Which of the following is an inactivated Vitamin D?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. Ergocalciferol.

  • Ergocalciferol is an inactivated vitamin D analog.
  • It is synthesized by some plants in the presence of UVB light.
  • The production of ergocalciferol was prompted by the identification of dietary deficiency, more specifically vitamin D, as the main causative factor for the development of rickets.
  • Ergocalciferol is considered the first vitamin D analog and is differentiated from cholecalciferol by the presence of a double bond between C22 and C23 and the presence of a methyl group at C24.
