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 optimum pH of lactase is pH = 6.5.

Pepsin is an enzyme that catalyzes the breakdown of proteins int peptides. Its optimum pH range is between 1 to 4.
optimum pH of amylase from sweet potato is about 6.0
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.
The optimum pH of salivary amylase is 6.8 (slightly acidic).
Amylase has an optimal pH range of 6.7 - 7.0 and an optimal temperature of around 37 degrees Celsius or 98.6 degrees Fahrenheit. This is what would be expected of an enzyme that needs to be in its most active form in the saliva of the mouth.
Yes. Some plants are found to have amylase as well, such as those plants with high levels of starch, and they are the same types of amylase.
identify two pH values at which salivary amylase activity stop?
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
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.
Ptyalin is an alpha-amylase. It is the alpha-amylase found in saliva
In the mouth, salivary amylase works to break down cooked starch into maltose. The duodenum (first part of the small intestine), pancreatic amylase works to do the same. Amylase only works in these places because they provide the optimum pH conditions for amylase to work (range from pH 6 - 8).
Alpha bonds are hydrolised by alpha amylase. The alpha amylase is the sole form of amylase found in all mammals.
No, absolutely not, it will not 'work' in alkaline (basic) solution. Salivary amylase (ptyalin) inactivates rapidly outside of its optimum pH 5.6-6.9
