Effects of urea, tetramethyl urea, and trimethylamine N-oxide on aqueous solution structure and solvation of protein backbones: a molecular dynamics simulation study.

Haiyan Wei et al.

The journal of physical chemistry. B, 114(1), 557-568 (2009-11-26)

The effects of urea, tetramethyl urea (TMU), and trimethylamine N-oxide (TMAO) on the structure and dynamics of aqueous solutions are studied using molecular dynamics simulations. It was found that urea has little effects on the water-water hydrogen-bond length and angle

Is a methyl group always hydrophobic? Hydrophilicity of trimethylamine-N-oxide, tetramethyl urea and tetramethylammonium ion.

Yoshikata Koga et al.

The journal of physical chemistry. B, 115(12), 2995-3002 (2011-03-10)

We have developed what we call the 1-propanol(1P) probing methodology. By using it, we determined the relative hydrophobicity/hydrophilicity indices of 2-butoxyethanol, a typical hydrophobe; urea, a typical hydrophile; and trimethylamine-N-oxide, an amphiphile. By comparing these indices with those for other

THz spectra and dynamics of aqueous solutions studied by the ultrafast optical Kerr effect.

Kamila Mazur et al.

The journal of physical chemistry. B, 115(11), 2563-2573 (2011-03-02)

The nature and extent of the effects that hydrophilic and hydrophobic solutes have on the dynamics of water molecules continues to be an area of intense experimental and theoretical investigation. In this work, we use the ultrafast optical Kerr effect
