Energy Analysis of Biofilm System

The binding free energy refers to the interaction that exists between the ligand and the receptor. Nonbonding interactions {weak interactions, low energy} exist in most systems and are mainly composed of three terms: van der Waals interactions, electrostatic interactions, and hydrogen bonding interactions, all of which can be calculated using the force field method. The covalent interaction (strong interaction, high energy) only exists in very individual systems, and its essence is the breaking of old chemical bonds and the generation of new chemical bonds. In actual drug small molecule (ligand) and protein (receptor) complex systems, generally only non-bonded interactions exist. Using the experimental temperature T and the binding constant K, the binding free energy can be roughly estimated. CD BioSciences use computer-aided methods to provide energy analysis service of biofilm system to help customers complete biofilm related research.

Our Services

CD BioSciences provides one-stop energy analysis service of biofilm system. We offer a variety of methods and software to choose from to meet your research needs.

Specific Energy Analysis Approaches We Offer

The calculation methods of free energy provided by CD BioSciences can be mainly divided into three categories:

  • Free Energy Perturbation (FEN) and Thermodynamic Integration (Thermodynamic Integration. TI) Methods
    This type of method is relatively strict in principle, and the calculation results are relatively accurate. However, it requires a long period of data collection, has strict restrictions on the calculation system, and can only be suitable for relatively simple situations.
  • Calculation Method Based on Empirical Equation
    This type of method decomposes the binding free energy into different interaction energy terms, and uses a set of training sets and uses statistical methods to obtain empirical formulas for free energy calculations. This kind of method is simple in sampling and small in calculation, and is widely used in drug design.
  • LIE Method and MM/PBSA Method
    The LIE method and the MM/PBSA method are the free energy prediction methods based on molecular dynamics sampling developed in recent years, mainly including the LIE method and the MM/PBSA method.
