What is the monomer of Starch
alpha glucose
What are the bonds between starch monomers
1-4 glycosidic bonds in amylose 1-4 and 1-6 in amylopectin
What is the function of Starch
Store glucose
What is the location of Starch
Plant Cells e.g chloroplast
What is the structure of Starch
Made of 2 polymers
Amylose - an unbranched helix
Amylopectin - a branched molecule
How does the structure of starch lead to its function
Helix can compact to fit a lot of glucose in a small space and its branched structure increases surface area for rapid hydrolysis back to glucose.
Insoluble
What are the monomers of Cellulose
Beta Glucose
What are the bonds between cellulose monomers
1-4 glycosidic bonds
What is the function of cellulose
Structural strength for plant cell wall
Location of cellulose
Cell wall
What is the structure of cellulose
Polymer forms long, straight chains.
Chains are held in parallel by many hydrogen bonds to form fibrils. Macro fibrils combine to form a cellulose fiber
How does the the structure of cellulose leads to its function
Many hydrogen bonds provide collective strength
Insoluble
