Pancreatic juice

What is pancreatic juice?

Pancreatic juice is the pancreatic exocrine fluid, which enters into the duodenum to implement its pancreatic exocrine function - digest the food and nutrients.

Components of pancreatic juice

The pancreatic juice consists of a clear, alkaline (pH 7.5-8.4) solution of 750-1500 ml/d containing digestive enzymes.

PH of pancreatic juice: 7.5~8.4.

Pancreatic juice contains: water and electrolytes - HCO3-, others like Na+, K+, Ca2+, Mg2+, HPO42+, and a variety of digestive enzymes.

Pancreatic juice enzymes: also called pancreatic digestive enzymes, including:

In addition, pancreatic juice also contains trypsin inhibitors, that can prevent trypsinogen from being activated within the pancreas, thus avoiding the occurrence of pancreatitis.

Pancreatic juice function

The pancreatic juice contains a large amount of HCO3-, that can protect your intestinal wall from being destroyed by stomach acid. It is a so-called acid-base neutralization reaction, and therefore provides the best working environment (alkaline environment, Ph 7.5~8.5) for digestive enzymes to digest food. These pancreatic enzymes contained in pancreatic juice play an important role to break down fat, protein and starch for nutrient absorption.
