ISOMERS OF 3,7,11‐TRIMETHYLDODECA‐2,4,6,8,10‐ PENTAENAL (A LINEAR ANALOGUE OF RETINAL) and LOWER HOMOLOGUES IN THEIR INTERACTION WITH BOVINE OPSIN and BACTERIOOPSIN

Abstract
Abstract— The all‐trans and 3 mono‐cir isomers of the title linear pentaenal have been prepared. Results of their interaction with bovine opsin and bacterioopsin are presented. Likewise, the negative results on two lower member homologs are described. Implications on the specificity of the binding sites are discussed.
