Pi value of casein
WebJul 9, 2016 · Casein’s isolelectric point is 4.6. It has a negative. The isoelectric point (pI) is the pH of a solution at which the net primary charge of a protein becomes zero. At a solution pH that is above the pI the surface of the protein is predominantly negatively charged and therefore like-charged molecules will exhibit repulsive forces. WebOct 2, 2012 · These pI values measured with the developed method were close to the theoretical and experimental literature values. The method is sensitive and requires a …
