Macromolecules and Their Functions

The video introduces macromolecules, essential large molecules in our bodies, and their roles. It covers the structure and function of macromolecules, emphasizing carbon's role and various functional groups. The processes of dehydration synthesis and hydrolysis are explained, along with the types of macromolecules: carbohydrates, lipids, proteins, and nucleic acids. The video also provides guidance on identifying macromolecules based on their structure.
