The Fate of Fat

More About Fate of Fat

An overview of how dietary fat gets digested, packaged, and sent to various tissues for storage or energy. 

Fate of Fat Background

Protein, carbohydrate, and fat all have their own pathways for metabolism. In the case of fat, it is separated from protein and carbohydrates through the initial digestion process in the stomach. Then, in the small intestine, it is absorbed through the microvilli and is repackaged into a delivery particle called a chylomicron. These chylomicrons travel through the lymphatic system and are delivered to fat cells for storage, or to muscle cells for energy. From Lecture Two of the 2004 Holiday Lectures Series "The Science of Fat."

Fate of Fat Teaching Tips

The animations in this section have a wide variety of classroom applications. Use the tips below to get started but look for more specific teaching tips in the near future. Please tell us how you are using the animations in your classroom by sending e-mail to biointeractive@hhmi.org.

  1. Use the animations to make abstract scientific ideas visible and concrete.
  2. Explain important scientific principles through the animations. For example, the biological clocks animations can be used to demonstrate the fundamentals of transcription and translation.
  3. Make sure that students learn the material by repeating sections of the animations as often as you think necessary to reinforce underlying scientific principles. You can start, restart, and play back sections of the animations.
  4. Urge students to use the animations in accordance with their own learning styles. Students who are more visually oriented can watch the animations first and read the text later, while others might prefer to read the explanations first and then view the graphics.
  5. Incorporate the animations into Web-based learning modules that you create to supplement your classroom curricula.
  6. Encourage students to incorporate the animations into their own Web-based projects.
