Question

Vitamin D3, the most abundant of the D vitamins, is synthesized from 7-dehydrocholesterol, a compound found in milk and fatty fish such as salmon and mackerel. When the skin is exposed to sunlight, a photochemical electrocyclic ring opening forms provitamin D3, which is then converted to vitamin D3 by a sigmatropic rearrangement (Section 27.5). Draw the structure of provitamin D3.
