Digestive enzymes help to break down food in its simplest form. Pepsin is a digestive enzyme which leads to the degradation of proteins in the stomach. It is produced as pepsinogen and converted to active pepsin in the stomach by the removal of several amino acids.
<h3>What is pepsin?</h3>
Pepsin is a digestive enzyme which is present mainly in the gastric juice in stomach and helps to breakdown protein into peptides.
This pepsin is present in the stomach in the form of inactive pepsinogen. This pepsinogen gets active in the stomach by the action of hydrochloric acid.
Pepsinogen gets active and forms pepsin.
Thus, it can be concluded that the digestive enzyme pepsin degrades protein in stomach and is synthesized as pepsinogen and gets converted into active pepsin in stomach by removal of several amino acids.
