Analysis
Applications
- Protein folding: Predict 3D structure from sequence
- Drug binding: Test small molecules against target
- Membrane dynamics: Lipid bilayer behavior
- Molecular machines: Kinesin, myosin motors
- ⚠️ Molecular assemblers: Future nanotech design
Timescales:
- Vibrations: femtoseconds
- Side chain motion: picoseconds
- Protein folding: microseconds-milliseconds
- Requires massive compute for biologically relevant timescales
