Course objectives
The course is focused on basics of interatomic and intermolecular interactions in biopolymers. It is aimed on description of fundamental forces in biomolecules, influence of solvent, and molecular modeling approach.

The main objective of the course is to provide the students with the ability to
- describe and explain fundamental interactions in biomolecules
- apply the obtained knowledge to practical problems
- understand current trends
Syllabus
  • 1. electrostatic interactions in vacuum: Coulomb law, superposition principle, interactions of charges, dipoles, rotating dipoles, and induced dipoles, van der Waals interaction
  • 2. electrostatic interactions in aqueous solutions: Poisson-Boltzmann equation, Debye-Hückel theory, Debye screening length, Gouy-Chapman theory, fluctuating charges
  • 3. interactions of big uncharged particles: Hamaker constant, Derjaguin approximation, solution for particles with different geometries
  • 4. entropic interactions: directional entropic forces, ideal chain and its deformations, membrane fluctuations
  • 5. depletion interaction, hydrophobic interaction, DLVO theory, hydrogen bond, salt bridge, π-interaction
  • 6. polymers in aqueous solutions: Flory-Huggins theory, polymer mixtures
  • 7. protein folding: native contacts, funneling, helix-coil transition, swelling, crowding
  • 8. biopolymer models: ab initio, all-atom description, molecular mechanics, coarse-grained simulations
  • 9. radial distribution function, matter arrangement, structure factor
