6) Proteins are composed of amino acids polymerized into long chains. The structure of a protein - that is, its overall shape and how the chains are "folded” around each other - is very important for its function. In an aqueous environment, in an active, folded state the hydrophilic amino acids in the protein are facing outwards exposed to the water and the hydrophobic amino acids are hidden away from the water in the core of the protein. In a...
