NCERT Solutions for Class 11 Biology Chapter 9 Biomolecules are given here. Biomolecules or Biological molecules are the naturally occurring and essential components of living organisms. These organic compounds are produced by the cells of the living organisms. Biomolecules are generally composed of molecules of atoms, which are covalently bound together. It mainly comprises carbon and hydrogen along with nitrogen, oxygen, sulfur, and phosphorus.
Carbohydrates, Lipids, Proteins and Nucleic acids are four major classes of biomolecules which play an important role in the maintenance and metabolic processes of living organisms. The structure of these biomolecules is in four different forms- primary, secondary, tertiary and quaternary structure. Among all four biomolecules, proteins make up the majority of biomolecules present in a cell, then followed by the Nucleic acids, carbohydrates and the final class of biomolecules is lipids.
The main functions of biomolecules are:
- Carbohydrates are the main source of fuel and energy. It is involved in proper functioning of our brain, heart and nervous, digestive and immune system.
- Proteins can be antibodies and enzymes which are involved in providing structural support, helps in body movement, and also acts a defense against germs and other infectious agents.
- Lipids are the main sources of energy storage and are involved in the controlling flow of material in and out of the cell.
- Nucleic acids are essential to all known forms of life. DNA and RNA are the two main types of nucleic acids. They are the genetic material found in living organisms, functions by transferring genetic information from parents to their offsprings. They also help in the synthesis of proteins, through the process of translation and transcription.
All biomolecules share a common fundamental relationship between structure and function and are influenced by factors such as the environment.
