| Abstract |
The composition of metabolites in the coelomic fluid of the starfish Asterina pectinifera and sea urchin Mesocentrotus nudus was studied under normal and hypoxic conditions using NMR spectroscopy. Their change after keeping animals under hypoxia was shown. Sea urchins revealed the presence of anaerobic metabolism, which intensifies under stress in conditions of hypoxia. No similar mechanism of energy metabolism has been found for the starfish. Under conditions of hypoxia, a significant increase in lactate, which is observed in sea urchins, is not observed in the composition of the coelomic liquid of starfish. Asterine tissues contain a mixture of carotenoids in large quantities, the most well-known of which is astaxanthin. The starfish Asterina pectinifera can be used as a raw material for new medicinal, cosmetic, and food products. |
