Page 1: Biochemistry Overview

Introduction to Biochemistry

• Biochemistry: The study of chemical processes within and relating to living organisms.

Definition of Macromolecules

• Macromolecules (Biomolecules): Large, complex molecules that are essential for life.

• Consist mainly of carbon, along with other elements such as hydrogen, oxygen, nitrogen, phosphorus, and sulfur.

Types of Macromolecules

• Major classes of macromolecules include:

  • Carbohydrates: Sugars and starches that provide energy and structural support.

  • Proteins: Comprised of amino acids; they perform a wide range of functions including catalyzing reactions (enzymes), transporting molecules, and providing structural support.

  • Lipids: Fats and oils; essential for storing energy and forming cell membranes.

  • Nucleic Acids: DNA and RNA; vital for storing and transmitting genetic information.

Importance of Carbon-Based Molecules

• Carbon: The backbone of macromolecules due to its ability to form four covalent bonds, allowing complex and varied structures essential for life.
