Revision cards for carbohydrates

HideShow resource information
Sucrose, fructose and glucose are monosaccharides. What properties do they have?
Monosaccharides are soluble in water, sweet tasting and form crystals.
1 of 10
What is the structural difference between alpha-glucose and beta-glucose?
In alpha-glucose, the H at C1 is above the plane of the ring. In beta-glucose, the H at C1 is below the plane of the ring.
2 of 10
What bond forms between two monosaccharide molecules?
A glycosidic bond, this forms a disaccharide.
3 of 10
What is required in order for the glycosidic bond to be broken?
Water in order for a hydrolysis reaction to take place, and enzymes to catalyse the reaction.`
4 of 10
What is the equation showing the condensation reaction to produce maltose?
C6H6O3 + C6H12O6 -> C12H22O11 + H2O
5 of 10
What are the differences between amylopectin and amylose?
Amylose is coiled by hydrogen bonding which makes it compact, amylopectin is not. Amylopectin is branched, amylose is not. The glycosidic bond in amylose is between carbons 1 and 4, but in amylopectin is between carbons 1 and 6.
6 of 10
What is starch and where is it stored?
Starch is the energy store in plants. It is stored in chloroplasts and membrane-bound starch grains.
7 of 10
What is the molecular formula of pentose sugar?
C5H10O5
8 of 10
Can starch and glycogen dissolve in water?
No. Therefore they do not affect the water potential of cells.
9 of 10
Are glycogen and starch made up of alpha-glucose or beta-glucose?
Alpha-glucose
