Biologically Active Triterpene Glycosides from Sea Cucumbers (holothuroidea, Echinodermata)
Sea cucumbers are characterized by their content in holothurins, triterpenoid glycosides that are responsible for the toxicity of these echinoderms. Nearly 100 holothurins isolated in the last twenty years are grouped into three main aglycone structural types: 3p-hydrox>iiolost-9(ll)-ene, 3p-hydrox5*iolost-7-ene and nonholostane based aglycones. This communication offers a general view of the s...

متن کاملBiomechanics of adhesion in sea cucumber cuvierian tubules (echinodermata, holothuroidea).
Several species of sea cucumbers, all belonging to a single family, possess a peculiar and specialized defense system, the Cuvierian tubules. It is mobilized when the animal is mechanically stimulated, resulting in the discharge of a few white filaments, the tubules. In seawater, the expelled tubules lengthen considerably and become sticky upon contact with any object. The adhesiveness of their...
