general monomers of lipids (dietary fat) - glycerol & fatty acids, Saturated Fats - no double bonds, filled with hydrogens, Unsaturated Fats - liquid at room temp., double bonds, not filled with hydrogens, considered "good fats" partly because plant products come with other great properties!, FUNCTIONS OF FATS - insulation, cushioning, important part of cell membrane, long term energy storage, hormones, myelin of nerve cell, etc., PHOSPOLIPIDS, EICOSANOIDS, STEROIDS - amphiphilic- one end polar, other non-polar- CELL MEMBRANE, LIPID-BILAYER of cells, Hydrophobic - Water fearing portion of CM- non-polar tails, Hydrophilic - Water loving portion of CM- polar-heads, hydrogenated oils - oils that have been chemically modified in the lab to increase shelf life by forcing hydrogens to saturate- THESE are the BAD ones!!!!, Eicosanoids/Prostaglandins - "hormone-like" chemicals (travel short distances); important in cell signaling, inflammation, blood clotting, etc., TRIGYLCERIDES - saturated/unsaturated fats found in our diet, Steroids - cholesterol synthesized hormones (testosterone, estrogen, bile acids, also important part of cell membrane) , Neutral  - nonpolar lipids such as waxes and triglycerides,
