Ionized form of lysine
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. Meer weergeven Lysine (symbol Lys or K) is an α-amino acid that is a precursor to many proteins. It contains an α-amino group (which is in the protonated −NH 3 form under biological conditions), an α-carboxylic acid group (which is in … Meer weergeven Two pathways have been identified in nature for the synthesis of lysine.

WebLysine, for example, could be represented by the following diagram. At physiological pH, lysine has a net positive charge. Thus, we have to increase the pH of the solution to remove positive charge in order to reach the isoelectric point.
