Web26 feb. 2024 · The ionization state of titratable residues affects the function, stability, structure and solubility of protein . Ionizable residues also play a key role in protein folding ( 4 , 5 ). pH dependence of protein stability and conformations can be explained in many cases by perturbed pKa values of ionizable residues ( 6–8 ). Lysine was first isolated by the German biological chemist Ferdinand Heinrich Edmund Drechsel in 1889 from the protein casein in milk. He named it "lysin". In 1902, the German chemists Emil Fischer and Fritz Weigert determined lysine's chemical structure by synthesizing it.
