Amino Acids Found in Proteins • Amino acids contain two functional groups, an amino group (-NH2) and a carboxyl group (-COOH) which are formed on a carboxylic acid. o Alpha amino acids are those where both functional groups are attached to the same carbon. o Side chain/R group and hydrogen atom are also attached to alpha carbon.  Side chain determines the properties of amino acids and its functions. Terminology • There are a variety of different types of amino acids, however the MCA...
