Welcome! We specialize in custom designed molecular animations (for stand-alone use or integrated into a molecular tour or tutorial) and interactive versions of print media molecular figures.
Animations & Tutorials
Looking for fully interactive, online animations? You've found them. Molecules in Motion has been providing animations of molecules in 3D that are scientifically accurate, beautiful, and clear for over 10 years. Our animations are being featured at the web sites of leading textbooks and journals, in films, and on television. Custom design is our specialty.
Interacting with our animations is as easy as clicking the mouse. Just click and drag to rotate in 3D, click and SHIFT-drag to zoom.
What are Proteins? • View Animation
Composed of twenty different building blocks called amino acids, proteins are the most versatile molecules in biology. Three different proteins illustrate common structural elements of proteins despite their very different functions.
Opsins • View Animation
Take a tour of the proteins that enable the photoreceptor cells of the eye to detect light. Developed with Bruce Patterson of the University of Arizona.
Custom Animation Design
Our custom animations are suitable for web delivery, film or video. They have appeared on the National Geographic Channel and in the documentary film, "Flock of Dodos", as supplements to textbooks including Lehninger's Principles of Biochemistry, Stryer's Biochemistry and others. They can be used for supplementing research publications, teaching, presentations, 3D illustration, or any eye-catching purpose you have in mind. For more information, contact us.
Interactive 3D Figures
Journal Figures Come to Life in 3D
Molecules in Motion figures appear in select Biochemical Journal Reviews. Each interactive, animated figure opens with an exact replica of a print figure in the review, and is supplemented with a control panel to explore the structure at will.

3D Interactive Figures Comparison
Compare still figures and the interactive replicas, side-by-side.
Any molecular structure figure can be adapted for viewing in 3D on a web page. There is no need to install any software for viewing them. They appear in ordinary web pages.
For more information, view our flyer, or send an emai with your enquiry to email@example.com.
Chime tutorials use an outdated technology and are available here for the die-hard Chime users out there.
To view Chime tutorials, you must use Netscape 4.5 - 4.7 (yikes!!) and have the Chime plug-in installed. Hundreds of Chime tutorials are still on the web, many accessible through the World Index of Molecular Visualization. For more information on Chime, visit MolviZ.Org.
An interactive tour for everyone - take a look around a DNA helix! Investigate its nooks and crannies by zooming in and out with the mouse, and turning it this way and that. Click on buttons to watch animations that show off important features of DNA. Includes a version translated to Italian.
DNA & the Double Helix
Designed for classroom presentations, illustrates the fundamentals of nucleotide and double helix structure.
DNA Binding Motifs
In order for the genetic code to be "read" correctly, proteins that attach themselves to DNA are essential. Here are three examples of themes (or "motifs") common to proteins that bind and regulate DNA: the zinc finger, helix-loop-helix, and leucine zipper. Use the buttons to change the colors and representations of the DNA and proteins-- see for yourself how the proteins cling to DNA. Lecture-ready: buttons are labelled with keywords.
Protein Secondary Structure 3.0
The alpha helix and beta sheet are explored in terms of stabilizing forces and interactions within proteins. Includes many hyperlinked definitions of biochemical terms, and questions for discussion. Also available as adapted by Worth Publishing at the Lehninger Biochemistry in 3D web site, where it includes an additional section on beta-turns. (Follow links to "Protein Architechture".) Lecture-ready versions of the alpha-helix and beta sheet are also available.
Protein Secondary Structure 2.0
An overview of the of stabilizing forces, hydrogen bonds, and hydrophobic interactions that characterize protein secondary structures.
Protein Secondary Structure 1.0
For presentation use in a classroom lecture. Movie buttons are labelled with key words instead of textual explanations. The movies allow time for an instructor to narrate.
