Orgosterol is__________________?
Correct answer: C. Sterol
- A. Orgocalciferol
- B. Vitamin D2
- C. Sterol
- D. all of the above
Explanation
Ergosterol is a sterol, meaning it is a steroid alcohol with a hydroxyl group, found chiefly in fungal cell membranes. Ultraviolet radiation converts ergosterol into vitamin D2 or ergocalciferol, but ergosterol itself is not vitamin D2. The likely confusion is treating the precursor and the vitamin formed from it as identical compounds.
