Common Name | 7alpha-Hydroxycholesterol |
---|
Description | 7alpha-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 a biomarker of oxidative stress in subjects with impaired glucose tolerance and diabetes (PMID: 16634125 ). 7alpha-Hydroxycholesterol has been identified in the human placenta (PMID: 32033212 ). |
