What’s your favourite molecule? ChemJuice Grande lets your finger draw chemical structures and build your own mobile database of molecules.

- Just drag your finger to draw bonds
- Tap on atoms or bonds to delete, change atom symbol or bond type
- Drag a bond to expand and make a ring
- Hold your finger on an atom to move it
- Copy and paste

And why not add some notes so you don’t forget why your molecule is so great? Draw more structures, write the notes and you have your own mobile database of molecules. Arrange your molecules into collections by tagging them. And when you want to share your structure – just email it.

But there’s more, ChemJuice contains a gallery of over a hundred molecules and reactions that we think you will find fascinating and the notes will tell you why. Do you know which molecule makes chocolate so addictive? ChemJuice does. We have seeded the gallery with links to Wikipedia, YouTube videos and documents to show you what is possible in ChemJuice Grande.
