I submit that beginning A&P students should know a bit about protein folding.
Knowing the very basic principles of protein folding help students visualize the complex shape of proteins. That, in turn, helps them understand that "it's all about shape" when trying to understand how proteins like enzymes, receptors, and most other proteins work—proteins that they'll encounter many times throughout their A&P course and beyond.
Besides that, protein folding has become a key concept in understanding not only how the body functions, but how to intervene therapeutically in important diseases. If a class of therapy based on protein folding is now being developed, a class of therapy that many of our students will likely encounter in their professions, don't we owe it to them to cover the basic ideas of protein folding?
This latest idea was brought up at a recent meeting of the American Society of Cell Biology (ASCB). You may want to read the article below, which briefly summarizes some current work being done in developing drugs that affect protein folding systems. None of the specific information in the article would be appropriate for A&P students to learn. But reading it will give the A&P professor better insights about why the concept of protein folding is important for students to learn. And it gives you a chance to say, "I was just reading about how scientists are now developing drugs based on protein folding . . . " to get their attention in class!
