Amino acids are important building blocks; they play an essential role in the formation of proteins and as intermediates in metabolism. Amino acids can serve as cell signaling molecules and can regulate gene expression. An optimal amount of amino acids is essential for health. There are over 500 amino acids‚ however only 20 are commonly found. Amino acids all have an amine functional group and a carboxylic acid functional group. They differentiate from each other in their side chains. Only 10 of
