Abstract A study is reported on the incorporation of14C-acetate into lipid classes from three different growth stages ofLaminaria japonica, a species long used for food in Japan. This was done because of the possible utilization of its lipids. Radioactivity incorporated into whole lipids in the three growth stages under the same experimental conditions (10 °C, 500 lux) increased with maturity of the thalli. The radioactivity was found mainly in PC, TG and 1,2-DG and subsequently distributed into other lipid classes (PG,PI,PE,MGDG,SQDG and DGDG) to a lesser extent. The incorporation patterns of the former group were similar at all stages, but those of the latter group differed slightly according to growth stage. In juvenile thalli,14C was incorporated to a much higher extent into PG, MGDG, PI and fucosterol than PE, SQDG, DGDG and MG, while the14C-incorporation into MG, SQDG, DGDG and PS in the mature growth stage was higher than into the other lipid classes. The absolute level of incorporation was higher for all these compounds in mature thalli than the thalli of other growth stages.
