Evidence relating to the structure and properties of swine pepsinogen and pepsin has been reviewed and used to suggest a tentative two dimensional picture of the skeleton of these two proteins. When pepsinogen, a folded single peptide chain, is converted to pepsin, there is a profound change in the physical and chemical properties of the protein. In an as yet unknown manner, except that it is initiated by a peptic cleavage of the protein chain, a single enzymic site is formed. This site is made up, quite probably, of the secondary carboxyl group of glutamic acid or of aspartic acid and a tyrosine phenol group in close proximity so that they can form hydrogen or hydrophobic bonds with the substrate in some unique manner that permits hydrolysis to occur at an accelerated rate.

What produces HCI and pepsinogen?
Hydrochloric acid (HCl) is produced by parietal cells in the stomach, while pepsinogen is produced by chief cells in the stomach. Together, HCl and pepsinogen play important roles in the chemical digestion of food in the stomach.
Does hydrochloric acid activate pepsinogen in the stomach?
Yes, hydrochloric acid activates pepsinogen in the stomach to convert it into its active form, pepsin, which helps in the digestion of proteins.
How is pepsinogen activated in the stomach to become the active enzyme pepsin?
Pepsinogen is activated in the stomach by the acidic environment, which triggers a change in its structure to become the active enzyme pepsin.
What is the source of pepsin?
Pepsin is an enzyme which is secreted by Zymogen cells of the stomach. First it is secreted in an inactive form called Pepsinogen. After that Hydrochloric acid (HCl) activates it into pepsin. FUNCTION:Its function is to hydrolyse the proteins to yield peptide.
What is the name of the inactive form of a protein splitting enzyme in the stomach?
The inactive form of a protein splitting enzyme in the stomach is called pepsinogen. It gets converted to its active form, pepsin, when exposed to the acidic environment of the stomach.
What is the relation between pepsinogen and hydrochloric acid?
Pepsinogen is an inactive precursor of the enzyme pepsin, which is responsible for breaking down proteins in the stomach. Hydrochloric acid activates pepsinogen, converting it into pepsin. The presence of hydrochloric acid in the stomach helps to create an acidic environment that allows pepsin to function optimally.
What are the function of the pepsinogen in gastric juice?
Gastric juice, as known is an acidic juice present in the stomach. Pepsinogen in gastric juice conveys it to convert the pieces of food into a thick paste which then continues on. ^_^
What produces HCI and pepsinogen?
Hydrochloric acid (HCl) is produced by parietal cells in the stomach, while pepsinogen is produced by chief cells in the stomach. Together, HCl and pepsinogen play important roles in the chemical digestion of food in the stomach.
Does hydrochloric acid activate pepsinogen in the stomach?
Yes, hydrochloric acid activates pepsinogen in the stomach to convert it into its active form, pepsin, which helps in the digestion of proteins.
How is pepsinogen activated in the stomach to become the active enzyme pepsin?
Pepsinogen is activated in the stomach by the acidic environment, which triggers a change in its structure to become the active enzyme pepsin.
Name 2 secretions the stomach makes and what do they do?
pepsinogen mucus

What is the name of the inactive form of a protein splitting enzyme in the stomach?
The inactive form of a protein splitting enzyme in the stomach is called pepsinogen. It gets converted to its active form, pepsin, when exposed to the acidic environment of the stomach.
Pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells?
it is secreted by stomach glands as an inactive proenzyme, pepsinogen, which is converted to pepsin by the cleavage of acid-labile linkages in the acidic (low pH) environment of the stomach.
What is the difference between pepsin and pepsinogen?
Pepsin is a powerful protein digesting enzyme which is far too dangerous in its active form so it is released in an inactive pepsinogen form by the cell and activated only in the digestive tract where it is required to be active.
What prevents pepsin from destroying the cell walls in the stomach?
Pepsin is secreted as pepsinogen. Pepsinogen cannot eat the walls of the stomach. Now, pepsin is formed when pepsinogen binds to the hydrochloric acid (HCl) in the stomach. Once they are binded pepsin is formed. The second reason on why the stomach doesn't eat it's self is because of the alkaline mucus that suround the walls of the stomach.
Gastrin secretes what?
pepsinogen (a precursor of pepsin) which helps humans digest, when activated by HCL.
