Iodopsin vs. Photopsin

Iodopsinnoun

A photoreceptor protein found in the cone cells of the retina, the basis of colour vision.

Iodopsinnoun

a violet photopigment in the retinal cones of the eyes of most vertebrates; plays a role in daylight vision

Photopsinnoun

(protein) Any of a class of photoreceptor proteins present in the cones of the retina

Photopsin

Photopsins (also known as Cone opsins) are the photoreceptor proteins found in the cone cells of the retina that are the basis of color vision. Iodopsin, the cone pigment system in chicken retina, is a close analog of the visual purple rhodopsin that is used in night vision.
