Q

describe the way in which UV, vitamin D is processed in the body and used

A
  • UV on skin causes 7-dehydrocholesterol to be converted to pre- vit D3
  • pre- vit D3 is converted into cholecaliferol (vit D3)
  • vit D3 and D2 are eaten via supplements, fish and meat
  • Vit D3 is converted in 25-hydoxyvitD3 in LIVER
  • KIDNEYS release 1alpha hydroxylase, whihc converts hydroxy vit D3 into 1,25-dihydroxyvitmain D ie calcitriol
