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.--PubChem [HMDB] (1a,3b,5Z,7e)-9,10-Secocholesta-5,7,10(19)-triene-1,3,25-triol (1alpha,3beta,5Z,7e)-9,10-Secocholesta-5,7,10(19)-triene-1,3,25-triol (1S,3R,5Z,7e)-9,10-Secocholesta-5,7,10-triene-1,3,25-triol (1α,3β,5Z,7e)-9,10-secocholesta-5,7,10(19)-triene-1,3,25-triol (3b,5Z,7e)-9,10-Secocholesta-5,7,10(19)-trienetriol (5Z,7e)-(1S,3R)-9,10-Secocholesta-5,7,10(19)-triene-1,3,25-triol 1-a-25-Dihydroxyvitamin D3 1-alpha-25-Dihydroxyvitamin D3 1-alpha,25-Dihydroxyvitamin D3 1-α-25-dihydroxyvitamin D3 1,25 Dihydroxycholecalciferol 1,25-DHCC 1,25-Dihydroxycholecalciferol 1,25-Dihydroxyvitamin D 1,25-Dihydroxyvitamin D3 1a,25-(OH)2D3 1a,25-Dihydroxycholecalciferol 1a,25-Dihydroxyvitamin D3 1a,25(OH)2D3 1alpha,25-Dihydroxycholecalciferol 1alpha,25-Dihydroxyvitamin D3 1alpha,25(OH)2D3 1α,25-dihydroxycholecalciferol 1α,25-dihydroxyvitamin D3 1α,25(OH)2D3 25-Dihydroxycholecalciferol 5-{2-[1-(5-hydroxy-1,5-dimethyl-hexyl)-7a-methyl-octahydro-inden-4-ylidene]-ethylidene}-4-methylene-cyclohexane-1,3-diol Calcijex Calcitriolum Decostriol Dihydroxyvitamin D3 Ro 21-5535 Rocaltrol Silkis Soltriol Topitriol Toptriol C27H44O3 416.6365 416.329045274 (5E)-5-{2-[(4Z)-1-(6-hydroxy-6-methylheptan-2-yl)-7a-methyl-octahydro-1H-inden-4-ylidene]ethylidene}-4-methylidenecyclohexane-1,3-diol (5E)-5-{2-[(4Z)-1-(6-hydroxy-6-methylheptan-2-yl)-7a-methyl-hexahydro-1H-inden-4-ylidene]ethylidene}-4-methylidenecyclohexane-1,3-diol 32222-06-3 CC(CCCC(C)(C)O)C1CCC2\C(CCCC12C)=C/C=C1\CC(O)CC(O)C1=C InChI=1S/C27H44O3/c1-18(8-6-14-26(3,4)30)23-12-13-24-20(9-7-15-27(23,24)5)10-11-21-16-22(28)17-25(29)19(21)2/h10-11,18,22-25,28-30H,2,6-9,12-17H2,1,3-5H3/b20-10-,21-11+ GMRQFYUYWCNGIN-NGHQTVFFSA-N belongs to the class of organic compounds known as vitamin d and derivatives.
