Previous Indexing: BETA CAROTENE/*aa (1997-2006); CAROTENE/*analogs & derivatives (77-96); *CAROTENOIDS (69-76); CYCLOHEXANOLS (74-75); ETHERS, CYCLIC (74-76)
Heading Mapped to: Xanthophylls
Frequency: 261
Note: a carotene epoxide that is precursor to capsanthin; one of 3 xanthophylls involved in evolution of plastids of green plants (oxygen evolution); 3 (violaxanthin, zeaxanthin & antheraxanthin) participate in series of photo-induced interconversions known as ''violaxanthin cycle''; structure; cleavage of 9-cis-epoxycarotenoids (violaxanthin) to xanthoxin, catalyzed by 9-cis-epoxycarotenoid dioxygenase, is the key regulatory step of ABSCISIC ACID biosynthesis
