anion (ăn`ī'ən), atom or group of atoms carrying a negative charge. The charge results because there are more electrons than protons in the anion. Anions can be formed from nonmetals by reduction (see oxidation and reduction oxidation and reduction, complementary chemical reactions characterized by the loss or gain, respectively, of one or more electrons by an atom or molecule. Originally the term oxidation

Properties ..... Click the link for more information. ) or polar compounds by ionization. Anionic species include Cl−, SO4−−, and CH3COO−. Highly colored intermediates in organic reactions are often radical anions (anions containing an unpaired electron).

The charge results because there are more protons than electrons in the cation.

Anions in a liquid subjected to an electric field migrate toward the positive electrode (anode). Examples include hydroxyl (−OH−; see hydroxide), carbonate (−CO32−), and phosphate (−PO43−). See also ion; compare cation. anion a negatively charged ion; an ion that is attracted to the anode during electrolysis anion [′a‚nī·ən] (chemistry) An ion that is negatively charged.

No references found | Both organic anions and xenobiotics in the blood use the same organic anion transporters (OATs) for entry into proximal tubule cells and they then exit these cells through ATP dependent ABCC2 (MRP2) and ABCC4 (MRP4), cassette transporters located at the luminal membrane of the cells (Sekine et al. we have great separation for the following ionic and organic residues (Figure 3): * Anions by AS22 separate fluoride, formate, acetate, MSA, chloride, nitrite, bromide, nitrate, phosphate, sulfate, succinic, malic, maliec, glutaric and adipic acids. Some researchers had suggested that anions, which have one or more extra electrons in comparison with a neutral molecule, might be too fragile to exist for long periods. |
