This study investigates how bacterial diets and stressors impact lipid metabolism in Caenorhabditis elegans (C. elegans). Nematodes were fed different bacterial diets and exposed to either glucose stress or food deprivation. Lipids from these animals were extracted and analyzed by HPLC and mass spectrometry. Preliminary observations for experiments analyzing dietary restriction using paraformaldehyde and oxidative stress using tert-butyl hydroperoxide were compared with the prior stress experiments. Bacterial diets influence phospholipid distribution, while stressors induce changes, from subtle to significant, in lipid composition, suggesting adaptive metabolic responses. These findings help explain the complex intersection between diet, stress, and lipid metabolism in C. elegans, warranting further investigation into various stressors.
