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.

缺氧胁迫条件下黑海胆 Mesocentrotus nudus (Echinoidea) 和海星 Asterina pectinifera (Asteroidea) 体液代谢物组成的变化

摘要

使用核磁共振波谱在正常和缺氧条件下研究了海星Asterina pectinifera和海胆Mesocentrotus nudus体腔液中代谢物的组成。显示了将动物置于缺氧状态后的变化。海胆揭示了厌氧代谢的存在，这种代谢在缺氧条件下的压力下会加剧。海星没有发现类似的能量代谢机制。在缺氧条件下，在海胆中观察到的乳酸显着增加，在海星体腔液的组成中没有观察到。Asterine组织含有大量的类胡萝卜素混合物，其中最著名的是虾青素。海星Asterina pectinifera可用作新药、化妆品和食品的原料。
