(b) Name two types of carbohydrates and give one example of each type
(a) What is a carbohydrate?
A carbohydrate is an organic compound containing carbon, hydrogen and oxygen, in which the hydrogen and oxygen are usually present in the ratio 2 : 1 (the same ratio as in water). Carbohydrates have the general formula Cx(H2O)y and are polyhydroxy aldehydes or ketones (or compounds that yield them on hydrolysis).
(b) Two types of carbohydrates with one example of each
Type
Example
Monosaccharide
Glucose (or fructose)
Disaccharide
Sucrose (or maltose)
Polysaccharide

Any two types with their correct examples are acceptable.
