摘要: Abstract Rates of hydrolysis a model retinylidene Schiff base chromophore, namely all-trans-N-retinylidene-β-naphthylamine (1), have been determined in tetrahydrofuran, CHCl3, and CH3CN, the presence absence metal cations (Li+, Mg2+) trichloroacetic acid as protonating agent. A mechanism for chromophore visual pigments representation role ions maintaining structure functions bacteriorhodopsin proposed.
