2. Calcitriol - Wikipedia

   en.wikipedia.org/wiki/Calcitriol

   Calcitriol is a hormone and the active form of vitamin D, normally made in the kidney. [8] [9] [10] It is also known as 1,25-dihydroxycholecalciferol.It binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. [11]

3. Vitamin D and neurology - Wikipedia

   en.wikipedia.org/wiki/Vitamin_D_and_neurology

   One common active form is 1,25-dihydroxyvitamin D. [4] The term vitamin D in this article means cholecalciferol, ergocalciferol, 25-hydroxyvitamin D, and the active forms. The role of vitamin D is best characterized as enabling calcium absorption and regulating calcium homeostasis. Vitamin D also play a role in phosphate absorption. [5]

4. Vitamin D - Wikipedia

   en.wikipedia.org/wiki/Vitamin_D

   This condition can be caused by vitamin D, calcium or phosphorus deficiency. [84] Vitamin D deficiency remains the main cause of rickets among young infants in most countries because breast milk is low in vitamin D, and darker skin, social customs, and climatic conditions can contribute to inadequate sun exposure.

5. Calcium channel - Wikipedia

   en.wikipedia.org/wiki/Calcium_channel

   A calcium channel is an ion channel which shows selective permeability to calcium ions. It is sometimes synonymous with voltage-gated calcium channel, [1] which are a type of calcium channel regulated by changes in membrane potential. Some calcium channels are regulated by the binding of a ligand.

6. Calbindin - Wikipedia

   en.wikipedia.org/wiki/Calbindin

   Vitamin D-dependent calcium binding proteins were discovered in the cytosolic fractions of chicken intestine, and later in mammalian intestine and kidney, by researchers including Robert Wasserman of Cornell University. [10] [11] Such proteins bound calcium in the micromolar range and were greatly reduced in vitamin D-deficient

7. Vitamin D receptor - Wikipedia

   en.wikipedia.org/wiki/Vitamin_D_receptor

   The vitamin D receptor (VDR also known as the calcitriol receptor) is a member of the nuclear receptor family of transcription factors. [5] Calcitriol (the active form of vitamin D , 1,25-(OH) 2 vitamin D 3 ) binds to VDR, which then forms a heterodimer with the retinoid-X receptor .

8. Calcium metabolism - Wikipedia

   en.wikipedia.org/wiki/Calcium_metabolism

   Osteoporosis, osteomalacia and rickets are bone disorders linked to calcium metabolism disorders and effects of vitamin D. Renal osteodystrophy is a consequence of chronic kidney failure related to the calcium metabolism. A diet adequately rich in calcium may reduce calcium loss from bone with advancing (post-menopausal) age. [11]

9. 25-Hydroxyvitamin D 1-alpha-hydroxylase - Wikipedia

   en.wikipedia.org/wiki/25-Hydroxyvitamin_D_1...

   25-Hydroxyvitamin D 1-alpha-hydroxylase (VD 1A hydroxylase) also known as calcidiol 1-monooxygenase [5] or cytochrome p450 27B1 (CYP27B1) or simply 1-alpha-hydroxylase is a cytochrome P450 enzyme that in humans is encoded by the CYP27B1 gene.
