Biomolecules

Download Q&A

This chapter explores the structure, function, and importance of biomolecules in living organisms. It is a core topic in school and undergraduate chemistry/biology, essential for Class 11–12 students, NEET aspirants, and undergraduate learners, bridging the understanding of chemistry with biological systems.

In this section, you will study:

  • Classification of biomolecules: carbohydrates, proteins, lipids, nucleic acids

  • Structure, properties, and biological functions of each class

  • Enzymes and their catalytic mechanisms

  • Vitamins and coenzymes and their role in metabolism

  • Hormones and biologically active molecules

  • Structure-function relationship of macromolecules

  • NCERT-aligned explanations, diagrams, MCQs, and exam-oriented questions

The content is structured to build conceptual clarity, improve application understanding, and prepare students for school examinations, NEET, and undergraduate assessments.

Develop a strong foundation in biomolecular chemistry to understand the chemical basis of life, metabolism, and biological regulation.
