Sugars
Carbohydrates are organic compounds of carbon, hydrogen and oxygen in which the ratio of atoms of hydrogen and oxygen is 2:1.
The general molecular formula of carbohydrate is Cx(H2O)y or CxH2yOy
Classification of Carbohydrates
The classification is based on the effect of acid hydrolysis of carbohydrates.
Monosaccharides
These are simple sugars. Examples are glucose and fructose. They cannot be split into simple molecules by acid hydrolysis.
Structure of Glucose and Sucrose
Disaccharides
They are also sugars e.g. sucrose, maltose, and lactose. They can be split into two molecules of monosaccharide by acid hydrolysis.
