| cation-anion difference | <biochemistry> The difference between the sum of the measured cations and anions in the plasma or serum calculated as follows: (Na + K) -(Cl + HCO3) = < 20 mmol/l. Elevated values may occur in diabetic or lactic acidosis; normal or low values occur in bicarbonate-losing metabolic acidoses. Synonym: cation-anion difference. (05 Mar 2000) |

| cationic | Referring to positively charged ions and their properties. (05 Mar 2000) |
| cationic detergents | Detergent's, such as the amine salts or quaternary ammonium or pyridinium compounds of long-chain fatty acids, that have positively charged groups attached to the larger hydrophobic portions. (05 Mar 2000) |
| cationic protein | <biochemistry> Proteins of azurophil granules of neutrophils, rich in arginine. A chymotrypsin like protease found in azurophil granules is also very cationic as is cathepsin G and neutrophil elastase. Eosinophil cationic protein (21 kD) is particularly important because it damages schistosomula in vitro. (16 Mar 1998) |
| cationised ferritin | <chemical> Ferritin, treated with dimethyl propanediamine and used to show, in the electron microscope, the distribution of negative charge on the surface of a cell. The amount of cationic ferritin binding is very approximately related to the surface charge. (16 Mar 1998) |
| cationogen | A substance that gives rise to positively charged ions. (05 Mar 2000) |
| cations | Postively charged atoms, radicals or groups of atoms which travel to the cathode or negative pole during electrolysis. (12 Dec 1998) |
| cations, divalent | Positively charged atoms, radicals or groups of atoms with a valence of plus 2, which travel to the cathode or negative pole during electrolysis. (12 Dec 1998) |
| cations, monovalent | Positively charged atoms, radicals or group of atoms with a valence of plus 1, which travel to the cathode or negative pole during electrolysis. (12 Dec 1998) |
| catkin | <plant biology> A spike in which the flowers are unisexual and without conspicuous perianth. (16 Mar 1998) |
