To study the incorporation of 35S into lipid fraction in marine algae, Porphyra teneraand Ulva pertusa were culured for 48 hours in sea-water cotaining 35SO4--, and distribution of 35S in lipid fraction was examined. The results obtained are as follows;
1) In Ulva pertusa, 35S incorporatinon into lipid fraction was more active than in Porphyar tenera.
2) In both algae almost all of 35S were found in the acetone-insoluble fraction.
3) The acetone-insoluble fraction gave two 35S-containing compounds after deacylation. The one might be sulfoquinovose or its related compound originated from sulfolipid and the other was unkown.
4) It has been proved that sulfur uptake into the lipid fractions by these seaweeds showed a different patterns when compared with higher plants of photosynthetic microorganisms.
