| 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) |
|---|
| anionic detergents | Detergent's, such as soaps (alkali metal salts of long-chain fatty acids), that carry a negative electric charge on a lipid-like molecule and exert a limited antibacterial effect. (05 Mar 2000) |
|---|---|
| detergents | Purifying or cleansing agents, usually salts of long-chain aliphatic bases or acids, that exert cleansing (oil-dissolving) and antimicrobial effects through a surface action that depends on possessing both hydrophilic and hydrophobic properties. (12 Dec 1998) |
| cationic | Referring to positively charged ions and their properties. (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) |
| eosinophil cationic protein | <protein> Arginine rich protein (21 kD) in granules of eosinophils, that damages schistosomula in vitro. Not the same as the MBP (major basic protein) of the granules. (18 Nov 1997) |
