Charged amine
In chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR4] , R being an alkyl group or an aryl group. Unlike the ammonium ion (NH+4) and the primary, secondary, or tertiary ammonium cations, the quaternary ammonium cations are permanently charged, independent of the pH of their solution. Quaternary ammonium salts or quatern… WebMatch the amino acid and its side chain's functional group. alanine, valine, leucine, lsoleucine, A. aromatic (double-single bond conjugated system) ring (s) arginine, lysine, histidine B. thiol-SH asparagines, glutamine C. a positively charged amine, guanidinium or imidazole ring aspartic acid, glutamic acid D. thioether -CH_2-S-CH_3 cysteine ...
