TL;DR: In decapod crustaceans the solubility of the surface active compounds, the formation of taurine or sulfate on hydrolysis, the precipitation of proteins in acid medium and the chromatographic behaviour are quite comparable to these properties in bile acids or bile alcohols.
Abstract: The digestive fluids of Holothuria tubulosa (Echinoderms), Aplysia limacine (Gastropoda), Aphrodite aculeala (Annelides) and of all the investigated decapod crustaceans (six species) have a low surface tension (between 75 and 50 % of that, of water).By means of the surface active substances they are able to dissolve small amounts of oleic acid and have a strong emulsifying influence on fats. The dissolving power in the crustaceans is about five times lower than that of vertebrates. In Holothuria and Aplysia it is still much lower than in the crustaceans. In the digestive juice of Cephalopoda surface active substances seem to be lacking.In decapod crustaceans the solubility of the surface active compounds, the formation of taurine or sulfate on hydrolysis, the precipitation of proteins in acid medium and the chromatographic behaviour are quite comparable to these properties in bile acids or bile alcohols. For the other systematic groups treated here, these points could not yet be elucidated. Becaus...
