Glycine 
Glycine is the most simple amino acid - its best to just memorize that this important amino acid has a functional group that only contains a hydrogen! 
 
 
 
Alanine 
Alanine has a really simple functional group (just a simple methyl group) that some of the other AA functional groups build on. You can remember the name because the alphabet builds on the letter A and other functional groups build on the simple Alanine R group. What about the other A amino acids? well Alanine has the shor...
