Biomolecules - The Universal Building Blocks of Life
The module explores the fundamental principles that all living organisms are composed of biomolecules, including carbohydrates, proteins, nucleic acids, and lipids. Each biomolecule class is described in terms of its structure, function, and the processes of polymerization and depolymerization. The chapter emphasizes how these biomolecules demonstrate the unity and diversity of life through their molecular architecture and roles in biological processes.

What we have learnt
- All forms of life share a common chemical foundation consisting of biomolecules.
- Biomolecules can form large and complex structures from simpler monomeric units.
- The four major classes of biomolecules are carbohydrates, proteins, nucleic acids, and lipids, each fulfilling vital roles in living organisms.
Key Concepts
- -- Biomolecules
- Organic molecules primarily formed from carbon, which are essential for life.
- -- Polymerization
- The process by which monomers are chemically bonded to form polymers.
- -- Monomer
- A small, repeating unit that serves as the building block for larger structures (polymers).
- -- Carbohydrates
- Biomolecules primarily serving as energy sources and structural components.
- -- Proteins
- Diverse molecules that perform a variety of functions in biological systems including catalysis, structure, and transport.
- -- Nucleic Acids
- Biomolecules that carry genetic information and are involved in the synthesis of proteins.
- -- Lipids
- A diverse class of biomolecules that are hydrophobic and play roles in energy storage, membranes, and signaling.
