Retinene1 is better known as retinaldehyde or simply '''retinal''' and is fundamental in the transduction of light into visual signals in the Photoreceptor level of the Retina . Retinene2 is more formally known as '''dehydroretinaldehyde'''. The energy of impinging Photon s will convert retinaldehyde from an 11-cis Isomer into an all-trans form. In the retina, this conversion induces a conformational change in the surrounding Photopsin Protein pigment, leading to signaling through the G Protein Transducin . Retinaldehyde also forms a part of Bacteriorhodopsin , a light-induced Proton Pump found in some Archaea . Experimentally, it is possible to replace 11-cis retinaldehyde by perfusing retinal tissue preparations with retinaldehyde derivatives. Selective modification of the retinaldehyde structure, particularly the density of electrons in the π-orbital s, can lead to insights into the interaction between the retinaldehyde moiety and the surrounding pigment protein. |
