What are monosaccharides?

Hint: Carbohydrates are organic molecules made of Carbon, hydrogen and oxygen molecules. They are connected to each other by special bonds. These bonds between two carbohydrate molecules release water and follow the mechanism of condensation bonds.

Complete step by step answer:
Carbohydrates are a form of polymer which are commonly known as sugars. They are polymers whose constituent units are joined together by glycosidic bonds that form a bond between two monomeric units when water is released. The carbohydrates can be divided into different groups depending on the number of monomers that combine to form a carbohydrate. The simplest form of a carbohydrate chain is the monosaccharide which are also known as simple sugars.
These molecules are usually considered as the monomers of a carbohydrate chain since they are present in a single unit and are not attached to any other monosaccharide.
The other groups are oligosaccharides and polysaccharides. The oligosaccharides are the chain of monosaccharides that consist of few monosaccharides that are usually three to ten monomeric units. Polysaccharides usually consist of more than ten units. They are long chain carbohydrates that are more complex. A few examples of monosaccharides are glucose and fructose. Maltose and lactose are examples for oligosaccharides. An example for polysaccharides is starch and glycogen. Polysaccharides are mostly used as storage carbohydrates. The monosaccharides can release energy upon locomotion or performance of any type of work.

Note: Monosaccharides are the simplest unit of carbohydrates. They are the basis of formation of long chain carbohydrates like oligosaccharides and polysaccharides. They are sources of instant energy in the body and play an important role in carrying out the different activities in the body.
