Calcidiol Structure-Molecule Struture
Molecule Structure Image



Calcidiol is a prehormone that is produced in the liver by hydroxylation of vitamin D3 by the enzyme cholecalciferol 25-hydroxylase. Calcifediol is then converted in the kidneys (by the enzyme 25(OH)D-1α-hydroxylase) into calcitriol.Calcitriol binds to intracellular receptors that then function as transcription factors to modulate gene expression.It is produced in the liver and is the best indicator of the body's vitamin D stores. It is effective in the treatment of rickets and osteomalacia, both in azotemic and non-azotemic patients. Calcifediol also has mineralizing properties.It is also used in conjunction with calcium in the management and prevention of primary or corticosteroid-induced osteoporosis.
