Effect of pH on glycogen degradation by salivary α-amylase.

<p>Saliva was collected from a normal donor and incubated with glycogen at pH 4–7. The percent of degradation of glycogen at pH 7 is shown on the y axis. Average of four experiments. Degradation at pH 4 was significantly different than that at pH 6 and 7 (p<0.05, Mann-Whitney test).
