Organic Molecules and Polymers Concepts

The video introduces organic molecules, focusing on carbon's unique properties and its role in forming complex molecules. It explains the concepts of monomers and polymers, using proteins and sugars as examples. The video also covers different types of bonds and their impact on molecular stability. A detailed discussion on carbohydrates follows, highlighting their structure, types, and biological significance, including polysaccharides like starch, glycogen, and cellulose.
