The chemistry of vision : Rhodopsin, photopsin – ദ കെമിസ്ട്രി ഓഫ് വിഷൻ : റോഡോപ്സിൻ, ഫോട്ടോപ്സിൻ

Rhodopsin is a light-sensitive pigment that is found in the rods of the retina. It is composed of an organic molecule called retinal that is covalently bonded to the protein opsin. Rhodopsin is activated when light of a specific wavelength hits it, causing a conformational change in the molecule which triggers a photochemical reaction. This …

Retina and the photoreceptors – റെറ്റിനയും ഫോട്ടോറിസെപ്റ്ററുകളും

The retina is a light-sensitive tissue located at the back of the eye. It is composed of two types of photoreceptor cells, rods and cones, which convert light into electrical signals that are sent to the brain. Photoreceptors are specialized cells found in the eyes that are responsible for converting light into electrical signals that …
