Researchers at Leipzig University have developed a new process for reversing the polarity of chemical compounds, also known as umpolung, for the precise synthesis of pharmaceuticals. "This ...

This is what causes atoms to bond and what holds a molecule together. Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one ...

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

When a charged object such as a rubber balloon is brought close to a fine stream of a polar liquid, the stream is attracted toward the electrical charge. If the same charged object is brought close to ...

Frizzled (Fz)/planar cell polarity (PCP) signalling is a conserved mechanism regulating the polarity of cells along the axes of a tissue. Fz/PCP regulates a diverse array of processes including ...
