Lipid Structure 3 1 2 Fats, Oils, Waxes Energy for cells, cell structure, insulation Lipids & Proteins compose the cell membrane Cholesterol: gives cell membrane flexibility Stucture (2 parts): “Head” of glycerol “Tail” of fatty acids molecules Monomer: Fatty Acid Polymer: Lipid 3 1 2

Saturated Fats Long chain of C-C bonds (all single bonds) Each C is “saturated” with H atoms Solid at room temps Very common in animal fats

Unsaturated Fats Long chain of C-C bonds (some double bonds) Unsaturated: Less space for H atoms Liquid at room temps Plant fats
