Define bio-molecules and what are the major types or groups you know.

Bio molecules can be defined as the molecules that is synthesized or produced by the cells inside living organism.

Explanation:

Biomolecules have a huge range of size and structure. They perform a variety of function depending on their structure and size.

There are mainly 4 major types of biomolecules: Carbohydrates, nucleic acids, lipids and proteins.

Carbohydrates is the most abundant biomolecule on earth and is made up of carbon, hydrogen and oxygen. It acts a source of energy. Lipids acts a stored energy source and also acts as chemical messenger, also major component of cell membrane. It is made of fatty acid molecules and glycerol. Nucleic acids play a major role in carrying the information from one generation to another and plays a major role in inheritance. Nucleic acid are made of nucleotide. Proteins are the building blocks of the living system and it performs a majority of functions such as it regulates the activity of cell, major component of nails and hair. It is a polymer of amino acids.
