Thermodynamics of Biomolecular Systems: A Foundational Guide

Biological systems are governed by the same energy laws as the physical world. Understanding how these laws apply to molecules like DNA and proteins is essential for biochemistry and biophysics. This course provides a solid foundation in classical thermodynamics, specifically tailored for biological contexts. By the end, you will be able to calculate key thermodynamic quantities and predict the behavior, stability, and binding affinity of biomolecules under various conditions. ### What you'll learn * **Understand** the fundamental laws of thermodynamics and key state functions (enthalpy, entropy, Gibbs free energy) in biological contexts. * **Apply** concepts of chemical potential and equilibrium to analyze biochemical reactions in solution and non-ideal systems. * **Analyze** the thermodynamic driving forces behind biomolecular folding and conformational stability of macromolecules. * **Calculate** binding constants and cooperative effects for molecular interactions, such as protein-ligand binding. * **Practice** using thermodynamic cycles to predict energy changes associated with hydration and non-covalent forces. This course begins with definitions and the laws of thermodynamics, quickly moving into their application to phase transitions and chemical equilibrium. The latter sections focus specifically on macromolecular stability, folding, and interaction dynamics using quantitative methods and written exercises. This course is designed for absolute beginners in biomolecular thermodynamics, requiring no prior expertise in advanced physical chemistry or biology.
