Arginine is well designed to bind the phosphate anion, and is often … WebThe polar nature of amino acids requires derivatization prior to GC analysis. The goal of derivatization is to make an analyte more volatile, less reactive, and thus improve its chromatographic behavior. In the case of amino acids, derivatization replaces active hydrogens on OH, NH2, and SH polar functional groups with a nonpolar moiety. dr michael toomey

Difference Between Polar and Nonpolar Amino Acids

WebAmong the 20 common amino acids, five have a side chain which can be charged. At pH=7, two are negative charged: aspartic acid (Asp, D) and glutamic acid (Glu, E) ( acidic side chains), and three are positive charged: lysine (Lys, K), arginine (Arg, R) and histidine (His, H) ( basic side chains).
