Carbohydrates 2 : Polysaccharides As Energy Stores Flashcards
Define homopolysaccharide
They are made up of one kind of monosaccharide
Define heteropolysaccharide
They are made up of more than one monosaccharide
Where do plants store energy
As starch in chloroplasts and in membrane bound starch grains
Where do humans store energy
As glycogen in cells of the muscles and liver
Why does the hydroxyl group on carbon 2 have to stay on the inside of the amylose spiral
To help maintain the structure of the coil and making it less soluble
What kind of bonding holds the coiled structure of amylose
Hydrogen bond
An advantage of glycogen and starch
They are compact, meaning they do not occupy a lot of space. They occur in dense granules of the cell.
An advantage of polysaccharides
They hold glucose molecules in chains, so they can be easily snipped off by hydrolysis when required for respiration.
