What type of environment does pepsin work best?

What is the optimum pH of pepsin?
Where does pepsin function best?
The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7), and pepsin is no longer effective.
Why does pepsin need an acidic environment?
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.
What is the main function of pepsin?
Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach.
Is pepsin acidic or basic?
Pepsin, the first animal enzyme discovered (Florkin, 1957), is an acidic protease that catalyzes the breakdown of proteins into peptides in the stomach, while it does not digest the body’s own proteins.
How can we detect the presence of pepsin?
The diagnostic test, Peptest (RD Biomed Ltd, Cottingham, UK), detects pepsin in expectorated saliva and is established as a simple, noninvasive measure of reflux of gastric contents.
What foods activate pepsin?
Pepsin only gets activated when exposed to acidic surroundings (most active at pH less than 4). So when one eats or drinks a very acidic substance (e.g. lemon, vinegar, wine, tomato, sugary soda or bottled iced tea) what you eat starts eating you.
