Visual cycle (WP5534)

Homo sapiens

The visual cycle, also known as the retinoid cycle metabolic pathway, regenerates vitamin A derived chromophore 11-cis retinal. This enables visual phototransduction response to light. Inspired by https://rgd.mcw.edu/rgdweb/pathway/pathwayRecord.html?acc_id=PW:0001005.
