[L. polus, end of axis] Having parts or areas with opposed or contrasting properties, such as positive and negative charges, head and tail.

In chemistry, referring to a compound in which electrons are not shared equally in the chemical bond, resulting in partial electrical charges. The best example is water, H2O, where the oxygen atom &am [..]

having to do with the North and South poles. Polar bears live near the North Pole

adj. Pertaining to the poles of a sphere, especially of the earth.

Expressed in terms of distance (from a point called the pole) and angle (with a ray as the initial side of the angle).

Any molecule that has a partial positive charge at one side and a partial negative charge at the other. Polar molecules react with water (they are hydrophilic). The glycerol and phosphate heads of the [..]

Referring to a molecule or structure with a net electric charge or asymmetric distribution of positive and negative charges. Polar molecules are usually soluble in water.
