Dynamic structural alterations in molecules, particularly proteins and other biomolecules, that modify their shape, function, and interactions with other molecules.

Conformational Changes

Conformational changes represent the dynamic structural modifications that molecules undergo, fundamentally altering their three-dimensional arrangement while maintaining their primary chemical composition. These changes are particularly crucial in protein folding and molecular recognition processes.

Mechanisms and Drivers

Several factors can trigger conformational changes:

pH fluctuations
Temperature variations
ionic strength changes
Presence of specific ligands

Energy Landscapes The process follows complex energy landscapes characterized by:

Multiple stable states
Energy barriers between conformations
thermodynamic equilibrium considerations
