Pharmacology

Ergocalciferol is a Provitamin D2 Compound.

How it is made

/Is/ the synthetic form of vitamin D. Prepared from ergosterol by UV irradiation in a suitable solvent. ... The best wavelengths for production of vitamin D2 seem to be from 275 to 300 nm ... Prepn by electron bombardment of ergosterol using longer waves...

Usually obtained from yeast which synthesizes it from simple sugars such as glucose.
