3'-hydroxyechinenone	A member of the class of carotenone that is echinenone carrying an additional hydroxy substituent at position 3'. Found in cyanobacteria.	3'-hydroxyechinenone
adonixanthin	A carotenone that consists of beta,beta-caroten-4-one bearing two hydroxy substituents at positions 3 and 3' (the 3S,3'R diastereomer).	adonixanthin
astacin	A carotenone that consists of beta,beta-carotene bearing four oxo substituents at positions 2, 2', 4 and 4'.	astacene
astaxanthine	A carotenone that consists of beta,beta-carotene-4,4'-dione bearing two hydroxy substituents at positions 3 and 3' (the 3S,3'S diastereomer). A carotenoid pigment found mainly in animals (crustaceans, echinoderms) but also occurring in plants. It can occur free (as a red pigment), as an ester, or as a blue, brown or green chromoprotein.	astaxanthin
canthaxanthin	A carotenone that consists of beta,beta-carotene bearing two oxo substituents at positions 4 and 4'.	canthaxanthin
capsanthin		capsanthin
capsorubin		capsorubin
echinenone	A carotenone that is beta-carotene in which the 4 position has undergone formal oxidation to afford the corresponding ketone. Isolated as orange-red crystals, it is widely distributed in marine invertebrates.	echinenone
spheroidenone	The carotenone that is the 2-oxo derivative of (3E)-1-methoxy-3,4-didehydro-1,2,7',8'-tetrahydro-psi,psi-carotene.	spheroiden-2-one
