CHARMM (Chemistry at HARvard Molecular Mechanics)

CHARMM (Chemistry at HARvard Molecular Mechanics) is a computational software used by scientists to simulate and study the behavior of biological molecules like proteins and DNA. It models how these molecules move and interact based on their atomic structures and physical forces. By doing so, CHARMM helps researchers understand molecular functions, predict reactions, and design new medicines—all without needing physical experiments. It combines principles of chemistry, physics, and computer science to provide detailed insights into molecular systems at the atomic level.
