Macromolecules and Their Reactions

The video introduces macromolecules, explaining that they are made of monomers. It covers the formation of polymers through covalent bonds, using glucose as an example. The video details the four types of macromolecules: carbohydrates, lipids, nucleic acids, and proteins, and their respective monomers. It explains dehydration synthesis and hydrolysis reactions, highlighting their roles in forming and breaking down macromolecules.
