Biological Molecules and Carbohydrates

This video introduces biological molecules, focusing on monomers, polymers, and monosaccharides. It explains the definitions and examples of monomers and polymers, and classifies carbohydrates into monosaccharides, disaccharides, and polysaccharides. The video provides a detailed look at glucose, its structure, and its isomers, alpha and beta glucose. It concludes with a summary of key points and guidance for the next lessons.
