What are three types of carbohydrates?
Monosacharides, disacharides, and polysacharides.
Monosacharides are the building unit and they have carbon, hydrogen and oxygen in the ratio of 1:2:1. The number of carbon atoms can be between 3 and 9, but the most abundant ones which are found in nature are the hexoses and the pentoses, meaning they have five or six carbons.
The disacharides are made of two monosacharides conneted together.
The polysacharides are made of many monosacharides.
Examples of monosacharides are glucose , fructose, galactose and ribose.
Examples of disacharides are sucrose, maltose, and lactose.
Examples of polysacharides are starch and glycogen.
