Starch, glycogen and cellulose Flashcards
What is starch made out of
Alpha glucose
What is starch used for
Storage of energy
What are starches features
alpha helix and branched, insoluble large, compact, hydrolyses to form alpha glucose for respiration
Where is starch found?
In plant cells
What do animal cells have instead of starch?
glycogen
What is glycogen used for
Storage
Where is glycogen stored
muscles
What is glycogens features
insoluble, doesnt diffuse out of cells, compact, more branched than starch for faster breakdown
What is cellulose made out of and why
beta glucose for a straighter and unbranched structure
Why is cellulose very strong
It has hydrogen bonds between the polysaccharides, and group together to make microfibrils which group together to form fibres
What is cellulose used for
cell walls for rigidity and to prevent bursting
