Low pH(HCl) amylase incubated at 100c
investigate the relationship between reaction temperature and the effectiveness of the Enzyme amalayse on starch
The optimum pH is neutral, 7.
The optimum pH of salivary amylase is 6.8 (slightly acidic).
In the stomach, the pH could be as low as 2. Pepsin is an enzyme that breaks up protein molecules. It needs to have an optimum pH close to that. In the mouth, amylase occurs. pH in the mouth is often about 7. Optimum pH for amylase needs to be close to that.
The activity of amylase decreases drastcially due to the very low pH this is one of the reasons more amylase is added by the pacreas.
optimum pH of amylase from sweet potato is about 6.0
Low pH(HCl) amylase incubated at 100c
Salivary amylase works well around pH 7 (inside the mouth), but inside the stomach are gastric juices which contain HCl. Since the HCl drops the pH of the solution significantly, it denatures the amylase so that it will no longer function as it normally would, breaking down starch and glycogen.

The optimum pH of a bacterial amylase depends on the species of bacterium. One review of different species found optima ranging from pH 4 to 11.To take one example, the α-amylase from Bacillus amyloliquefaciens (BAA) has an optimum pH of 6.Bacterial amylases are important in a number of industrial processes.
pH of about 7
About 7.4 pH.
The optimum pH is neutral, 7.
The optimum pH of salivary amylase is 6.8 (slightly acidic).
Because that's the average (more or less) pH of the mouth and of the small intestine. If the optimum pH of amylase is not met, the enzyme will denature.
Because, Amylase is the main emzyne in saliva that converts starch into sugar and the average pH of saliva is 7.
