Application

3-epi-25-Hydroxyvitamin D3 is also known as 3-epi-25(OH)D3. It is a metabolite of vitamin D3 formed in the liver. 3-epi-25(OH)D3 is used as a biomarker to determine the status of vitamin D in the body.[1] It can be also employed as an analytical standard to measure the concentration of 3-epi-25(OH)D3 molecules in human serum.[2][3]

There is no effective treatment for systemic sclerosis and related fibrosing diseases. Recently the action of CYP11A1 on vitamin D(3) was shown to produce biologically active 20S-hydroxyvitamin D [20(OH)D(3)] and 20,23(OH)(2)D(3), 20,22(OH)(2)D(3), and 17,20,23(OH)(3)D(3). Because 20(OH)D(3) is noncalcemic (nontoxic) in
