A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino, carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure, there are 4 levels. The first one being the primary level. These are made up of sequences of amino acids and these amino acids are linked together by peptide bonds. The next level is called secondary. This level is a formation of amino acid chains folded together by a helix formation or a pleated sheet. The bonds between
