Acetylenic Compounds of Marine Origin

4 Acetylenic Compounds of Marine Origin.- A number of acetylenic compounds have been isolated from a variety of marine organisms, including molluscs,sponges and seaweeds. The nudibranch mollusc 

Diaulula sandiegensis contains nine chlorinated acetylenes, 

The Mediterranean nudibranch Peltodoria atromaaulata and its prey, the sponge Petrosia fiaiformis, contain a number of common metabolites and these have now been shown to include a number of 

fiaifovmis is normally red-brown due to the presence of a symbiotic alga. Sponges of this species living in dark caves lack the alga and are white. In a further study these white sponges 

The red marine alga Liagora favinosa contains three acetylenic lipids (61) - (63) °.
