Introduction to Peptide Folding Simulation
Peptide folding simulation, bridging sequence and conformation, advances through collaboration between computational biology and experimental technology. Peptide folding simulation has evolved from simple coarse-grained models to multi-scale approaches integrating force fields and machine learning, revealing the physical and chemical nature of folding and promoting the development of drug design, disease mechanism analysis, and synthetic biology.

Hierarchical Strategies for Multi-scale Peptide Folding Simulation
To balance computational accuracy and efficiency, peptide folding simulation uses multi-scale strategies from all-atom to coarse-grained:
Utilize All-Atom Force Fields
Accurately characterize non-bonded interactions between atoms (van der Waals forces, electrostatics, hydrogen bonds), suitable for mechanism analysis of microsecond folding trajectories (such as folding free energy surface calculation of Trp-cage mini-proteins).
Construct Coarse-Grained Models
Simplify multiple atoms into a single "bead", and significantly improve sampling efficiency, especially for long peptides (such as transmembrane domains) or multi-domain protein folding studies in membrane environments (such as multi-helix cooperative folding of lysozyme).
Employ Enhanced Sampling Methods
Overcome the energy barrier crossing problem by modifying the potential energy function or parallel multi-temperature simulation. For example, replica exchange Gaussian accelerated molecular dynamics (REX-GaMD) can simultaneously capture folding intermediates and transition states, revealing the folding-unfolding equilibrium of peptides.
