Question

what is pancreatic juice

Answer 1

Pancreatic juice is an alkaline digestive juice and is secreted by pancreas. This juice get mixed with the food which breaks the various macro-nutrients into simpler form.

On daily basis, nearly 200ml to 800ml by pancreasThe enzymes, such as trypsin, lipase, and amylase, are essential for the digestion of most of the protein, fat, and carbohydrate in the meal. Secretion of pancreatic juice is stimulated by hormones of the duodenum, such as secretin and cholecystokinin, and by nervous impulses through the vagus nerve.

`$\textbf{Pancreatic Juice}$`

Pancreatic juice is secreted by pancreas. Pancreas is long and yellow in colour. It is situated behind the stomach. It consists of head, body and tail.

The pancreatic juice is alkaline in nature. About 1 litre of pancreatic juice secreted daily in our body. It contains trypsinogen, chymotrypsinogen and procarboxypeptidases (three proenzymes), sodium bicarbonate and enzymes namely; amylase, pancreatic lipase, and nucleases.

* The sodium bicarbonate helps to neutralize the acid coming from stomach.

* Pancreatic lipase helps to digest fats.
Fat (triglyceride) ------› Glycerol + Fatty acid.

* Pancreatic amylase helps to digest starch.
Starch (in the presence of amylase) -----› Maltose
Starch ------› Isomaltose
Starch ------› Dextrin

* Trypsinogen is a inactive form. Euterokinase is a non enzyme helps to activate trypsinogen.

* Chemotropism is also a inactive form. Trypsin activate chotrypsinogen to chymotrypsin.
Protein (in the presence of chemotropisn) ------› Dipeptide

* Procarboxypeptidases is also a inactive form. Trypsin activates procarboxypeptidases into carboxypeptide.
Dipeptide (in the presence of carboxypeptide) -----› Amino acid.

The pH value of pancreatic juice is 8.6. The juice acts on fats, nucleic acid, starch etc. are the types of food on which it acts.
