This is a great tool to learn amino acid structures and codes (single letter abbreviations). You will get different types of questions, so the learning process will not be boring. Examples of the questions are:
- what is the structure of Alanine?
- which structure corresponds to amino acid code A?
- what is amino acid code for Alanine?
... and so on!

Statistics of your answers will be collected so you can see which amino acids you haven't learned good enough.
