Common NameDemethylspheroidene
DescriptionDemethylspheroidene belongs to the class of organic compounds known as xanthophylls. These are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Thus, demethylspheroidene is considered to be an isoprenoid lipid molecule. Demethylspheroidene is found in Myxococcus xanthus, Rhodobacter capsulatus and Rhodobacter sphaeroides. Demethylspheroidene was first documented in 1980 (PMID: 7358679). Demethylspheroidene is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 16086104) (PMID: 16158287) (PMID: 16228308).
