What are the products of hydrolysis of sugar?

Sugar is the generalized name for sweet, short-chain, soluble carbohydrates, most of these are used in food. They are carbohydrates, made up of of carbon, hydrogen, and oxygen. There are various types of sugar derived from different sources. Simple sugars are called monosaccharides and include glucose (also known as dextrose), fructose and galactose. The table or granulated sugar most customarily used as food is sucrose, a disaccharide. (In the body, sucrose hydrolyses into fructose and glucose.) Other disaccharides include maltose and lactose. Longer chains of sugars are called oligosaccharides.

The hydrolysis products of sugar are different for different type of sugar.
For example on hydrolysis of sucrose, the products obtained are glucose and fructose.
