Adaptative role of carotenoids and carotenoproteins in Cyclops kolensis Lilljeborg (Crustacea: Copepoda) specimens to extremely eutrophical conditions
Languages of publication
The authors, using column, thin-layer, and ion-exchange chromatography, investigated carotenoid and carotenoprotein complex content in Cyclops kolensis specimens from an extremely eutrophic pond. The following carotenoids were found to be present: b-carotene, b-cryptoxanthin, lutein epoxide, crustaxanthin, 4?-hydroxyechinenone, canthaxanthin, and astaxanthin. Carotenoprotein complex containing astaxanthin as the prosthetic group name g-crustacyanine was purified from Cyclops kolensis individuals examined. The authors justify the adaptative role of these pigments in Cyclops kolensis specimens in extremely eutrophical conditions.
