Morphology

dehydroretinol = retinol (opaque) = dehydro + retinol

The formation is a chemical derivation ('dehydro-' + 'retinol') that requires specialist chemical knowledge; general learners cannot reliably infer the meaning.

Etymology

Dehydroretinol breaks into de- 'remove', hydro- 'hydrogen', and retinol, the vitamin A 'alcohol' named after the retina (the eye). So dehydroretinol is a form of vitamin A with less hydrogen than plain retinol, which helps explain why it is often less active in mammals and is common in some fish.
