Visual Cycle:
- In this cycle, initially on exposure to lip, high isomerization of 11 cis-retinal lo all Irans-regional occurs
- All Irans-retinal is immediately isomerized lo 11-cis-retinal
- This combines with opsin & forms Rhodopsin
- Most of all Irans-retinal is transported to liver
- It is converted to all Irans-retinol by alcohol dehydrogenase
- All trans-retinol is isomerized lo 1 l-cis-retinol
- This is oxidized lo 11-cis-retinal by alcohol dehydrogenase
- Now this re-enters into the visual cycle
