There are four main groups of macromolecules:
1. Nucleic acids (DNA and RNA)-monomers are nucleotides; provide genetic information
2. Proteins-monomers are amino-acids; structural, catalytic, regulatory roles
3. Lipids (fats)-monomer units are free fatty acids; structural, energy, insulation roles
4. Carbohydrates (sugars)-monomer units are monosaccharides (like glucose); energy source, structural function.
