Canthaxanthin (β, β-carotene 4, 4′ dione) is used widely as a drug or as a food and cosmetic colorant, but it may have some undesirable effects on human health, mainly caused by the formation of crystals in the macula lutea membranes of the retina. This condition is called canthaxanthin retinopathy. It has been shown that this type of dysfunction of the eye is strongly connected with damage to the blood vessels around the place of crystal deposition. This paper is a review of the experimental data supporting the hypothesis that the interactions of canthaxanthin with the lipid membranes and the aggregation of this pigment may be the factors enhancing canthaxanthin toxicity towards the macula vascular system. All the results of the experiments that have been done on model systems such as monolayers of pure canthaxanthin and mixtures of canthaxanthin and lipids, oriented bilayers or liposomes indicate a very strong effect of canthaxanthin on the physical properties of lipid membranes, which may explain its toxic action, which leads to the further development of canthaxanthin retinopathy.

The contents of astaxanthin, canthaxanthin and astaxanthin esters were studied in natural populations of the copepod Acartia bifilosa from the Pomeranian Bay and Gulf of Gdańsk in the southern Baltic Sea. Samples dominated by any one of three developmental groups: (1) nauplii, (2) copepodids I–III and (3) copepodids IV–V and adults of Acartia bifilosa were analysed by means of high performance liquid chromatography (HPLC). As ontogenetic development progressed, significant changes occurred in the proportion of particular pigments in the total pigment pool of the various developmental groups. Astaxanthin and canthaxanthin occurred in all the groups, the former being clearly dominant. However, an increasing percentage of astaxanthin esters was recorded in the copepodids I–III, and even more in the copepodids IV–V and adults group. Most probably, astaxanthin is the main pigment active in copepod lipid metabolism. Carotenoid pigments in copepods very likely act as efficient free-electron quenchers and may be involved as antioxidants in rapid lipid metabolism. The exogenously feeding stages (late nauplii and copepodids) transform plant carotenoids taken from food and are evidently capable of metabolising astaxanthin by esterification and further degradation. It is emphasised that, according to literature data, astaxanthin esters may have an even higher quenching ability. It is suggested that crustacean carotenoid pigments, with their electron donor-acceptor abilities, may replace oxygen in peroxidation processes connected with lipid metabolism. The consequences of such a physiological role of astaxanthin for present-day estimations of energy balances in zooplankton communities are mentioned.
