Biochemistry

Study of chemical processes within and relating to living organisms.

Basic Concepts

Biomolecules: The Building Blocks of Life

What Are Biomolecules?

Biomolecules are special molecules that make up living things. They include carbohydrates, proteins, lipids, and nucleic acids—all vital for life! Each type of biomolecule plays a unique part, from storing energy to carrying genetic information.

Types of Biomolecules

  • Carbohydrates: These are sugars and starches that provide energy.
  • Proteins: Made from amino acids, proteins do everything from building muscles to speeding up chemical reactions.
  • Lipids: Fats and oils, these store energy and make up cell membranes.
  • Nucleic Acids: DNA and RNA, which hold and transmit genetic information.

Where Do We Find Them?

Every cell, from tiny bacteria to giant trees, is packed with these molecules!

Why Are Biomolecules Important?

Without biomolecules, life could not exist. They form the structure, energy source, and instructions needed for living things to grow and function.

Examples

  • Glucose is a carbohydrate that provides quick energy in our bodies.

  • Hemoglobin is a protein that transports oxygen in blood.

In a Nutshell

Biomolecules are the essential molecules that make up all living things.
