Webfunctional groups: arginine, histidine, and lysine. Aspartate and glutamate are acidic amino acids. Their counterparts asparagine and glutamine are amides. Acid–base properties. All of the amino acids have an acidic group (COOH) and a basic group (NH2) attached to the α carbon. Two of the amino acids have very acidic side chains: Weband de-ionized water was added every 2 days during culti-vation. One week after sowing, the plant numbers were reduced to two per pot. At 2 weeks after sowing, the water in the container was replaced with 2.2 L of 10 lmol L)1 CdCl 2 (Cd treatment) or de-ionized water (control) to maintain the surfaces of the water and soil at the same height.
Special cases: Histidine, proline, glycine, cysteine
WebEvery free amino acid has at least two ionizable functional groups, the amino group and the carboxylic acid group. Some amino acids have ionizable side chains, like aspartate, glutamate, lysine, arginine, histidine, tyrosine, and cysteine. Each ionizable group has a characteristic pKa.
