Lipids are major components of cellular membranes and energy stores. Lipids contribute vital structural, energetic, and signaling functions. We have optimized methods to extract and analyze lipids from the nematode Caenorhabditis elegans based on standard methods. Here we describe a method to extract total lipids from C. elegans larvae, adults, or embryos. We describe a thin-layer chromatography method to separate major lipid classes and a gas chromatography method to analyze fatty acid composition from lipid extracts, lipid fractions, or directly from nematode larvae, adults, or embryos.
Keywords: Fatty acid methyl esters; Gas chromatography; Lipid extraction; Neutral lipids; Phospholipids; Thin-layer chromatography.
