Calcitriol (INN), tseem hu ua 1,25-dihydroxycholecalciferol lossis 1,25-dihydroxyvitamin D3, yog cov tshuaj hormones ua kom muaj zog metabolite ntawm vitamin D nrog peb pawg hydroxyl (sau luv 1,25- (OH) 2D3 lossis yooj yim 1,25 (OH) 2D), Nws tau xub txheeb xyuas los ntawm Michael F. Holick hauv kev ua haujlwm luam tawm xyoo 1971. Calcitriol nce qib calcium (Ca2+) hauv cov ntshav los ntawm kev nce cov calcium uas nqus los ntawm lub plab mus rau hauv cov ntshav, thiab muaj peev xwm ua rau nce kev tso tawm ntawm calcium rau hauv cov ntshav los ntawm pob txha. Calcitriol (1α, 25-dihydroxy Vitamin D3) tau muab coj los ua ke los ntawm 7-dehydrocholesterol hauv tib neeg los ntawm qhov tsis-enzymatic photochemical cov tshuaj tiv thaiv nrog 290-310 nm UV teeb nyob rau ntawm daim tawv nqaij. Hydroxylation ntawm qhov tshwm sim cholecalciferol hauv lub siab ua rau 25-hydroxy Vitamin D3, tus thawj tswj hwm daim ntawv ntawm Vitamin D. Ib qhov thib ob, nruj tswj hwm hydroxylation hauv lub raum ua calcitriol. Plasma calcitriol qib ntau ntawm 10-70 pg/ml thiab cuam tshuam los ntawm ntau qhov kev noj haus thiab cov tshuaj hormones. Lub cev tseem ceeb cuam tshuam los ntawm calcitriol yog txhawm rau txhawm rau nqus cov calcium nyob rau theem ntawm cov hnyuv epithelium, thiab txhawm rau txhim kho cov pob zeb hauv av los ntawm kev txhawb nqa ncaj qha ntawm osteoblasts.
