What kind of bond is riboflavin?
Riboflavin, known as vitamin B2, belongs to the class of water-soluble vitamins with redox, fluorescence, and photosensitizing properties. Riboflavin contains a fragment of 7,8-dimethyl-10-(1′-D-ribityl) isoalloxazine with a system of conjugated double bonds that is are responsible for its photochemical properties.
Is riboflavin an ionic compound?
7,8-Dimethyl-10-[(2S,3S,4R)-2,3,4,5-tetrahydroxypentyl]benzo[g]pteridine-2,4-dione
Riboflavin/IUPAC ID
What is the functional group of riboflavin?
Riboflavin is classified as one of the water-soluble B vitamins. It is part of the functional group of flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) cofactors and is required for numerous flavoprotein-catalysed reactions.
What is riboflavin made of?
Riboflavin (vitamin B2) is a water-soluble vitamin. It is synthesized by all plants and many microorganisms, but it is not produced by higher animals. Because it is a precursor of coenzymes that are required for the enzymatic oxidation of carbohydrates, riboflavin is essential to basic metabolism.
Is riboflavin a flavonoid?
As for other flavonoids, riboflavin is known to exhibit antioxidant properties and protect tissue from oxidative damage [17–23]. Riboflavin is also important in cell repair and production and for protecting mitochondrial and other enzymes as a mitochondrial enzyme cofactor or cofactor precursor [24].
What is riboflavin soluble?
water
Riboflavin is soluble in water 0.12g per 100ml, in ethanol at . 0045g per 100ml, and it is insoluble in acetone, benzene, hexane, and chloroform.
Is riboflavin a molecule?
Riboflavin is an odd name for a molecule. It can also be reduced by the addition of a hydrogen atom onto the N on the central ring. This flexibility in oxidation-reduction reactions makes the flavin group a very important biological species in a host of biochemical pathways.
Is riboflavin an element?
Chemistry. As a chemical compound, riboflavin is a yellow-orange solid substance with poor solubility in water compared to other B vitamins.
Is riboflavin a protein?
For animal-sourced foods, free riboflavin is naturally present in foods along with protein-bound FMN and FAD….Sources.
| Source | Amount (mg) (per 100 grams) |
|---|---|
| Whey protein concentrate | 1.0 |
| Chicken eggs, fried | 0.2 (one, large) |
| Beef, cooked | 0.25-0.4 |
| Fish, cooked | 0.25-0.4 |
How is riboflavin metabolized?
Inside the gastrointestinal cells, riboflavin can either be further metabolized to flavin mononucleotide (FMN) by riboflavin kinase (RFK) or to flavin adenine dinucleotide (FAD) by FAD synthase (FADS) or transported to the bloodstream by riboflavin transporter 1 (RFVT1) and riboflavin transporter 2 (RFVT2).
Is riboflavin soluble?
Riboflavin is a water-soluble vitamin.
What kind of vitamin is riboflavin used for?
Riboflavin, also known as vitamin B2, is a vitamin found in food and used as a dietary supplement.
Where can I find the structure of riboflavin?
The structure data file (SDF/MOL File) of riboflavin is available for download in the SDF page of riboflavin, which provides the information about the atoms, bonds, connectivity and coordinates of riboflavin. The riboflavin structure data file can be imported to most of the cheminformatics software systems and applications.
How does riboflavin get released from the stomach?
In the stomach, gastric acidification releases most of the coenzyme forms of riboflavin (flavin-adenine dinucleotide (FAD) and flavin mononucleotide (FMN)) from the protein. The noncovalently bound coenzymes are then hydrolyzed to riboflavin by nonspecific pyrophosphatases and phosphatases in the upper gut.
Are there any side effects to taking riboflavin?
Side effects. In humans, there is no evidence for riboflavin toxicity produced by excessive intakes, in part because it has lower water solubility than other B vitamins, because absorption becomes less efficient as doses increase, and because what exceeds the absorption is excreted via the kidneys into urine.
