- 1CelluloseThe major structural polymer of plants.
Formed from beta-glucose units with beta 1-4 links.
Alternate residues flip 180 resulting in inter-chain hydrogen bonding.
Cellulose molecules pack closely together to form strong fibers.
May be reinforced with lignin for strength. - 2StarchNutritional reservoir in plants.
Has two forms- amylose and amylopectin.
Both made entirely from glucose.
Amylose is unbranched with chain linked by a 1-4 glycosidic bond.
Amylopectin branch every 30 units. - 3GlycogenMost common homopolymer in animal cells.
Made entirely from glucose.
Nutritional reservoir.
Chain linked by alpha 1-4 glycosidic bonds.
Branches about every 10 units with an alpha 1-6 glycosidic bond. - 4MonosaccharideSimplest carbohydrate/hydrated carbon.
Smallest has three carbons.
Contains a carbonyl group.
Either an aldose or ketose depending on the position of the carbonyl. - 5DisaccharideTwo monosaccharides linked by a glycosidic bond.
Linkage is alpha or beta depending on the position of the hydroxyl on the anomeric carbon involved in the bond. - 6PolysaccharidePolymers of simple sugars connected by glycosidic bonds.
The most common building block is glucose. - 7ChitinIs a polymer of N-acetylglucosamine.
Derived from glucose.
Cell wall of fungi and exoskeleton of insects and crustaceans.
Beta 1-4 links.
Similar structure to cellulose.
