We will be using four common amino acids: arginine, glutamic acid, leucine and valine. Each has a structure, which can be represented by where R represents the parts of the structure which are different with each amino acid. The two groups common to all amino acids are the -NH 2 group (the amino group) and the -COOH group (the carboxylic acid ...
