Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.
Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.
Students explore both 2D and 3D models of proteins in order to discern the structure of a small protein, the hormone insulin. They connect the structure to its triggering function at a receptor site for the hormone.
Students will be able to:
The insulin protein molecule is characterized by its folding, which is the result of several types of attractions. Write a short paragraph explaining why three different types of attractions are important to the structure and function of the molecule.
There are tens of thousands of different kinds of proteins. Each one has a unique shape and its 3D structure corresponds to its function. The sequence of amino acids, their interactions, and the interactions with the surrounding environment are explored in this activity. Students can explore the four levels of protein structure using 2D and 3D models.
The three or four-tiered structure of proteins is related to their function.
