Abstract
Carotenoids in cyanobacteria have two main functions: they serve as light-harvesting pigments in photosynthesis, and they protect against photooxidative damage. Carotenoids are generally hydrophobic isoprenoid compounds that are synthesized in membranes. They mostly accumulate in protein complexes in the photosynthetic membrane, in the cell membrane and in the cell wall. In addition to the prevailing $-carotene and zeaxanthin, cyanobacteria contain unique ketocarotenoids such as echinenone and canthaxanthin. They do not synthesize $-rings and therefore contain $-, but not $- or $-, carotenes and their oxygenated forms. Glycosylated carotenoids are also very common in cyanobacteria.
