Biochem Physiol Actions: A carotene epoxide that is precursor to capsanthin; one of 3 xanthophylls involved in evolution of plastids of green plants (oxygen evolution) and participating in photo-induced interconversions known as violaxanthin cycle. The cleavage of 9-cis-epoxycarotenoids (violaxanthin) to xanthoxin is the key regulatory step of abscisic acid biosynthesis.
