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:
- Pancreatic lipase
- Pancreatic phospholipase
- Cholesterol esterase
- DNA enzyme
- RNA enzymes
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.
