2How to play
Tap to pull it apart. Hands-on: pull a helix out of the fold; let go and it folds back.

4About it
Proteins are the tiny machines of living things. Each is a long chain of building blocks called amino acids that folds up into its own shape: coils called helices, flat strands and loops. Hemoglobin carries oxygen in the blood, insulin helps control sugar, and a jellyfish protein, GFP, glows green.
These are real shapes from the Protein Data Bank, a free library of well over 200,000 structures that scientists share. Tap it to pull it apart into its pieces, and they come back by themselves; tap again while it is apart and they come back at once. In GFP the glowing part lights up while it is open. You can open any PDB or mmCIF file from the library in the Splash tab.
