Photosensitive Substances of the Retinal Receptors : The photosensitive
substances of the rods and cones are made up of a protein called opsin and
retinene, the aldehyde of vitamin A. The human retinene is known as retinene-al
to ...

possibility that retinene combines with amino groups in opsin has been
considered (71, 72), but apparently retinene combines more easily with sulfhydryl
gr0ups than with amino groups at pH 6 which is optimal for rhodopsin formation (
73, 74).
When this substance absorbs a sufficient amount of light energy, it splits into its
constituent parts, opsin and trans- retinene. This reaction alters the generator
potential of the rod, which, in turn, produces activity of the associated neuron.

rhodopsin bleaches when exposed to light, and a lipid, the protein opsin, and

One may assume that the interference or block caused by night blindness would
lie at the place indicated by the vertical arrows and would, in fact, make a
conversion of vitamin A into retinene impossible or difficult. That lack of vitamin A
can ...

There are photosensitive or visual pigments in the rods and cones and these
consist of the aldehyde form of vitamin A, called retinene, combined with protein
molecules, to give two pigments absorbing light at different wavelengths.
Frederick Stratten Russell, Charles Maurice Yonge, 1969
The visual pigments of all animals that have been examined are formed of
protein (opsin) conjugated to retinene (Wald, 1958; Hubbard and St. George,

aldehyde of ...
