Quizplus · Accepted Answer

The main function of vitamin D is to promote calcium and phosphorus absorption, and calcium mobilization from bone. This helps in the maintenance of healthy bones and teeth. Secretion of calcitonin is not a function of vitamin D. Synthesis of 7-dehydrocholesterol is a process that occurs in the skin and is not a function of vitamin D. Synthesis of carotenoids and control of absorption of fat-soluble vitamins is not a function of vitamin D. Conversion of calcium and phosphorus to more readily absorbable compounds is not a function of vitamin D.
