Glycogen, Chitin, and Polysaccharides

This video tutorial covers the basics of polysaccharides, including their structure and function. It begins with an overview of monosaccharides and disaccharides, then delves into polysaccharides like starch, glycogen, cellulose, and chitin. Starch is explained with its two types, amylose and amylopectin, highlighting their glycosidic bonds. Glycogen, found in animals, is compared to plant starch. Cellulose's structural role in plants is discussed, along with its beta bonds. Finally, chitin's structural function in insects is introduced.
