Any tips on memorising and being able to recognise the different types of amino acids? I have categorised into 5 sets: 1. Positively charged amino acids 2. Negatively charged amino acids 3. Polar, uncharged amino acids 4. Non-polar, aliphatic amino acids 5. Aromatic amino acids I have categorised all the AA’s under each category (won’t write on here as it’s far too long). Has anyone discovered any good techniques to be able to remember all of the amino acids?
