Nucleic acid Nucleotide Polynucleotide or nucleic acid Information storage and transfer Contain N in rings, nucleotides made of sugar, phosphate and nitrogenous base
Lipid * Glycerol, fatty acids Fats, oils, waxes, phosopholipids, steroids Membrane structure, energy storage, insulation Made of C,H, and O; lots of C-H bonds; may have some C=C bonds (unsaturated); steroids have 4 rings
