Molecular Origami - the concept

Molecular Origami is an outgrowth of 'Data-Driven Chemistry', a technique of teaching chemistry under development by Prof. Bob Hanson at St. Olaf College, in Northfield, Minnesota.

Molecular Origami refers to the detailed folding and arrangement of atoms in molecules and network solids. Molecular Origami by Robert M. Hanson (University Science Books) is a set of actual paper models focusing on small organic and inorganic structures. Data are based primarily on electron and x-ray diffraction results. Discussion of the models in terms of bonding and qualitative molecular orbital theory is included. Exact interatomic distances and angles are indicated on these figures. They can be folded to produce three-dimensional scale models of molecules or sections of molecules.

Molecular Origami - the PC program DOWNLOAD

The program Molecular Origami allows you to print most of the structures in the book. In addition, you can investigate molecular structure on your own, using data that you might have access to. The program has an option to retrieve data directly from the internet. Some databases that can be freely accessed include: Brookhaven's Protein Data Bank, SWISS-MODEL Repository, and Indiana University Molecular Structure Center.
There is not a Mac Version of Molecular Origami.

Why Use Molecular Origami ?

The computer program originated with the idea of producing paper scale models of proteins. As we looked for other protein computer modelers it became evident that the real value of the program was not just the origami, but also the computer modeling capabilities. Other protein modeling programs exist such as RasMol. For a task such as showing the entire protein structure RasMol does a great job. In fact if you have RasMol, Molecular Origami has a button that displays the current protein with RasMol. Molecular Origami is unique because it enables you to pick and choose what groups you want to look at. This is useful because many proteins have hundreds of amino acids and get extremely complicated to view in their entirety.

With Molecular Origami you can view only the parts of the protein you are interested in. It is easy, all you have to do is select the groups you want to appear from a list. They appear on the screen where they can be rotated by moving the mouse.
