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.

The sterol ring system is common to all sterols; the differences are in the side chain. They are 28- or 29-carbon alcohols. 7 Î²-sitosterol is the most common plant sterol and is structurally similar to cholesterol. 1 Because of this structural similarity, Î²-sitosterol can replace cholesterol in the human body. 2 Î²-sitosterol is a 4-desmethyl sterol (containing no methyl groups at carbon atom number 4).
