One type of interaction that plays a major role in the correct folding of a protein is the hydrophobic interaction. The properties of amino acids also influence the tertiary structure or overall shape of the protein. The polar and charged amino acids are hydrophilic and can dissolve in water, whereas the nonpolar amino acids are hydrophobic and do not dissolve in water. They can be polar, nonpolar, or charged, and this gives rise to amino acids with varying physical properties. The side chains of amino acids are often called R groups. While the secondary structure is formed by interactions between the backbone constituents, the tertiary structure is the overall three-dimensional shape that is formed by the interactions of the side chains of the various amino acids. Quaternary structure is the association between two or more polypeptides, but not every protein has a quaternary structure. Tertiary structure is the three-dimensional shape of the protein determined by regions stabilized by interactions between the side chains. Secondary structure is comprised of regions stabilized by hydrogen bonds between atoms in the polypeptide backbone. In brief, primary structure is the linear chain of amino acids. Every protein can be described according to its primary structure, secondary structure, tertiary structure, and quaternary structure is present. By forming peptide bonds between the amino and carboxyl groups on two different amino acids, large polypeptide chains can be created. As diverse as they can be, they are all made up of the same 20 amino acids. They are known as the most structurally complicated biological molecules. Each of these proteins has its structure and function. A human has tens of thousands of proteins in their body at any given moment in time. Different proteins can play a role in speeding up chemical reactions, storage, defense, cell communication, movement, and structural support. There are many different types of proteins. They account for 50% of the dry mass of cells and play a role in everything an organism does. Nearly every function in living beings depends on proteins.
