Calcium carbonate/ferrous fumarate/vitamin d

Biochem/physiol Actions Ergocalciferol (vitamin D2) is activated in vivo by hydroxylation to 25-hydroxyergocalciferol and 1&#945,25-dihydroxycalciferol. Activated Vitamin D2 molecules may be used in a wide range of studies to assess their effects

Application D-Fructose 6-phosphate (F6P) is a sugar intermediate of the glycolytic pathway that may be used to help identify, differentiate and characterize enzymes such as phosphofructokinase(s), pyrophosphate-dependent fructose-6-phosphate

Metabolite of vitamin D 3 via a single cytochrome P450-mediated hydroxylation. Further metabolized to 1&#945, 25-dihydroxy vitamin D by a second cytochrome P450-mediated hydroxylation.
