Biological Macromolecules and Reactions

This video tutorial covers the formation and function of biological macromolecules, including carbohydrates, lipids, nucleic acids, and proteins. It explains how monomers combine to form polymers through dehydration reactions and how these polymers are broken down by hydration reactions. The video also discusses the roles of these macromolecules in cellular processes and provides examples of their functions in energy storage, information storage, and structural support. Additionally, it highlights the importance of enzymes in digestion and the breakdown of macromolecules.
