Toxic Properties of Holothurian’s Triterpene Glycosides

open access: yesJournal of NBC Protection Corps, 2019
Holothurians (or sea cucumbers) are echinoderms and are found in all areas of the world oceans. These animals produce special low-molecular metabolites - triterpene glycosides, which are a means of chemical protection of holothurians from predators.
