GCE CIE BIOL - Molecular Structure of Polysaccharides
Chapter 2 Biological Molecules
2.2.e Describe the molecular structure of polysaccharides including starch (amylose and amylopectin), glycogen and cellulose and relate these structures to their functions in living organisms.
The table above shows the similarities and differences between amylose and amylopectin
✍️Note: ‘1,4 linked’ means there is a link between carbon atoms 1 and 4 of successive glucose units.
The above image shows the branched and helical structures of amylopectin and amylose.
⚡💯If a GCE CIE Biology exam question on the similarities between amylose and amylopectin arises, make sure to use the following key terms to get full marks:
The above image shows the branched structure of glycogen.
The above image shows the structure of cellulose.
Alrighty! Completed! 😋
