Epithelial polarity is characterized by cell-cell junctions found near the apical-lateral domain (non-adhesive surface), and a basal lamina (adhesive surface) opposite the apical surface.

if the bond between the bonded atoms is polar, the molecule is said to be polar. the boiling point of a molecule is directly proportional to its polarity. the greater the polarity, the greater the boiling point. q-14: which of the following is the polar molecule? a) carbon dioxide b)...
Polarity is also determined by the shape of a molecule. Molecules that are symmetrical tend to be nonpolar. Molecules that are asymmetrical tend to be polar. Polarity is like a game of tug-o-war. If there is an equal "pull" on the central atom from all sides, then the molecule is non...
Conversely, if the moment is known, the inclination of the electric doublet to the optic axis can be found. For example, in the case of the simple dipole molecule HCl, we may assume the optic axis to be parallel to the doublet.

a radical and a substrate is given by log k = log k3,T + rxa + ß where log k3, T is the (measured) chain transfer constant for reaction of the radical with toluene, a is the Harnmett para sigma constant (determined in classical fashion) for the substituent on the carbon atom ...
Arrows indicate the activation or modulation of a molecule or promotion of molecular interactions. Dotted arrows, hypothetical pathways. RhoA activated by PDZ-RhoGEF might lead to not only ROCK activation but also DAAM1 activation forming a positive feedback loop. DAAM1 might independently regulate ...
the electron density clouds intersect with each other. This is most pronounced in a covalent bond, in which electrons are shared equally. When a molecule is polar, however, the electrons tend towards one of the atoms of the bond. The exact image of the electron density clouds for these bond...
Under a Creative Commons license open accessHighlights Summary Fatty acids have long been considered essential to brain development; however, the involvement of their synthesis in nervous system formation is unclear. We generate mice with knockout of GPSN2, an enzyme for synthesis of very-long-chain...
