WebThe degree of ionization (pKa) of a drug is a unique physicochemical property that controls its ionization state when in solution. If the drug's p Ka is the same as the pH of the solution it is dissolved in, then 50% of the drug exists ionized and 50% exists nonionized. As the pH of the solution changes, the state of ionization changes as well. WebLysine plays several roles in humans, most importantly proteinogenesis, but also in the crosslinking of collagen polypeptides, uptake of essential mineral nutrients, and in the production of carnitine, which is key in fatty acid metabolism. Lysine is also often involved in histone modifications, and thus, impacts the epigenome.
