[Uses]

3-epi-25-Hydroxyvitamin D3 abbreviated as 3-epi-25(OH)D3 is a metabolite of vitamin D3 produced in the liver. 3-epi-25(OH)D3 is used as a biomarker to determine the status of vitamin D in the body. It can be also employed as an analytical standard for the quantification of 3-epi-25(OH)D3 molecules in human serum using the LC-MS/MS method.
[Uses]

The epimer metabolite of Calcifediol or 25-hydroxyvitamin D3 (C125700).
[Uses]

The labelled epimer metabolite of Calcifediol or 25-hydroxyvitamin D3 (C125700).
[General Description]

3-epi-25-Hydroxyvitamin D3 (C3-epimer) is a metabolite of vitamin D3. It is an epimer of 25-hydroxyvitamin D3 which differs only at C-3 position wherein -OH group?at C-3 carbon is in the α orientation rather than in the β orientation.
