polar compound


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

po·lar com·pound

a compound in which the electric charge is not symmetrically distributed, so that there is a separation of charge or partial charge and formation of definite positive and negative poles, for example, H2O. See also inorganic compound.

polar compound

A molecule with distinct electrical charges in different regions, i.e., a positive charge in one region and a negative charge in another.

(14) The limitation of liquid C[O.sub.2] is exactly the opposite to that of water, in that polar compounds are not soluble in carbon dioxide.
However, when the same pot of oil is repeatedly reheated, the oils begin to degrade, releasing substances known as polymers and polar compounds that can become absorbed by food.
The meter is designed to address health issues for fast and pre-prepared foods by testing the quality of the oil as it ages during frying and the polar compounds found in that oil.
It thoroughly cleans frying oil by physically removing food particles during filtration, and removes--by adsorption oil soluble substances like Free Fatty Acids, colour bodies, and other polar compounds during contact.
MOSFET sensors are sensitive to a broad range of hydrogen-containing or polar compounds such as hydrogen, amines, aldehydes, esters, ketones, aromates and alcohols.
Oil was analyzed for free fatty acid (FFA) content, color, food oil sensory values and total polar compounds (TPC).
Because of the multiphase nature of ionomers, consisting of ionic domains dispersed within a non-polar matrix, plasticization of ionomers has been investigated using both non-polar and polar compounds. Several studies (2-7) have shown that nonpolar plasticizers can plasticize both the ionic phase and the nonionic matrix polymer, while some polar plasticizers are able to selectively plasticize the ionic regions as a result of their preferential segregation into the polar ionic multiplets.
