Figure 1. Structures of cholesterol and major oxysterols. Oxysterols are cholesterol oxide products resulting from the autoxidation or enzymatic oxidation of cholesterol. The major oxysterols resulting from autoxidation (7-ketocholesterol; 7α-hydroxycholesterol, and its enantiomer 7β-hydroxycholesterol) and enzymatic oxidation (cholesterol-5α, 6α-epoxide, and its enantiomer cholesterol-5β,6β-epoxide) of cholesterol are represented.
