What is pepsionogen?

this is the proenzyme of pepsin , which is a protein digesting enzyme. pepsinogen is secreted by gastric mucosal cell


Why can pepsin not be produced in its active form?

Pepsin is initially secreted as an inactive precursor called pepsinogen to prevent auto-digestion of the cells that produce it. Once pepsinogen is released into the acidic environment of the stomach, it is activated by hydrochloric acid to form pepsin, which can then break down proteins. This activation process ensures that pepsin only becomes active when it is in the stomach and ready to perform its digestive function.


Is pepsin a polypeptide?

Pepsinogen is the proenzyme of pepsin. Pepsinogen is inactive, it is metabolized into the enzyme pepsin which break down proteins into small molecules.


What are precursor proteins?

Some proteins are made as its inactive form known as Zymogens (proenzyme). classical example are trpsinogen, chymotrypsinogen and even insulin as proinsulin. They have to undergo a chemical change to become active enzyme trypisn, chymotrypis or insulin.


Can you name 5 enzymes in the human body?

1) Amylase I and II are secreted, first by the salivary glands, and then by the pancreas. Amylase II, produced by the pancreas, is only slightly different chemically and continues the process started by the salivary amylase. 2) Pepsin is secreted as proenzyme pepsinogen by the chief cells of the stomach and activated by hydrogen in the stomach acid, also producing hydrochloric acid at the same time. 3) Trypsin is secreted from the pancreas as proenzyme trypsinogen. Trypsin acts on proteins and polypeptides to produce short-chain peptides. It also activates other pancreatic proteinases. 4) Chymotrypsin is secreted by the pancreas as proenzyme chymotrypsinogen. Chymotrypsin acts on proteins and polypeptides to produce short-chain peptides. 5) Carboxypeptidase is secreted by the pancreas as proenzyme procarboxypeptidase. Carboxypeptidase acts on proteins and polypeptides to produce short-chain peptides and amino acids. 6) Elastase is secreted by the pancreas as proenzyme proelastase. Elastase targets elastin to produce short-chain peptides. 7) Lipase is secreted by the pancreas -- but only if bile salts are present. Lipase targets triglycerides to produce fatty acids and monoglycerides. Lipase also seems to be activated by the presence of Vitamin C, glutathione, and cysteine. 8) Nuclease is secreted by the pancreas. Nuclease targets nucleic acids RNA and DNA to produce nitrogen bases and simple sugars. 9) Enterokinase is secreted by the mucosal cells of the small intestine and reaches the lumen through disintegration of shed epithelial cells. Enterokinase targets trypsinogen, a proenzyme, to produce trypsin. 10) Maltase, sucrase, and lactase are secreted by the mucosal cells of the small intestine and found in the membrane surface of microvilli. They respectively target the sugars maltose, sucrose, and lactose to produce monosaccharides. 11) Peptidase is secreted by the mucosal cells of the small intestine and found in membrane surfaces of the microvilli. Peptidase targets dipeptides and tripeptides to produce amino acids.

How does pepsinogen become active pepsin?

The proenzyme pepsinogen,on exposure to hydrochloric acid gets converted into active enzyme pepsin,the proteolytic enzyme of the stomach.Pepsin converts proteins into proteoses and peptones(peptides).
