Resumen

The four major sulfolipids in the non-photosynthetic marine diatom, Nitzschia alba, were isolated in pure form and their structures were established spectrometrically and by identification of their hydrolysis products as (a) 24-methylene cholesterol sulfate, (b) 1-deoxyceramide-1-sulfonate, (c) phosphatidyl sulfocholine (a sulfonium analogue of phosphatidylcholine) and (d) sulfoquinovosyi diglyceride. The major characteristic fatty acids of the sulfolipids were: for the deoxyceramide sulfonate, 16:0 (26%) and 16:1-Δ³-trans (64%); for the sulfonium analogue, 14:0 (30%), 18:1 (12%), 18:2 (8%), 20:5 (27%) and 22:6 (4%); and for the sulfoquinovosyl diglyceride (two species, respectively), 14:0 (9%, 22%), 16:0 (16%, 28%), 18:1 (8%, 22%), 20:5 (42%, 23%) and 22:6 (14%, 2%). Traces of lyso-derivatives of sulfoquinovosyl diglyceride and phosphatidyl sulfocholine were also detected. The deoxyceramide sulfonate and the phosphatidyl sulfocholine represent novel membrane lipid components not previously detected in other organisms. They may however have a widespread distribution in marine diatoms and perhaps in marine organisms generally.
