Bacteriorhodopsin. Diagram of the molecular structure of bacteriorhodopsin, a protein found in primitive micro-organisms known as Archaea. At centre is cis-retinal (red, a form of vitamin A), surrounded by alpha helices (spirals) and polypeptide loops (loops at top and bottom). On either side are the membranes (yellow) of the cells in which the protein is present.
