Abstract
LIGHT transforms visual purple, the substance responsible for scotopic vision, into a yellow compound, the colour of which depends on pH. (‘indicator yellow’1). Visual purple behaves as a coloured protein, that is, it is a ‘chromoprotein’. Experiments have been carried out to see if a shift of the iso-electric point occurs on bleaching.
