A new class of lipids: chlorosulfolipids.

Acid hydrolysis of sulfolipids from Ochromonas danica liberates 13-chloro-docosan-1,14-diol; 11,15-dichloro-docosan-1,14-diol; and other docosan-diols with three to six chlorine atoms per molecule. In stationary cells grown on 1.47 mM Cl(-), the majority of sulfolipids are chlorinated, with the hexachloro species being the most abundant.
