How does sunlight help the body synthesize and activate vitamin D?
What will be an ideal response?
To make vitamin D, ultraviolet rays from the sun hit a precursor in the skin and convert it to previtamin D3, which is converted to vitamin D3 with the help of the body’s heat. To activate vitamin D—whether made in the body or consumed from the diet—two hydroxylation reactions must occur. First, the liver adds an OH group, and then the kidneys add another OH group to produce the active vitamin. As you might expect, diseases affecting either the liver or the kidneys can interfere with the activation of vitamin D and produce symptoms of deficiency.
