Learn or review the 20 amino acids.
This app displays the structure of amino acids and asks the user to give the name, as well as the one and three letter abbreviations. The acids displayed are 'almost random', with missed(incorrect) acids being put aside and displayed more often than others.

Why is this app so Tiny?
We value efficiency, and know others do as well. That's why we strive to make apps that are as fully functional yet much easier on storage space than others.

Note to users:
When the NextAcid button is pressed, without pressing the CheckAll button first, that acid will be counted as correct. This is so that you can skip acids for which you are very confident about naming. Similarly, if you do not know an answer, fill in what you DO know and press the CheckAll button to get feedback, including the correct name and abbreviations.
