Riboflavin, also known as vitamin B 2, is a vitamin found in food and sold as a dietary supplement. [3] It is essential to the formation of two major coenzymes, flavin mononucleotide and flavin adenine dinucleotide. These coenzymes are involved in energy metabolism, cellular respiration, and antibody production, as well as normal growth and ...
Vitamin B 2 (riboflavin) for example is produced both ways. Biotransformation is mostly used for the production of riboflavin, and the carbon source starting material for this reaction is glucose. There are a few strains of microorganisms that were engineered to increase the yield of riboflavin produced.
Industrial production of B 12 is achieved through fermentation of selected microorganisms. [135] Streptomyces griseus, a bacterium once thought to be a fungus, was the commercial source of vitamin B 12 for many years. [136] The species Pseudomonas denitrificans and Propionibacterium freudenreichii subsp. shermanii are more commonly used today ...
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 is also used as an orange-red food colour additive, designated in Europe as E number E101a. [5] E106, a very closely related food dye, is riboflavin-5′-phosphate sodium salt, which consists mainly of the monosodium salt of the 5′-monophosphate ester of riboflavin. It is rapidly turned to free riboflavin after ingestion.
This article needs attention from an expert in biochemistry.The specific problem is: someone with a solid grasp of the full scope of this subject and of its secondary and advanced teaching literatures needs to address A, the clear structural issues of the article (e.g., general absence of catabolic biosynthetic pathways, insertion of macromolecule anabolic paths before all building blocks ...
It is recommended for vegans to daily eat iron-rich foods in combination with vitamin C, because vitamin C enhances iron absorption. [ 107 ] [ 108 ] Due to the low absorption rate on non-heme iron, it is recommended to eat dark leafy greens (and other sources of iron) together with sources of vitamin C. [ 109 ]
