WebOct 4, 2024 · What is the net charge of lysine at pH of 14? +2 The pH Profile of Lysine. Lysine contains a carboxylic acid group, the a-amino group, and a second amino group attached to the side chain. In a very acidic solution, pH=1, all of these groups are protonated. The net charge on the lysine is +2 (State A). The most common role for lysine is proteinogenesis. Lysine frequently plays an important role in protein structure. Since its side chain contains a positively charged group on one end and a long hydrophobic carbon tail close to the backbone, lysine is considered somewhat amphipathic. For this reason, lysine can be … See more Lysine (symbol Lys or K) is an α-amino acid that is a precursor to many proteins.
