Erretinala edo erretinaldehidoa, konposatu organikoa da, aldehidoen familiakoa eta A bitaminaren hiru formetako bat. Zintzilik dagoen katean lau lotura bikoitz ditu eta ondorioz zis-trans isomeria du. Erretinaren zelula fotorrezeptoreetan aurkitzen da eta argiarekiko sentikorra dena[1][2].

Osorik trans isomeria duen erretinala

Erretinala opsina izeneko proteinei lotuta ageri da eta ikusmenaren prozesuan argia detektatzeko urratsean parte hatzen du.

Animalia ornodunek erretinala zuzenean haragitik lortzen dute edo karotenoideen degradaziotik.

Ikus, halaber
