Interacting selectively and non-covalently with 11-cis retinal, an isomer of retinal that plays an important role in the visual process in most vertebrates. 11-cis retinal combines with opsin in the rods (scotopsin) to form rhodopsin or visual purple. Retinal is one of the three compounds that makes up vitamin A. Interacting selectively and non-covalently with all-trans retinal, a compound that plays an important role in the visual process in most vertebrates. All-trans retinal (trans r., visual yellow) results from the bleaching of rhodopsin by light, in which the 11-cis form is converted to the all-trans form. Retinal is one of the forms of vitamin A. The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. Interacting selectively and non-covalently with retinoids, any member of a class of isoprenoids that contain or are derived from four prenyl groups linked head-to-tail. Retinoids include retinol and retinal and structurally similar natural derivatives or synthetic compounds, but need not have vitamin A activity. Interacting selectively and non-covalently with retinal, one of the forms of vitamin A. Retinal plays an important role in the visual process in most vertebrates, combining with opsins to form visual pigments in the retina. Interacting selectively and non-covalently with a vitamin, one of a number of unrelated organic substances that occur in many foods in small amounts and that are necessary in trace amounts for the normal metabolic functioning of the body. Interacting selectively and non-covalently with any isoprenoid compound, isoprene (2-methylbuta-1,3-diene) or compounds containing or derived from linked isoprene (3-methyl-2-butenylene) residues.
