The NADPH-dependent release of retinol is due to the action of a retinoldehydrogenase present in the rod sac membrane, which is capable of reduction of free retinaldehyde as well as of reductive hydrolysis of retinylidene aldimines (4, 5).作者: 虛情假意 時(shí)間: 2025-3-22 02:06

The kinetics of these slow reactions have recently been studied in the frog retina (1) where two parallel pathways for the decay of MII were demonstrated. Rate constants at 21.C were determined for these two reactions, for the decay of metarhodopsin III (MIII) and for the reduction of all-trans-retinal.作者: 古代 時(shí)間: 2025-3-24 18:35 作者: 察覺 時(shí)間: 2025-3-24 21:34
