Lecture 18: Chapters 9 and Polysaccharides and Overview of Carbohydrate Metabolism
Lecture18 Outline: Text Book: Chapter 9 and Chapter 23 • Structural Polysaccharides • Storage Polysaccharides • Overview of Glycogen Metabolism • Glycogen Synthesis (Glycogenesis) and it’s Hormonal Regulation
Polysaccharides Natural carbohydrates are usually found as polymers These polysaccharides can be • homopolysaccharides • heteropolysaccharides • linear • branched Polysaccharides do not have a defined molecular weight: contrast to proteins because unlike proteins, no template is used to make polysaccharides Functionally, Polysaccharides can serve as: o Structural materials, providing support to cells o Storage of energy sources
