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 ...

Riboflavin, Retbindin, and Riboflavin Transporters in the Retina
The retina is the most metabolically active tissue in the body. It harbors high levels of flavins due to their involvement as enzymatic co-factors in energy production. Flavins are delivered to the body via specific transporters, the ablation of which leads to riboflavin transporter deficiency (RTD) and ariboflavinosis in humans. RTD leads to embryonicXue Zhao +2 more

[36] Biosynthesis of riboflavin: Lumazine synthase and riboflavin synthase
1997Publisher Summary This chapter discusses the biosynthesis of riboflavin. 6,7-Dimethyl-8-ribityllumazine is developed as the direct biosynthetic precursor of riboflavin. The lumazine derivative is converted to riboflavin by the enzyme riboflavin synthase.

Electrochemistry of riboflavin-binding protein and its interaction with riboflavin
Bioelectrochemistry, 2009Riboflavin-binding protein (RBP, a carrier of riboflavin) plays an essential role in embryo development. Electrochemical studies of the riboflavin-RBP interactions have been so far limited to changes in polarographic and voltammetric responses of riboflavin because of lack of methods capable to detect electrochemical changes in the RBP responses.

Competitive binding assays for riboflavin and riboflavin-binding protein
Analytical Biochemistry, 1982Abstract A competitive binding procedure that can be used to determine either riboflavin or riboflavin-binding protein has been developed. Riboflavin-binding protein from chicken egg white binds tightly to DEAE-cellulose while free riboflavin does not.

Utilization of Analogues of Riboflavin by the Riboflavin-deficient Chick Embryo
The Journal of Nutrition, 1977Detailed studies of the biological activity of several analogues of riboflavin in the riboflavin-deficient chick embryo were undertaken to extend our knowledge of the comparative biochemistry of these flavins. The riboflavin-deficient eggs were produced by hens homozygous for an autosomal recessive gene (rdrd).

Publisher Summary Riboflavin is identical with vitamin B2. A high concentration of riboflavin is contained in the eyes of many fish, in certain crabs, in Hemopis sanguisuga, in Tineola bisselliella, in the malpighian tube of fireflies, in the eyes of cockroaches, and in the seminal vesicles of some bulls.

Animals and humans with tumors may display profound cachexia during the course of illness. In some instances, weight loss may be an initial manifestation of cancer, occurring before the neoplasm is widespread. Anorexia, nausea, vomiting, and diminished food intake may be important factors in contributing to the development of cachexia in far advanced ...
