In this module, you will learn about the hierarchical nature of protein structure, Ramachandran plot, and protein purification techniques. The Ramachandran plot is a plot of the torsional angles, phi (φ)and psi (ψ) and of the residues (amino acids) contained in a peptide. You will also be introduced to enzymes and its kinetics, enzyme-catalyzed reactions, and protease; an enzyme that catalyzes the breakdown of proteins into smaller polypeptides.
An enzyme is a protein that acts as a catalyst in living organisms. It regulates the rate at which chemical reactions proceed within the living cells, without itself being altered in the process. The biological processes that occur within all living organisms are chemical reactions, and enzymes regulate most of these. In this course, you will be introduced to enzymes and their structure and functioning. You will learn about the mechanism of enzyme-catalysed reactions.
