Sterols are a subgroup of steroids with a hydroxyl group at the 3-position of the A-ring. They are amphipathic lipids synthesized from acetyl-coenzyme A via the HMG-CoA reductase pathway. The overall molecule is quite flat.terols are a subgroup of steroids with a hydroxyl group at the 3-position of the A-ring.

Steroid ring system: The parent ABCD steroid ring system (hydrocarbon framework) is shown with IUPAC-approved ring lettering and atom numbering. A steroid is an organic compound with four rings arranged in a specific configuration.Examples include the dietary lipid cholesterol, the sex hormones estradiol and testosterone and the anti-inflammatory drug dexamethasone.teroids vary by the functional groups attached to this four-ring core and by the oxidation state of the rings. Sterols are forms of steroids with a hydroxyl group at position three and a skeleton derived from cholestane.
