A plant-derived sterol or steroid compound, sometimes used in pharmaceutical or nutritional contexts.
From 'chorto-' (possibly from Greek 'chortos' meaning grass or plant) + '-sterol' (from Greek 'stereos' meaning solid, referring to steroid compounds). This appears to be a specialized pharmaceutical or biochemical term.
Plant sterols like those in 'chortosterol' have become popular in functional foods because they can actually lower cholesterol when consumed regularly—some margarines and yogurts now include them, representing a clever way modern nutrition science is hijacking plant chemistry to improve health.
