Hydrophobicity
As anyone who has looked at a petunia or a pansy can testify, plants generate flowers with characteristic numbers and patterns of organs. The floral organs are derived from a pool of stem cells called the floral meristem. In wild-type Arabidopsis thaliana flowers (shown at lower left) the meristem gives rise to four sepals that enclose the bud, four white petals, six pollen-bearing stamens and ...
متن کاملThe meaning of hydrophobicity.
K. P. Murphy et al. (1, 2, 3) recently proposed what would appear to be a profound change in our way of thinking about hydrophobic interactions. On the basis of their elegant and careful experiments on small molecules (4) and on proteins (5), they propose that "for globular proteins hydrophobic interactions lead to destabilization" (1) and that "the hydration effect of nonpolar solutes stabiliz...
متن کاملHydrophobicity--getting into hot water.
In his famous 1959 review, Walter Kauzmann clarified important features of the thermodynamic stabilities of proteins. The hydrophobic effect is recognised as an important contributor to the stability of proteins and an important determinant of their structural patterns. As generally understood, it depends on the unusual properties of cold water and its interactions with nonpolar solutes. Here w...

متن کاملMolecular origins of fluorocarbon hydrophobicity.
We have undertaken atomistic molecular simulations to systematically determine the structural contributions to the hydrophobicity of fluorinated solutes and surfaces compared to the corresponding hydrocarbon, yielding a unified explanation for these phenomena. We have transformed a short chain alkane, n-octane, to n-perfluorooctane in stages. The free-energy changes and the entropic components ...
