Carbohydrates are ?
Large complex molecules composed of long chains of monosaccharides
1 of 18
How are the OH, placed on a alpha-glucose molecule ?
below, below, above, below
2 of 18
How are monosaccharides joined ?
By a glycosidic bond
3 of 18
How is a disaccharide formed ?
When two monosaccharides join together
4 of 18
How is a polysaccharide formed ?
When more than two monosaccharides join together
5 of 18
What is starch ?
A energy storage molecule in plants
6 of 18
What two alpha-glucose polysaccharides are in starch ?
Amylose and Amylopectin
7 of 18
Is amylose a long unbranched chain of alpha glucose ?
True
8 of 18
What properties does Amylose have ?
It is compact, meaning it is a good storage as alot can be fit into a small space
9 of 18
How is Amylopectin different to Amylose ?
It is branched
10 of 18
What do branches allow in a polysaccharide ?
Allows enzymes to break down the molecule, to get to the glycosidic bonds easily means it can be released quickly
11 of 18
Is starch insoluble ?
True
12 of 18
What is glycogen ?
It is the main energy storage molecule in animals
13 of 18
Glycogen is a polysaccharide of what glucose ?
Alpha
14 of 18
Is glycogen branced ?
True
15 of 18
What is cellulose ?
It is the major component of cell walls in plants
16 of 18
Describe the polysaccharide chain of cellulose ?
Unbranched, beta glucose
17 of 18
What bonds form between the chains of cellulose ?
Hydrogen
