Two types of monosaccharides
1.ALDOSE
- Carbonyl group is located on the terminal carbon in the chain
2. KETOSE
- Carbonyl group is located on a carbon that is not on the end of the chain
-Glucose, galactose and fructose are all 6 carbon sugars with the chemical formula : C6H12O6
-Glucose and galactose are both aldoses,but fructose is a ketose
