What is glycogen?
|
Animals store excess sugar in the form of another glucose polysaccharide. More highly branded than starch.

|
What is chitin?
|
- structural polysaccharide
- used by insects and crustaceans to build their exoskeleton, the hard case enclosing the animal. - cell walls of fungi |
|
|
Compare and Contrast starch and cellulose, two plant polysaccharides.
|
Both are polymers of glucose, but the bonds between glucose monomers have diff. shape. Starch functions mainly for sugar storage. Cellulose is a structural polysaccharide that is the main material of cell walls.

Diverse compounds that are grouped together because they share one trait: They mix poorly, if at all, with water. Thus hydrophobic.
|
