    Notes: [Auszug] This study concerns charge delocalization in protonated retinals. I have recently analysed NMR spectra of the stable isomers of retinal in C2HC13 solution3, and studied the effect of acid on the methyl and proton resonances of the polyene chain on protonation. The effect of protonation of ...

    Notes: [Auszug] A complete analysis of the proton NMR spectra of the six stable steroisomers of retinals has been undertaken. 11-cis-Retinal, the prosthetic group of the visual pigment rhodopsin, relieves steric strain between 10 H and 13 CH3 groups by a skew geometry around diene unit ...

    Notes: [Auszug] The specific recognition by enzymes of one of the C4 protons of the dihydronicotinamide ring (4HN) in NADH suggests a stereochemical nonequivalence for these hydrogens, which could arise from (a) a slow boat-boat inter-conversion of the dihydronicotinamide ring giving axial and equatorial 4 ...
