Polarity

Definition

noun

(1) The presence of or having distinct and opposite poles

(2) The condition of having contrasting properties or direction

(3) (chemistry) The tendency of forming distinctive opposing charges based on the orientation of chemical bonds and spatial structure of the molecule


Supplement

(Chemistry) Polarity confers molecules and compounds distinctive features in terms of structure and chemical interaction with other molecules. Water is a polar molecule. Polarity enables water to interact with various compounds.

(Biology) Polarity is also an essential and common feature in organisms, particularly at the cell level. Examples of polarity manifested in a cell or group of cells are as follows:

holographic origin of life

... will react arbitrarily and will become more complex. Some pathways will be more favourable (especially due to repeatabilty, adhesive properties, polarity etc) and will prevail in the long term. If the chemicals of the system is used as a reference frame, what will happen? To its own viewpoint, ...

Re: Are carbohydrates hydrophobic?

... carbohydrates is that starches, polymers of glucose, are not soluble in water and serve as energy-storing molecules. (“Carbohydrates” (2)). The polarity of water makes it a “universal solvent”. Its components have a slight electrical charge that makes possible the dissolution of ions. Many authors ...

plants' intelligence (neurosensing)

... this today. It is very interesting. For what purpose did it evolve? I figure, flow of electrons through air or surfaces can disturb plant cell's polarity (ion gradient), so the plant has some information about electrical particles in its environment. Okay, this is useful. What about your ideas? ...
