In this video we cover the uses of polysaccharides as energy stores and structural units. On the way we’ll look the use of glucose in respiration, and then how it can be stored in the form of starch and glycogen, revisiting glycosidic bonding and introducing amylose and amylopectin. Then we will cover the bonding in cellulose making microfibrils, then macrofibrils and pectins, all the while linking structure to function. As ever there’s an exam style question to solidify everything learnt.
