Sulphonium analogue of lecithin in diatoms

Sulphonium analogue of lecithin in diatoms

PHOSPHATIDYL choline (lecithin) is the most widespread of the phospholipid membrane components of eukaryotic cells, being present in virtually all those investigated so far. The exceptions noted until recently have been blue-green algae 1 , the yeast-like fungus Pullularia pullulans 2 and the phytof...

Zusammenfassung:PHOSPHATIDYL choline (lecithin) is the most widespread of the phospholipid membrane components of eukaryotic cells, being present in virtually all those investigated so far. The exceptions noted until recently have been blue-green algae 1 , the yeast-like fungus Pullularia pullulans 2 and the phytoflagellate, Ochromonas danica 2 . We report here a sulphonium analogue of phosphatidyl choline which completely replaces lecithin in the non-photo-synthetic diatom, Nitzschia alba 4 . The new phospholipid is a phosphatidyl S,S-dimethyl mercaptoethanol (phosphatidyl sulphocholine) with the following structure:
