On July 29th, I logged in and saw an urgent email. 📮
It was from the Managing Director of a Research Center I consult.
The request was simple:
Who could animate individual molecules joining a polymer network?
I joyfully replied, "I could do it!"
(Wisely) I was asked to provide 3️⃣ examples of molecular animations I'd created.
Confidently, I agreed to create and send these by the end of the month.
But, after sharing a list of colleagues with experience in molecular animation, I set off to learn the skill.
It took 2 months to create this 1, 17-second animation:
But! I think I can shorten the process for others by sharing a step-by-step recreation guide and a bit about what I learned from the experience:
Fellow Visualizers of the Abstract (Chemists),
I animated the dehydration synthesis of maltose in 3D. Here's how:
Tools & Directions
The animation was created using Blender, a free 3D modeling software.
I wrote out my methods step-by-step so that one might recreate what I did which could be revised to animate most chemical reactions:
First, the Software 🖥️
- Blender (Free)
- Blender is a free, open-source 3D modeling and animation software.
- It creates high-quality 3D graphics, animations, and rendering.
- Blender has a steep learning curve but offers various advanced features and tools.
- It is not specifically designed for molecular visualization but can be used for that purpose with the help of add-ons (more below).
- PyMOL (Free for Educational Licensing)
- PyMOL is a popular molecular visualization software used for modeling and visualizing 3D structures of biomolecules, such as proteins, DNA, RNA, and small molecules.
- It can interpret over 30 file formats and offers nearly 20 ways to represent molecular data.
- PyMOL has a straightforward graphical user interface and is well-suited for scientific analysis and creating high-quality molecular images.
- However, PyMOL has limited options for exporting structures and does not preserve color information when exporting (we'll fix that in the step-by-step guide).
- Atomic Blender (Free)
- Atomic Blender is a Blender add-on that bridges the gap between molecular visualization software (VMD and PyMOL) and Blender.
- It allows users to import Protein Data Bank (PDB), VMD Visualization State files, and PyMOL Session files directly into Blender.
- With Atomic Blender, users can create advanced molecular visualizations and animations in Blender, leveraging the powerful features and rendering capabilities of the 3D software.

The Learning Process: More Than Just Animation
I was astounded by how many chemistry topics I had to review and subsequently understood better in the process of animating this one reaction in three dimensions.
🧪 We're talking: Anomers vs. epimers and the anomeric effect, Haworth projections and chair conformations, Chirality and cyclization in glucose, Electron density distribution and steric hindrance, Leaving group ability in dehydration synthesis, Hybridization states and orbital interactions, Alpha/beta face nucleophilic attacks, Enzyme selectivity and substrate specificity, Solvent effects on reactivity and the anomeric effect, and more.
3D Animation & Chemistry
This experience convinced me of the immense potential of 3D animation projects to advance chemistry education and research:
- Assign (or co-create) animation projects to reinforce complex concepts
- Create an animation for your talk or paper
- Use already created animations for peer teaching
- Develop visual aids for lectures and online courses
Your Turn to Explore
I've documented my process and am excited to share it with you. Please feel free to ask questions in the comments section below and share any animations you make with the Collective! We'd love to cheer you on.
Stay tuned for more resources!
