Organic Molecules

Imagine everything in your body is made of tiny building blocks. Organic molecules are like those essential building blocks that come together to form all living things!

  • Other Names: You might not hear other names for organic molecules very often in everyday conversation, but scientists sometimes call them carbon-based molecules.

What are organic molecules made of?

  • Mostly carbon atoms, but they can also include hydrogen, oxygen, nitrogen, and other elements.
  • These atoms bond together in different shapes and sizes, creating a huge variety of organic molecules.

What do organic molecules do?

  • They are the foundation for all the important things in your body, like:
    • Proteins: The building blocks for your muscles, hair, and skin.
    • Carbohydrates: Your body’s fuel source for energy.
    • Fats: Provide energy storage and insulation.
    • DNA: The instruction manual for your body.

Organic Molecules vs. Vitamins and Minerals

  • Vitamins and minerals are specific types of organic molecules that your body needs in small amounts to function properly. You typically get them from food.
  • Organic molecules is a broader category that includes vitamins, minerals, and many other types of molecules found in living things.

Etymology (Word Origins)

  • “Organic” comes from the Greek word “organon,” which means “instrument” or “tool.”
  • Originally, the term “organic” referred to anything derived from living organisms.
  • Over time, the scientific definition narrowed down to molecules that typically contain carbon and come from living things.
