Abstract
The act of seeing, i.e. vision, requires a chromophore capable of absorbing light. In a continuing series of studies Wald, Hubbard, and co-workers2 have shown that this visual pigment is formed from the combination of a protein with a particular polyene aldehyde. By far the greatest attention has been centered on the night vision pigment, rhodopsin. Its chromophore is derived from 11-cis retinal by reaction of the aldehyde group with a specific amino group on the protein3 (although there is some controversy over this point4). Further, the spectral properties of rhodopsin are best reconciled with the protonated (or acidified) form of this Schiff base.5
