What is the pH for pepsin?

Pepsin is a type of protease that works mainly in the stomach. As a result, its optimum pH is around 2. The high acidity is provided by the hydrochloric acid in the stomach.


What is the optimum pH of peptidase?

Most arginases have an alkaline pH optimum, with maximal velocities observed in the range of pH 9.0-9.5. For the rat liver enzyme, plots of logVmax versus pH provide a pK value of ∼7.8-8.0, while pK values of 7.8 and 7.9 have been reported for the human liver and mouse liver enzymes.


During digestion the pH in the stomach is 2 What does this indicate about the optimum pH of pepsin?

Pepsin is therefore acidic since the pH in the stomach is 2

At what pH would the enzyme be most effective?

It depends on what type of Enzyme. Enzymes have different optimum pH depending on the environment they work in, for example and enzyme in the stomach of a human would have a pH of about 2 but an enzyme in human saliva has an optimum pH of 5.6.


Optimum pH level for enzymes?

It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.


What type of enviorment does pepsin work best in?

The optimum pH of pepsin is pH2. Pepsin is found in the stomach and it is protease enzyme that digest protein into smaller molecule. The stomach is suitable place for it because it is acidic , so it's activity increases in the acidic environment.
