Application

7β,25-dihydroxycholesterol has been used as a substrate for 11β-Hydroxysteroid dehydrogenase (11β-HSD)-dependent metabolic studies of oxysterols in human embryonic kidney (HEK-293) cells in enzyme kinetics assay and as a standard in high-performance liquid chromatography(HPLC) for detection of dihydroxycholesterols in human plasma.

Biochem/physiol Actions

7β,25-dihydroxycholesterol is an Epstein-Barr virus-induced gene 2 (EBI2) ligand and is comparatively a weaker chemoattractant than 7α,25-dihydroxycholesterol (7α25OHC).

General description

7β,25-dihydroxycholesterol (7β25OHC) is an isomer of 7α,25-dihydroxycholesterol (7α25OHC). Its synthesis from 7-keto,25-hydroxycholesterol (7k25OHC) is catalyzed by 11β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1). 11β-Hydroxysteroid dehydrogenase type 2 (11β-HSD2) catalyzes the reverse oxidation from 7β25OHC to 7k25OHC.
