Photochemistry of Visual Purple
نویسنده
چکیده
It is shown that the velocity of bleaching of visual purple by light, under comparable conditions of concentration, volume, and surface exposed, is directly proportional to the intensity.

1. In the reception of light by the eye a common variable is the intensity of the illumination. Indeed, in order to analyse phenomena like dark adaptation and intensity discrimination it has been necessary to assume (Hecht, 1921-22, c; 1923-24, d) certain relations between the intensity of light and its action on the photosensitive material in the eye. The idea that visual purple is the sensiti...

The decay rate of the Bacteriorhodopsin (BR) photocycle intermediate M412 and proton, the proton pump efficiency (H+/M412), the ratios of M412 to other intermediates and the rotational correlation time (tauc) in purple membrane (PM) fragments treated by the zwitterionic detergent 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS) with different concentrations were studied. The r...
