The origins of the elevated electronegative
LDL (LDL(-)) levels in the plasma of atherosclerotic patients are not completely understood.
The two carbon atoms attached to hydroxyl group in the resorcinol ring [C(1) and C(2)] resonated at 162.12 ppm and 160.95 ppm downfield, respectively due to the effect of the attached electronegative
element coupled with the fact that both carbons are [sp.sup.2] carbon.
Low-density lipoprotein (LDL) and especially its modifications, such as small dense, oxidized, desialylated, or electronegative
LDL, play the key role in atherogenesis, and their levels positively correlate with the disease progression [77-79].

gases," IEEE Transactions on Electrical Insulation, vol.
Carbide are being defined as the compound composed of carbon and a less electronegative
element, so metal carbides are composed of metal and carbon atoms bonded together.
The initial catalytic step consists of a nucleophilic attack ([S.sub.N]2 type) of the partial electronegative
oxygen atom of the hydroxyl group of the Ser at the (electropositive) silicon atom of the silicic acid molecule.
"It replaces hydrogen because of its small size but it also brings with it electronic effects since fluorine is an electronegative
element--it just pulls electrons from its surroundings."
Since these atoms are increasingly electronegative
towards the upper right of the periodic table, they may share a lack of ability to enter into condensation reactions that involve the delivery of a hydrogen atom.
(11-13) The hydroxyl group of HEA not only reacts with PIH to form covalently crosslinking networks, but also engages in intramolecular and/or intermolecular hydrogen bonding with carbonyl, ether, or other electronegative
acceptor functionality in the polymeric states.
The introduction of a fluorine atom into a molecule is known to impart unique properties due to its highly electronegative
nature and small size.
When an area of the brain is in use, it shifts to an electronegative
Sodium fluoride is a toxic, highly electronegative
compound that floods public drinking water, lurks in toothpaste, produce, and pharmaceuticals.
