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

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,
1957-58; Wald and Hubbard, 1957; Brown and Brown, 1958). Retinene, the
aldehyde of ...
