STUDY OF BIOLOGICAL PROCESSES USING PHYSICAL PRINCIPLES (E.G., PROTEIN FOLDING, MOLECULAR INTERACTIONS)

Abstract

The study of biological processes through physical principles has become a cornerstone in advancing modern biophysics, offering a quantitative framework to unravel complex molecular behaviors. This research investigates fundamental processes such as protein folding, conformational dynamics, and molecular interactions by applying concepts from thermodynamics, statistical mechanics, and quantum physics. Protein folding is examined as a physical process governed by energy landscapes, entropy–enthalpy balance, and kinetic pathways, highlighting the role of misfolding in diseases such as Alzheimer’s and Parkinson’s. Similarly, molecular interactions—including hydrogen bonding, van der Waals forces, and electrostatic potentials—are analyzed through computational models and spectroscopic techniques to elucidate their contributions to cellular stability and function. Advanced methodologies, such as molecular dynamics simulations, single-molecule spectroscopy, and cryo-electron microscopy, are employed to capture dynamic structural changes at atomic resolution. The study emphasizes how integrating physical models with experimental biology not only enhances mechanistic understanding but also provides predictive capabilities for drug design, biomaterials engineering, and synthetic biology. Ultimately, this work underscores the indispensable role of physics in interpreting biological complexity, bridging the gap between molecular mechanisms and functional outcomes in living systems.
