Carbohydrates 2 - polysaccharides Flashcards
1
Q
what is a polysaccharide?
A
> polymers of monosaccharides
> 100,000s of monomers
2
Q
Why are they good energy stores?
A
> glycogen and starch are compact
glucose can be easily snipped of the end for respiration
less soluble in water meaning WP doesn’t decrease and disrupt the workings of the cell
3
Q
Amylose ( plants )
A
> long chain of alpha glucose molecules
has glycosidic bonds 1 and 4
coils into a spiral shape held together by hydrogen bonds
less soluble
4
Q
Amylopectin ( plants )
A
> glycosidic bonds but branches between carbons 1 and 6
coils into a spiral shape
branches form from spiral
5
Q
Glycogen ( animals )
A
> branches between 1-6
1-4 bonded chains are smaller/less tendency to coil
more compact cus of more branches
easier to remove monomer umits
