The polymers are the long chains of the repeated subunits.
All the four macromolecules given above carbohydrates, nucleic acid, lipids and proteins are polymers.
The carbohydrates are the polymer of sugars (monosaccharide).
The nucleic acid are the polymers of the nucleic acid (Deoxyribonucleic acid -DNA and ribonucleic acid- RNA).
The lipids are the polymer of glycerol and fatty acids.
The proteins are the polymers of the amino acids.
