一般描述
(24R)-24,25-二羟基维生素 D3（或称司骨化醇）在肾脏中产生。它是活性最高的维生素D形式之一，同时也是必需的循环维生素D3代谢产物。
应用
(24R)-24,25--二羟基维生素D3已被用于评估在原代人间充质干细胞（hMSC）的成骨细胞分化过程中，其与1α,25(OH)2D3的功能比较。
生化/生理作用
(24R)-24,25-二羟基维生素D3在钙和磷的稳态中起关键作用。(24R)-24,25--二羟基维生素D3与1α25（OH）2D3一起刺激骨代谢。
胆钙化醇是维生素D3的一种失活形式，它在经历各种水平的羟基化后可形成活性的维生素D3类似物。 1α-羟基维生素D3（骨化醇）是一种合成类似物，其可代谢为1,25-二羟胆钙化醇（维生素D3的生物活性形式）。胆钙化醇的其他类似物可由不同的羟基化产生。 24R,25-二羟基维生素D3是25-二羟基维生素D3的分解代谢产物，是发育性骨形成的推定调节剂（putative regulator）。24R,25-二羟基维生素D3是肾25-羟基维生素D3 1α-羟化酶的底物。24R,25-二羟基维生素D3是通过VDR非依赖性信号传导机制调节载脂蛋白A-I （apo A-I ）合成的内源性调节剂，也是通过Ca2 +、PLD和PLC信号传导以及通过LPA-LPA1/3-G(αi)-PI(3)K-mdm2介导的53降解起作用的 Pi诱导的细胞凋亡抑制剂。

Fundamental to understanding the way in which perturbations in the vitamin D endocrine system can affect human health is an appreciation of the steps involved in the production of the well-recognized active hormonal form, 1,25-dihydroxyvitamin D(3). Thus this paper focuses

Several studies suggest that 24,25-dihydroxyvitamin D [24,25(OH)₂D] may have an effect on bone mass and metabolism. We evaluated the relationship between serum 24,25(OH)₂D levels and bone density and bone metabolism in children with a primary bone disorder-osteogenesis imperfecta (OI). The

Ligands for the vitamin D receptor (VDR) regulate apolipoprotein A-I (apo A-I) gene expression in a tissue-specific manner. The vitamin D metabolite 24, 25-dihydroxycholecalciferol (24, 25-(OH)(2)D(3)) has been shown to possess unique biological effects. To determine if 24, 25-(OH)(2)D(3) modulates

Malfunctioning of the adenomatous polyposis coli (APC)/β-catenin signaling pathway is both an early and common event in sporadic colorectal cancer. To assess the potential of APC/β-catenin signaling pathway markers as treatable, preneoplastic biomarkers of risk for colorectal neoplasms, we conducted

CYP27B1 is a mitochondrial cytochrome P450 that catalyses the hydroxylation of 25-hydroxyvitamin D3 at the C1α-position to give the hormonally active form of vitamin D3, 1α,25-dihydroxyvitamin D3. We successfully expressed human CYP27B1 in Escherichia coli and partially purified this labile enzyme
