Video: Vitamin A and Vision

10/01 

Video highlight: <I>Generation of rhodopsin</I>Video highlight: Generation of rhodopsin

Carrots contain beta-carotene. Our bodies convert it into a form of Vitamin A called retinal. Retinal is important for the first chemical step in human vision, called phototransduction.

This process starts in the retina which contains two types of photoreceptor cells: the rods and the cones. Although this video exemplifies how Vitamin A works in the rods, the molecular machinery in both types of cells is similar. Learn how Vitamin A activates the molecular pathways that are essential for vision.

Visit PDB-101 to watch Vitamin A and Vision.
