Micro and Macromolecules in Biochemistry
Key Points

  • Monomers: Small molecules that are the basic building blocks of macromolecules.
  • Macromolecules: Large, complex molecules composed of many monomers linked together through covalent bonds.
  • Microorganisms: Living organisms that are too small to be seen with the naked eye.
  • Biochemistry: The study of the chemical composition and reactions of living matter.

Main Concepts

Monomers


Monomers are the basic building blocks of macromolecules. They are small molecules that can be joined together in many different ways to create a wide variety of macromolecules.


Macromolecules


Macromolecules are large, complex molecules composed of many monomers linked together through covalent bonds. Macromolecules can be found in all living organisms and perform a variety of functions, such as structural support, energy storage, and cell signaling.


Microorganisms


Microorganisms are living organisms that are too small to be seen with the naked eye. Microorganisms can be found in all environments on Earth and play a vital role in the cycling of nutrients and the decomposition of organic matter.


Biochemistry


Biochemistry is the study of the chemical composition and reactions of living matter. Biochemistry seeks to understand how living organisms function at the molecular level.



Micro and Macromolecules in Biochemistry Experiment
Objective:

To demonstrate the different properties of micro and macromolecules and their interactions.


Materials:

  • Iodine solution
  • Starch solution
  • Glucose solution
  • Sucrose solution
  • Test tubes
  • Pipettes

Procedure:

  1. Add 1 mL of iodine solution to separate test tubes containing 1 mL of starch solution, glucose solution, and sucrose solution.
  2. Observe the color changes in each test tube.
  3. Pipette 1 mL of starch solution into a test tube and add 1 drop of iodine solution.
  4. Observe the color change and compare it to the color changes in the previous step.

Key Procedures:

  • The iodine solution reacts with starch to form a dark blue-black complex.
  • Small molecules like glucose and sucrose do not react with iodine and will not show a color change.
  • Starch is a macromolecule, while glucose and sucrose are micromolecules.

Significance:

This experiment demonstrates the different properties of micro and macromolecules and their interactions. It can help students understand the role of macromolecules in biological systems.
