While wild type
whole worm lipid extracts contain a TAG/PL ratio of 1.2 (±0.2), lipid
droplets contain a TAG/PL ratio of 21.3 (±2.8). The daf-2 mutants
showed an even higher enrichment of TAG stores, with the whole
worm TAG/PL ratio of 1.8 (±0.2) and a TAG/PL ratio in isolated daf-2
lipid droplets of 38.0 (±2.7) (Fig. 1B). Both wild type and daf-2 lipid
droplets have higher PC to PE ratio than whole worm extracts, with a
PC/PE ratio of 3.8 (±0.6) in wild type lipid droplets compared to a 1.3
(±0.1) ratio in whole worm extracts (Fig. 1C).
