Molecular Modeling

Molecular dynamics (MD) simulations are a powerful computational tool for understanding structure–dynamics–function relationships at the atomic level; however, reaching long timescales, especially in large biomolecular systems, entails substantial computational cost. For this reason, numerous “acceleration algorithms” have been developed, ranging from the numerical integration of the equations of motion—forming the foundation of classical MD—to the optimization of force calcu

When investigating the behavior of microscopic systems using in silico methods, it is critically important to define the physical conditions under which the system evolves. While energy is conserved in an isolated system (microcanonical ensemble), real experimental conditions are typically open to heat and work exchange with the surrounding environment.

Bilgisayar tabanlı moleküler dinamik (MD) simülasyonları, klasik hareket kurallarını kullanarak biyolojik sistemlerde yer alan atom ve moleküllerin zaman içerisindeki hareketlerini inceler. 1950'lerden beri moleküler simülasyonlar; yoğun madde sistemlerindeki sorunları çözmek çözmek amacıyla kullanılmaktadır.

In molecular modeling, the factors that determine the energy of a system are not limited to bonded interactions such as bonds, angles, and torsions. Even when atoms are not directly connected through covalent bonds, they can still influence each other via non-bonded interactions. These interactions form the basis of many physical and biological processes, including molecular folding, stability, binding affinity, and phase behavior.

Moleküler modelleme, atomlar arası etkileşimleri sayısal olarak tanımlayarak doğadaki fiziksel süreçleri bilgisayar ortamında canlandırmayı amaçlamaktadır. Bu sürecin temel yapı taşlarından biri olan kuvvet alanları (force fields), atomların birbirleriyle nasıl etkileştiğini belirleyen matematiksel fonksiyonlar ve parametrik sabitler bütünüdür. Kuvvet alanları sayesinde moleküllerin geometrisi optimize edilir.
