Facts about pepsin enzyme

Pepsin is a key ingredient for a healthy digestive process.

Its effectiveness in breaking down food in the stomach relies on a precise system of environmental controls preserving optimal pH levels.

Pepsin breaks down proteins into polypeptides inside the stomach. These polypeptides will break down further into amino acids, dipeptides, and tripeptides inside the small intestine.

Commercial pepsin is extracted from the glandular layer of hog stomachs.

 

Pepsin reaction mechanism

Pepsin is secreted in an inactive form (pepsinogen) in the digestive system

The inactive form, pepsinogen, needs a low pH environment in order to convert to pepsin.

Once pepsinogen reaches the stomach, where hydrochloric acid keeps the pH in the 1 to 3 range, it not only becomes pepsin but also triggers the formation of more pepsin.

 

Applications

Pepsin is used to modify and provide whipping qualities soy protein and gelatin

Pepsin can be applied to modify vegetable proteins which are used in the preparation of nondairy snack items.

It is used in the conversion of precooked cereals into instant hot cereals

Pepsin used to prepare animal and vegetable protein hydrolysates.

Pepsin is used in the leather industry to remove hair and residual tissue from hides.

Pepsin is used in the recovery of silver from discarded photographic films.

Pepsin is commonly used in the preparation of F(ab')2 fragments from antibodies.
