Chemical Information
FooDB Name7a-Hydroxycholesterol
Description7alpha-hydroxycholesterol is an oxysterol and can serve as a biomarker for lipid peroxidation. (PMID: 17386651) Products of cholesterol oxidation accumulate within atherosclerotic plaque and have been proposed to contribute to inflammatory signalling in the diseased artery. (PMID: 17364953) 7alpha-hydroxycholesterol is a cholesterol oxide that has been described as biomarker of oxidative stress in subjects with impaired glucose tolerance and diabetes.
