For each of the four major biomolecules, identify the name and structures of its monomer

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.
