A 1H and 13C n.m.r. study of all-trans retinal in dodecyldimethylamine oxide micelles

Complexes of all-trans retinal with dodecyldimethylamine oxide micelles at neutral pH have been characterized by proton and carbon-13 n.m.r. and u.v. spectroscopy. The chemical shift data show that the aldehyde group of all-trans retinal is directed towards the interfacial Stern layer with the polye...

Zusammenfassung:Complexes of all-trans retinal with dodecyldimethylamine oxide micelles at neutral pH have been characterized by proton and carbon-13 n.m.r. and u.v. spectroscopy. The chemical shift data show that the aldehyde group of all-trans retinal is directed towards the interfacial Stern layer with the polyene chain and the β-ionone ring solubilized by the hydrocarbon chains of the detergent. No self-association of all-trans retinal has been observed in these micelles.
