Biochemical Applications of Organic Chemistry
Key Points

  • Organic chemistry provides the foundation for understanding the structure and function of biomolecules.
  • Biomolecules include carbohydrates, proteins, nucleic acids, and lipids.
  • Organic chemistry is essential for studying enzyme catalysis, metabolism, and molecular biology.

Main Concepts

Organic chemistry is the study of carbon-containing compounds. Biomolecules are organic molecules that are essential for life. They include carbohydrates, proteins, nucleic acids, and lipids.


Carbohydrates are the body's main source of energy. They are made up of simple sugars, such as glucose, fructose, and galactose. Proteins are made up of amino acids and are essential for building and repairing tissues.


Nucleic acids are made up of nucleotides and are responsible for storing and transmitting genetic information. Lipids are a diverse group of compounds that include fats, oils, and waxes. They are responsible for storing energy and providing insulation.


Organic chemistry is essential for studying the structure and function of biomolecules. It is also used to develop drugs, vaccines, and other medical treatments.


Biochemical Applications of Organic Chemistry: Enzyme Catalysis Experiment
Purpose:

  • Observe the catalytic activity of an enzyme (α-amylase) on a substrate (starch).

Materials:

  • α-Amylase solution
  • Starch solution
  • Iodine solution
  • Test tubes
  • Water bath
  • Stopwatch

Procedure:

  1. Label four test tubes as Control, Enzyme, +Enzyme, and +Inhibitor.
  2. In the Control tube, add 2 mL of starch solution and 1 mL of water.
  3. In the Enzyme tube, add 2 mL of starch solution, 1 mL of α-amylase solution, and 1 mL of water.
  4. In the +Enzyme tube, add 2 mL of starch solution, 1 mL of α-amylase solution, and 1 mL of water.
  5. In the +Inhibitor tube, add 2 mL of starch solution, 1 mL of α-amylase solution, 1 mL of water, and 1 mL of iodine solution.
  6. Place the test tubes in a water bath at 35-40 °C.
  7. Every 30 seconds, record the time and appearance of each test tube.
  8. Continue recording until a clear color change is observed in the Enzyme tube.

Key Procedures:

  • Enzyme Incubation: Incubate the Enzyme and +Enzyme test tubes with the substrate at a suitable temperature to allow the enzyme to work.
  • Iodine Test: Add iodine solution as an indicator to detect the presence of starch. Iodine reacts with starch to form a dark blue-black complex.
  • Control Tube: This tube serves as a reference point to compare the catalytic activity of the enzyme.
  • +Inhibitor Tube: This tube demonstrates the effect of an inhibitor (iodine) on enzyme activity.

Significance:

  • The experiment demonstrates the importance of enzymes in biochemical reactions. Enzymes are biological catalysts that accelerate specific chemical reactions in living organisms.
  • It shows how enzymes interact with substrates to break them down or modify them.
  • The iodine test visualizes the breakdown of starch, indicating the activity of the enzyme α-amylase.
  • The +Inhibitor tube highlights the concept of enzyme inhibition, which can modulate enzyme activity.
  • This experiment has applications in various fields, such as food chemistry, medicine, and biotechnology, where enzymes play crucial roles.
