Key to Xenobiotic CarotenoidsDOI: 10.3390/molecules17032877 Keywords: carotenoids, xanthophylls, fluorocarotenoids, chlorocarotenoids, bromocarotenoids, iodocarotenoids, silicon carotenoids, nitrogen carotenoids, sulfur carotenoids, selenium carotenoids, iron carotenoids Abstract: A listing of carotenoids with heteroatoms (X = F, Cl, Br, I, Si, N, S, Se, Fe) directly attached to the carotenoid carbon skeleton has been compiled. The 178 listed carotenoids with C,H,X atoms demonstrate that the classical division of carotenoids into hydrocarbon carotenoids (C,H) and xanthophylls (C,H,O) has become obsolete.
