Definition of photopigment in English:

photopigment

nounˈfəʊtəʊˈpɪɡm(ə)ntˌfōdōˈpiɡmənt

A pigment whose chemical state depends on its degree of illumination, such as those in the retina of the eye.
Example sentencesExamples
- The green and red genes encode photopigments that respond to different, overlapping regions in the middle-to-long wavelength spectrum and are adjacent to each other on the X chromosome.
- The difference absorption spectroscopy in both living plasmodium and cell homogenate shows that there is a photopigment which converts reversibly between red and far-red types.
- It could involve retinal photoreceptors, extraretinal photoreceptors in the pineal or elsewhere, photopigments such as cryptochromes within the retina or brain, or it might be mediated through a non-visual pathway.
- Their physiological basis is reasonably well understood; they result from the saturation or bleaching of retinal photopigments under intense or prolonged illumination.
- There is no physiological evidence for a third photopigment sensitive to blue wavelengths.
