Study Notes
Disaccharides
- Sucrose is formed by the condensation of glucose and fructose.
Polysaccharides
- Glycogen is the main energy storage molecule in animals.
- Amylopectin has a large number of side branches, allowing for quick energy release.
- Cellulose is composed of beta glucose molecules joined by beta 1,4 glycosidic bonds.
- Amylose is composed of alpha glucose molecules joined by alpha 1,4 glycosidic bonds.
Testing for Sugars
- Benedict's reagent is used to test for the presence of reducing sugars.
- Reducing sugars can be detected using a test for reducing sugars.
Plant Cell Structure and Function
- Cellulose provides structural support in plant cell walls and counteracts osmotic pressure.
- Starch is a storage polysaccharide in plants.
- Plant cells use glucose as an immediate energy source.
Additional Facts
- Glycogen is coiled and compact, storing a lot of energy in a small space.
- A condensation reaction between monosaccharides forms a glycosidic bond, forming polysaccharides.
- The main difference between amylose and amylopectin is that amylose is a straight chain, while amylopectin is branched.
- Cell walls are made up mostly of cellulose and provide structural support.
