Proteins are one of the four main macromolecules in biology. Protein are made of amino acids, where there are a total of 20 distinct ones with different polarity. Proteins has a start, an N- terminus, and an end, C- terminus. The N- terminus is compose of amines (NH2) and the C- terminus is compose of the carboxyl group (-COOH). The building blocks are linked via a peptide bond, also known as amide bond, via condensation reaction. This macromolecule (proteins) has many function and “are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance” (http://www.nature.com/scitable/topicpage/protein-function-14123348).
