What is a Biomolecule?

Biomolecules are naturally occurring organic molecules that are essential for life. They are the building blocks of living organisms and are involved in all biological processes.


🔹 Definition:

Biomolecules are chemical compounds found in living organisms that are mainly made up of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S).


🔹 Major Types of Biomolecules:

  1. Carbohydrates
    🔸 Function: Provide energy
    🔸 Example: Glucose, Starch

  2. Proteins
    🔸 Function: Build and repair tissues, enzymes, hormones
    🔸 Example: Hemoglobin, Insulin

  3. Lipids (Fats and Oils)
    🔸 Function: Store energy, make cell membranes
    🔸 Example: Cholesterol, Triglycerides

  4. Nucleic Acids
    🔸 Function: Store genetic information
    🔸 Example: DNA (Deoxyribonucleic acid), RNA (Ribonucleic acid)


🔹 Other Important Biomolecules:

  • Vitamins – Help in metabolic processes
  • Hormones – Regulate body functions
  • Enzymes – Speed up biochemical reactions

🔹 Examples in Daily Life:

Biomolecule Type Example Found In
Carbohydrate Glucose Fruits, rice, bread
Protein Albumin Eggs, meat, milk
Lipid Butter (fat) Dairy, oils, nuts
Nucleic Acid DNA, RNA Present in all living cells

Let me know if you want this in Hindi, or need Class 12 notes on this topic.
