The distribution of sulfolipid in marine mollusks

1. All marine mollusks examined contained low concentration (1-3% of total lipid) of sulfolipid.2. Sulfolipid contents of the gonads and the digestive diverticula were higher than those of the other tissues.3. The difference in the level of sulfolipid in the gonads was observed between the male and female.4. Sulfolipid content of the gonads of Cellana grata grata showed seasonal fluctuation.5. 35S-sodium sulfate injection experiment showed that the scallop has a limited ability to synthe-size sulfolipids.
