Chapter 19 Aminoacids and Proteins

Chapter 19 Aminoacids and Proteins. Amino acids are the building blocks of proteins; they contain a carboxylic acid group and an amino group on the alpha ( ) carbon, the carbon adjacent to the C=O; because they have both a weak acid and weak base present, they actually exist as a salt;
