Web1 jul. 2014 · An example is the attraction between a -COO- ion of lysine and an -NH+ 3 ion of aspartic acid. Increasing the pH by adding a base converts the -NH+ 3 ion to a neutral -NH2 group. Decreasing the pH by adding an acid converts the –COO- ion to a neutral -COOH group. In each case the ionic attraction disappears, and the protein shape unfolds. WebEnzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH. This is graphically illustrated in …
