Lysine low ph

WebAt 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). The charge on the amino acid side chain depends on the pK of the AA (Table 1) and on the pH of the solution.
