Molecular Mechanics Calculation Service
Molecular mechanics calculations provide an efficient computational approach for studying molecular structures and interactions in biological and chemical systems. CD ComputaBio's molecular mechanics calculation service offers robust solutions for researchers requiring reliable simulations of large molecular systems with fast turnaround times. This service employs classical physics-based force fields to model molecular behavior, making it particularly valuable for drug discovery, materials science, and biochemical studies.
Introduction to Molecular Mechanics Calculation
Molecular mechanics (MM) calculations use classical Newtonian mechanics to describe molecular systems through potential energy functions (called force fields). These methods approximate molecular interactions using bond stretching, angular bending, torsional rotations, and non-bonded interactions (van der Waals and electrostatic forces). Molecular mechanics can simulate larger systems (thousands to millions of atoms) over longer time scales. The method has proven to be particularly effective for protein-ligand interactions, conformational analysis, and molecular dynamics simulations.
