Amino acid summary - perfect paragraph

Amino acids are the primary building blocks of all proteins. Each amino acid is comprised of a central alpha carbon with an alpha hydrogen, an amino group, a carboxyl group, and a variable R-group that makes them unique. The amino end is referred to as the N-terminus, and the carboxyl end Is referred to as the C-terminus. A total of twenty common amino acids exist within our bodies and they are sorted into different groups based on their chemical properties. For example, polar amino acids are considered to be hydrophilic (water loving) because their R-groups will interact with other polar molecules, including water. Amino acids polymerize with one another via a dehydration reaction and form a polypeptide chain comprised of anywhere from forty to thousands of these tiny building blocks. This is known as the primary structure of a protein.The aforementioned chemical properties of amino acids dictate how the primary structure will fold in an aqueous environment. Since the structure and shape of a protein is dependant on these R-group interactions and protein function is facilitated by shape, it is important that they fold properly. Therefore, the specific position of a given amino acid in the polypeptide is crucial for protein formation. Proteins cannot exist without amino acids and we cannot exist without proteins; amino acids are fundamental components of life itself.
