Document Summary

Proteins have many structures, resulting in a wide range of functions. Enzymatic proteins regulate metabolism by acting as catalysts. Catalysts chemical agents that selectively speed up chemical reactions without being consumed by the reaction. An enzyme can perform its function over and over again, so it keep cells running by carrying out the processes of life. Polypeptides polymers of amino acids linked by peptide bonds. A protein consists of one or more polypeptides, each folded and coiled into a specific 3d structure. Amino acids are organic molecules possessing both carboxyl and amino groups. Alpha carbon the centre of the amino acid. An amino acid comprises of an amino group, a carboxyl group, a hydrogen atom, and a variable group (r). The r group is also called the side chain, differs with each amino acid. The physical and chemical properties of the side chain determine the unique characteristics of a particular amino acid, thus affecting its functional role in a polypeptide.
