Riboflavin is reversibly converted to FMN and then FAD. From riboflavin to FMN is the function of zinc-requiring riboflavin kinase; the reverse is accomplished by a phosphatase. From FMN to FAD is the function of magnesium-requiring FAD synthase; the reverse is accomplished by a pyrophosphatase. FAD appears to be an inhibitory end-product that ...
Riboflavin, or vitamin B, and flavin mononucleotide are two of the most well known flavins in the body and are used in a variety of processes which include metabolism of fat [1] and ketones [2] and the reduction of methemoglobin in erythrocytes. [3]
Flavoproteins are proteins that contain a nucleic acid derivative of riboflavin. These proteins are involved in a wide array of biological processes, including removal of radicals contributing to oxidative stress, photosynthesis, and DNA repair. The flavoproteins are some of the most-studied families of enzymes.
Whole grains can also provide essential vitamins and minerals, such as the B vitamins thiamine, riboflavin, and niacin—all of which play a key role in metabolism.
Bacteria, fungi and plants can produce riboflavin, but other eukaryotes, such as humans, have lost the ability to make it. [9] Therefore, humans must obtain riboflavin, also known as vitamin B2, from dietary sources. [14] Riboflavin is generally ingested in the small intestine and then transported to cells via carrier proteins. [9]
Flavin mononucleotide (FMN), or riboflavin-5′-phosphate, is a biomolecule produced from riboflavin (vitamin B 2) by the enzyme riboflavin kinase and functions as the prosthetic group of various oxidoreductases, including NADH dehydrogenase, as well as a cofactor in biological blue-light photo receptors.

According to Petrucci, they're also good sources of riboflavin, iron, zinc, folate, phosphorous, and vitamins A, D, B6, and B12. It's basically nature's multivitamin. It's basically nature's ...
Vitamin A acts as a regulator of cell and tissue growth and differentiation. Vitamin D provides a hormone-like function, regulating mineral metabolism for bones and other organs. The B complex vitamins function as enzyme cofactors (coenzymes) or the precursors for them. Vitamins C and E function as antioxidants. [7]
