Polysaccharides

How are polysaccharides formed?
Polysaccharides are formed by condensation of many glucose units.
1 of 10
What monomer forms both glycogen and starch?
The monomer is alpha glucose
2 of 10
What monomer forms cellulose?
The monomer is beta glucose
3 of 10
What bond are Monosaccharides joined together by?
Monosaccharides are joined together by glycosidic bonds
4 of 10
Describe the structure of STARCH
Can be branched or unbranched. Unbranched chain is wound in tight compact coil
5 of 10
How does the structure of starch relate to its function (storage)?
Branched= many places for enzymes to break down therefore quicker production of glucose. INSOLUBLE= doesn't diffuse out of cells+ doesn't draw in water by osmosis. COMPACT= lots stored in small space.
6 of 10
Describe the structure of glycogen
Shorter and more highly branched than starch. Stored in small granules

How does the structure of glycogen relate to its function (storage)?
Highly branched= many places for enzymes to break down therefore quicker production of glucose. INSOLUBLE= doesn't diffuse out of cells+ doesn't draw in water by osmosis. COMPACT= lots stored in small space.
8 of 10
Describe the structure of cellulose
Straight unbranched chains. Many Hydrogen bonds.
9 of 10
How does the structure of cellulose relate to its function?
Many H bonds= strong. Parallel, unbranched= strong. Chains group to form microfibrils= stronger. Microfibrils group to form fibres= strongest.
