چکیده انگلیسی
The synthesis of 11-fluoro-all-trans-retinol (11-F-tROL), which is shown to be an excellent substrate for processing by visual cycle enzymes, is described. It is isomerized to its 11-cis congener subsequent to its esterification by lecithin retinol acyl transferase (LRAT) approximately as well as is vitamin A itself. The enzymatic turnover of 11-F-tROL is unaccompanied by enzyme inhibition. The previously reported lack of isomerization of this substrate had been suggested as evidence for a carbonium mechanism in the critical enzymatic isomerization pathway in vision. The mechanism of this process remains unknown.
