Identification
Common Name7a-Hydroxycholesterol
ClassSmall Molecule
Description7a-Hydroxycholesterol is an oxysterol and can serve as a biomarker for lipid peroxidation. Products of cholesterol oxidation accumulate within atherosclerotic plaque and have been proposed to contribute to inflammatory signalling in the diseased artery. 7a-Hydroxycholesterol is a cholesterol oxide that has been described as biomarker of oxidative stress in subjects with impaired glucose tolerance and diabetes.
