retinol dehydrogenase

ret·i·nol de·hy·dro·gen·ase

an oxidoreductase catalyzing interconversion of retinal and NADH to retinol and NAD+.

ADH7

A gene on chromosome 4q23-q24 that encodes class-IV alcohol dehydrogenase 7 mu or sigma subunit, which like other alcohol dehydrogenases metabolises various substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids and lipid peroxidation products. ADH7 is inefficient in ethanol oxidation; it is the most active as a retinol dehydrogenase and may participate in synthesising retinoic acid—which is required for cellular differentiation. ADH7 is highly expressed in the stomach.

Once inside the target cell, retinol is converted into retinaldehyde by a retinol dehydrogenase (ROLDH), which in turn is converted to ATRA by retinaldehyde dehydrogenase (RALDH).
