What is the optimal pH for pepsin?
Likewise, people ask, why is the optimum pH of pepsin 2?
The reason pepsin functions best at pH 2 is because the carboxylic acid group on the amino acid in the enzyme’s active site must be in its protonated state, meaning bound to a hydrogen atom. At low pH the carboxylic acid group is protonated, which allows it to catalyze the chemical reaction of breaking chemical bonds.
Also Know, what is the optimal pH for salivary amylase? The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denaturated. The enzyme salivary amylase is most active at pH 6.8.
Beside this, what is the optimal pH for this enzyme?
Most enzymes‘ optimum pH is neutral or close to neutral, like amylase found in saliva, which has an optimal pH = 6.8. Some enzymes prefer a more drastic pH, like pepsin, which can have an optimum pH of 1.7 to 2. Sometimes enzyme pH optima depends on where the enzyme is found.
What is the optimal pH for lipase?
The optimum pH of gastric lipase is 3 – 6, meaning that gastric lipase does not work at its optimum pH in the stomach (although pepsin – a protease that has an optimum pH of 1.5 to 2 is closer to its optimum pH).
