%0 Journal Article %T Key to Xenobiotic Carotenoids %A Hans-Richard Sliwka %A Vassilia Partali %J Molecules %D 2012 %I MDPI AG %R 10.3390/molecules17032877 %X 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. %K carotenoids %K xanthophylls %K fluorocarotenoids %K chlorocarotenoids %K bromocarotenoids %K iodocarotenoids %K silicon carotenoids %K nitrogen carotenoids %K sulfur carotenoids %K selenium carotenoids %K iron carotenoids %U http://www.mdpi.com/1420-3049/17/3/2877
