“…In contrast, early work by Wald indicated that photolysis of dilute ethanolic solutions of all-trans -retinal resulted in the formation of about 50% cis -retinals, with an exceptionally high contribution of 11- cis -retinal representing 25% of the mixture. Since then, quantum yields for trans/cis and cis/trans photoisomerization upon light excitation of retinal have been studied under a variety of conditions demonstrating both isomer and solvent dependence. The quantum yields for all-trans -retinal were considerably lower in polar (0.1–0.2) than in nonpolar (0.4–0.7) solvents. …”

“…In the early stage(s) of the photobleaching of rhodopsin, its chromophore 11-cis retinal, bound to the €-amino group of a lysine residue of the protein opsin via a protonated Schiff base linkage, is photoisomerized to its all-trans form (references 3-13 in Waddell et al, 1977). These findings, coupled with the facts that the low-energy absorption of the pigment and the mechanism of the visual process are still far from well understood, have produced a considerable amount of research on the spectroscopy and photochemistry of analogous model systems including retinals, retinols and retinyl Schiff bases (for reviews, see Honig and Ebrey, 1974;Land, 1975;. In particular, the Schiff bases (SB) of retinals with simple amines (e.g.…”

“…Initially we tested this putative interaction between retinoids and carotenoids in an in vitro system. In a test tube, quantum yields for trans/cis and cis/trans photoisomerization of RAL are considerably lower in polar (0.1-0.2) than in nonpolar (0.4-0.7) solvents (30). Therefore, we prepared 10 mM RAL in a nonpolar solvent (hexanes) in a quartz glass cuvette and added increasing amounts of zeaxanthin (0-100 mM).…”
