Euler-Poincare Dynamics of Ideal MIcropolar Complex Fluids

Lagrangian reduction by stages is used to derive the Euler-Poincare equations for the coupled motion and micromotion of ideal micropolar complex fluids. The order parameters for micropolar complex fluids are material variables that may be regarded either as geometrical objects in a vector space, or as taking values in coset spaces of Lie symmetry groups. Examples include liquid crystals, superfluids, Yang-Mills magnetofluids and spin-glasses. A Lie-Poisson Hamiltonian formulation for the dynamics of ideal micropolar complex fluids is obtained by Legendre transforming the Euler-Poincare formulation. These dynamics are also derived by using the Clebsch approach.

The Osmophobic Effect: A Fundamental Thermodynamic Force in Protein Folding

The natural selection of small organic molecules (osmolytes) that protect cellular proteins against denaturing stresses is characteristic of plants and animals that have adapted to environmental extremes. The key property of the osmolytes is that even in the presence of the denaturing stress they selectively destabilize the denatured states of proteins, thereby populating the native state. We have proposed that destabilization of the denatured state arises from the unfavorable interaction of the osmolyte with the peptide backbone that is exposed on denaturation. This unfavorable interaction between peptide backbone and osmolyte is known as the osmophobic effect, and its magnitude is dependent on the nature of the osmolyte. The osmophobic effect is attenuated by favorable interactions between the protein's side chains and osmolyte, giving a range of efficacies in protein stabilization among the naturally occurring osmolytes. The proposal of the osmophobic effect and its attenuation by favorable side chain-osmolyte interactions is a chemical explanation of the phenomenon of osmolyte-mediated protein stabilization, and is distinct from physical explanations of the phenomenon that have been offered that are derived from the solution properties of the osmolytes. Hydrogen bonding, electrostatic, van der Waals, and hydrophobic interactions, have long been cited as the fundamental thermodynamic forces involved in protein folding. Osmolytes have little effect on these fundamental thermodynamic forces, so the rules for protein folding in the presence of osmolyte is much the same as in its absence. In organisms containing osmolytes, the osmophobic force has a special place in nature, affecting a part of the protein (peptide backbone) in a way that is complementary to the hydrophobic, hydrogen bonding, electrostatic, and van der Waals forces. In its setting, the osmophobic effect is as fundamental and important to protein folding as any of the traditional thermodynamic forces in protein folding.
