Polarity of molecules is one of the central concepts that is used for predicting or rationalizing a wide array of concepts in the undergraduate chemistry curriculum. These concepts include the physical properties of molecules at the freshman level, structure-reactivity relationships in organic and ...
On attempting to correlate the electrical double-refraction (Kerr effect) of gases and vapours which has been measured by Leiser, Hansen and Szivessy, with the optical anisotropy of the molecules determined from observations on light-scattering, it is found that electrically polar molecules generally...
in several keycellular processesincluding collective cell migration and maintenance of tissue architecture[9,10]. PCP, which is aligned perpendicular to the ABP plane, is composed of conservative core molecules, effector molecules, and signal regulators that comprise the fundamental polarity of PCP[11]...
a molecule may be polar or non-polar. a non-polar molecule has a structure of its atoms lined up in a way that the orbital electrons in the outer region cancel out the electronegativity. in general, pyramid-shaped and v-shaped molecules are said to be polar. whereas the linear molecules...

To demonstrate their technique, the researchers examined several simple molecules. In all cases, the results were closer than traditional KPFS to theoretical predictions. For example, they looked at the structurally identical molecules F12C18Hg3 and H12C18Hg3, showing for the first time that the ...
Assess the polarity of a molecule based on its bonding and structure Thus far, we have used two-dimensional Lewis structures to represent molecules. However, molecular structure is actually three-dimensional, and it is important to be able to describe molecular bonds in terms of their distances,...
In mesenchymal cell motility, several migration patterns have been observed, including directional, exploratory and stationary. Two key members of the Rho-family of GTPases, Rac and Rho, along with an adaptor protein called paxillin, have been particularly implicated in the formation of such migrati...
