The biosynthesis of riboflavin requires 1 equivalent of GTP and 2 equivalents of ribulose phosphate. The first committed reactions of the convergent pathway are catalyzed by GTP hydrolase II and 3,4-dihydroxy-2-butanone 4-phosphate synthase.

The metal chelates of riboflavin and riboflavin monophosphate
Journal of Inorganic and Nuclear Chemistry, 1973Abstract The metal chelates of riboflavin and its monophosphate ester, with bivalent transitional metal ions, Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) in a 1:1 mole ratio, have been studied potentiometrically at 35°C and μ = 0·1.

Riboflavin, sometimes called vitamin B2, is essential for the intermediary metabolism of carbohydrates, amino acids, and lipids. It is widely distributed in many foods, including green, leafy vegetables, and meat and dairy products. It is water soluble and its enteric absorption is facilitated by specific transporters after the vitamin is hydrolyzed in

The biosynthesis of one riboflavin molecule requires one molecule of GTP and two molecules of ribulose 5-phosphate. The imidazole ring of GTP is hydrolytically opened, yielding a 4,5-diaminopyrimidine that is converted to 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione by a sequence of deamination, side chain reduction, and dephosphorylation ...

It is with apprehension that one reports any new form of treatment for psoriasis. However, the results with a new form of riboflavin have been so encouraging in a limited number of cases that this preliminary report is issued. Relatively recent discoveries on the mode of action of riboflavin have suggested its use in some of the scaly skin diseases of

Riboflavin deficiency diminishes the rate of growth of spontaneous tumors in experimental animals but enhances the carcinogenicity of specific drugs such as the azo dyes, which are degraded by a microsomal hydroxylase system requiring riboflavin. Human esophageal cancer has been epidemiologically associated with riboflavin deficiency, but the precise ...

Bioengineered riboflavin in nanotechnology
Biomaterials, 2016Riboflavin (RF) is an essential water-soluble vitamin with unique biological and physicochemical properties such as transporterspecific cell internalization, implication in redox reactions, fluorescence and photosensitizing. Due to these features RF attracted researchers in various fields from targeted drug delivery and tissue engineering to ...
