5-Cholesten-3-beta, 7-alpha-diol

7α-Hydroxycholesterol (566-26-7) is a metabolite resulting from the action of cholesterol 7α-hydroxylase on cholesterol. 7α-Hydroxycholesterol is the first intermediate and a rate limiting step in the major pathway for bile acid synthesis in humans.A pro-inflammatory mediator which upregulates production of CCL2 and MMP9 in macrophages and may promote progression of atherosclerosis.2,3Possible biomarker for cellular lipid peroxidation.4
