Svensk definition
Den fysiologiskt verksamma formen av D-vitamin. Den bildas framförallt i njurarna genom enzymatisk hydroxilering av 25-hydroxikolekalciferol (Kalcifediol). Produktionen stimuleras av låga blodkalciumh alter och bisköldkörtelhormon. Kalcitriol ökar absorptionen av kalcium och fosfor i tarmen, och ökar, i samverkan med bisköldkörtelhormon, resorptionen av benmassa.
Engelsk definition
The physiologically active form of vitamin D. It is formed primarily in the kidney by enzymatic hydroxylation of 25-hydroxycholecalciferol (CALCIFEDIOL). Its production is stimulated by low blood calcium levels and parathyroid hormone. Calcitriol increases intestinal absorption of calcium and phosphorus, and in concert with parathyroid hormone increases bone resorption.
