Protein Chemistry: Amino Acids, Folding, and Function

Proteins drive nearly every biological process, from metabolism and signaling to structure and defense. Understanding their chemistry is the gateway to mastering molecular biology and biotechnology. By the end of this course, you will have a deep understanding of protein composition, the non-covalent forces that stabilize their structure, and how changes in sequence can lead to biological dysfunction. You will be prepared to read and analyze foundational texts and research in biochemistry. What you'll learn: * Learn the classification, ionization states, and chemical properties of the twenty common amino acids. * Understand the formation of the peptide bond and the principles governing primary and secondary protein structures. * Analyze the forces (hydrophobic effect, hydrogen bonds, ionic interactions) that stabilize tertiary and quaternary protein structures. * Practice interpreting protein folding pathways and the critical concepts of denaturation and renaturation. * Apply foundational knowledge to understand the principles behind modern protein separation and structural analysis methods. * Master the crucial relationship between protein structure, function, and common misfolding diseases. The course begins by defining the building blocks of life—the amino acids—before systematically exploring the four levels of protein structure and the chemical kinetics of protein folding. Practical examples illustrate how structure dictates function in key biological molecules. This course is designed for absolute beginners, including students starting biochemistry, molecular biology, or biotechnology, who have no prior experience in protein chemistry.
