Opsin molecule F006 / 9665
Opsin. Molecular model of a ligand-free opsin molecule. Opsins are found in photoreceptor cells (rods and cones) in the retina of the eye. This opsin molecule forms a complex with retinal, called rhodopsin or visual purple, in rod cells. The retinal molecule absorbs light, which causes it to change shape and separate from the opsin. This initiates the transmission of nerve impulses to the brain, leading to the sensation of vision. The great sensitivity of rhodopsin is what allows vision in dim light

EDITORS COMMENTS
This print showcases the intricate structure of Opsin molecule F006 / 9665, a key component found in photoreceptor cells within the retina of our eyes. The ligand-free opsin molecule forms a crucial complex with retinal, known as rhodopsin or visual purple, particularly in rod cells. As light enters our eyes and reaches these specialized cells, the retinal molecule absorbs it, triggering a remarkable transformation that causes it to separate from the opsin. This separation sets off a chain reaction that ultimately leads to the transmission of nerve impulses to our brain, enabling us to experience the extraordinary sensation we know as vision. What makes rhodopsin truly exceptional is its incredible sensitivity to even dim light conditions, allowing us to see in low-light environments. The molecular model depicted in this artwork provides an insightful glimpse into the complex world of biology and genetics. With its alpha helix and beta sheet structures forming tertiary arrangements, this opsin molecule represents one piece of an intricate puzzle that contributes to our ability to perceive light and color. As we marvel at this stunning illustration against a pristine white background, let us appreciate how scientific research and medical advancements continue unraveling nature's mysteries. This image serves as a reminder of both the artistry inherent in biochemistry and healthcare professionals' tireless efforts towards understanding human vision better for improved medical interventions.
