Vitamins

Applications Biotin Sulfone, is derivative of Biotin (B389040), which is a growth factor present in minute amounts in every living cell, and plays an indispensable role in numerous naturally occurring carboxylation reactions.

Applications Labelled Isonicotinamide is an isomeric analogue of nicotinamide and a metabolite of isonicotinic thioamide. Isonicotinamide strongly inducde apoptosis in human acute myelomonocytic leukemia cells, HL-60. References Taguchi, H.: Furi Rajik. Rin., 14, 23 (1999); Golovinski, E. et al.: Comp. Rend. Acad. Bulg.

Stability Light Sensitive, Temperature Sensitive Applications 9-cis-Retinol-d5, is the labeled analogue of 9-cis-Retinol (R252095), a metabolite of Vitamin A. References McCormick, A., et al.: J. Biol. Chem., 257(4), 1730 (1982), Buck, J., et al.: Science, 254, 1654 (1991), Napoli, J., et al.: Chem. Immunol. Immunopathol., 80, S52 (1996),

Applications Isotope Labelled analogue of Pyridoxal (P661720), one of the three natural forms of vitamin B6, along with pyridoxamine and pyridoxine. All of these forms are converted in the human body into a single biologically active form, Pyridoxal 5-phosphate (P991715). Green plants are a natural source of Pyridoxal, and its deficiency in the human body can lead to serious complications such as epilepsy and seizures. References Folch, J., et al.: J. Biol. Chem., 226, 497 (1957); Chattopadhyay, M., et al.: J. Biosci., 28, 363 (2003); Broadbent, J., et al.: J. Bacteriol. 192, 2445 (2010); Budinich, M., et al.: J. Dairy Sci., 94, 5263 (2011);

Stability Hygroscopic Applications Pyridoxol 5'-phosphate is a vitamer of Vitamin B6 complex (P991715), an enzyme cofactor in many reactions of amino acid metabolism.
