Carbohydrates

Mr. Anderson discusses carbohydrates, their types, and roles in energy and structure. He explains monosaccharides like glucose, fructose, and galactose, and disaccharides like sucrose and lactose, including lactose intolerance. The video covers oligosaccharides and polysaccharides, their biological importance, and processes like hydrolysis and dehydration. It concludes with the impact of sugar on health.
