|
What are the two types of starch? |
Amylose and amylopectin. |
|
|
How is amylose adapted to its function? |
It is coiled, making it compact for storage. Also insoluble so doesn't affect water potential. |
|
|
How is amylopectin adapted to its function? |
Is a branched chain, giving a larger surface area allowing for quicker hydrolysis. Also insoluble so doesn't affect water potential. |
