Molecule World

This year marks the 100th anniversary of crystallography and Digital World Biology is celebrating by releasing our Molecule WorldTM iPad app.  Molecule World teaches the relationships among sequence, structure, and function. 

Traditionally, science educators and their students have had limited access to the computers needed to use the software and databases created over the past 15 years through endeavors like the Human Genome Project. The enormity of searching databases, compiling datasets, installing software, and dealing with constant change make it nearly impossible to develop interesting instructional activities that could be conducted in a the short time frames needed to meet classroom goals.

We've changed the model!  The Molecule World iPad app, literally, puts over a hundred thousand molecular structures at your fingertips. 

Get the Molecule World iPad app today and view thousands of 3D molecular structures.

Teachers & College professors - Please note:  You can get a %50 discount if you buy 20 copies or more, see Apple's Volume Purchasing Program for more details.


  • A set of popular protein, DNA, RNA, and chemical structures for biology teaching that include hemoglobin, antibodies, restriction enzymes, tRNA, caffiene, and more. 
  • View molecular and chemical structures in 3D
  • Manipulate structures easily with your fingertips
  • Color structures by molecule, residue, or chemical properties
