noun | / LIK-wid PUR-pul /

1. (biochemistry) Also known as visual purple or rhodopsin — a light-sensitive receptor protein found in the rods of the retina. It enables vision in dim light by transforming invisible darkness into visible form. Derived from the Greek rhódon (rose) and ópsis (sight), its name reflects its delicate pink hue and vital role in perception.
