
Definition	ChEBI: D-Ribitol in which the hydroxy group at position 5 is substituted by a 7,8-dimethyl-2,4-dioxo-3,4-dihydrobenzo[g]pteridin-10(2H)-yl moiety. It is a nutritional factor found in milk, eggs, malted barley, liver, kidney, heart, and leafy vege ables, but the richest natural source is yeast. The free form occurs only in the retina of the eye, in whey, and in urine; its principal forms in tissues and cells are as flavin mononucleotide and flavin-adenine dinucleotide.
Brand name	Flavaxin (Sterling Winthrop).
General Description	The conflicting results were eventually found to be due,in part, to deficiencies in study animals not just of vitamin B2,but also vitamin B3 (niacin), the cause of human forms of pellagra,and/or vitamin B6 (pyridoxine), another cause of dermatitis.Likewise, treatments with vitamin B2 were inconsistentbecause the early sources of this vitamin contained otherB vitamins. Vitamin B2 was eventually isolated from eggwhites in 1933 and produced synthetically in 1935. Thename riboflavine was officially accepted in 1960; althoughthe term was in common use before then. In 1966, IUPACchanged it to riboflavin, which is in common use today.Riboflavin is synthesized by all green plants and by mostbacteria and fungi. Therefore, riboflavin is found, at least insmall amounts, in most foods. Foods that are naturally highin riboflavin include milk and other dairy products, meat,eggs, fatty fish, and dark green vegetables. Chemically, riboflavin is an N-glycoside of flavin, alsoknown as lumichrome, and the sugar, ribitol .Flavin is derived from the Latin word flavus for "yellow"because of the yellow color of its crystals and yellow fluorescenceunder UV light. Riboflavin is heat stable but easilydegraded by light. Its systematic names are 7,8-dimethyl-10-ribitylisoalloxazine and 7,8-dimethyl-10-(D-ribo-2,3,4,5-tetrahydroxypentyl)isoalloxazine.
Clinical Use	Severe riboflavin deficiency is known as ariboflavinosis, andtreatment or prevention of this condition is the only provenuse of riboflavin. Ariboflavinosis is most commonly associatedwith multiple vitamin deficiency as a result of alcoholismin developed countries. Because of the large numberof enzymes requiring riboflavin as a coenzyme, deficienciescan lead to a wide range of abnormalities. In adults seborrheicdermatitis, photophobia, peripheral neuropathy, anemia, andoropharyngeal changes including angular stomatitis, glossitis,and cheilosis, are often the first signs of riboflavin deficiency.In children, cessation of growth can also occur. As the deficiencyprogresses, more severe pathologies develop untildeath ensues. Riboflavin deficiency may also produce teratogeniceffects and alter iron handling leading to anemia.
Safety Profile	Poison by intravenous route. Moderately toxic by intraperitoneal and subcutaneous routes. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
Purification Methods	It crystallises from H2O as a yellow-orange powder in three different forms with differing amounts of H2O. It melts if placed in an oil bath at 250o, but decomposes at 280o if heated at a rate of 5o/minute. It is also purified by crystallisation from 2M acetic acid, then extracted with CHCl3 to remove lumichrome impurity. [Smith & Metzler J Am Chem Soc 85 3285 1963.] Its solubility in H2O is 1g in 3-15L depending on the crystal structure. Its solubility in EtOH at 25o is 4.5mg in 100mL. Store it in the dark because it is decomposed to lumichrome by UV light.
