Trypsin is an enzyme that aids with digestion. An enzyme is a protein that speeds up a certain biochemical reaction. Trypsin is found in the small intestine. It can also be made from fungus, plants, and bacteria. But it is usually made for commercial purposes from the pancreas of livestock.

Trypsin is given to people who lack enzymes needed for digestion.

It is also given in combination with bromelain and rutin for treatment of osteoarthritis and many other conditions, but there is no good scientific evidence to support these other uses.

Some people apply trypsin directly to wounds and ulcers to remove dead tissue and improve healing.


Is a Form of:


Primary Functions:


Also Known As:

Enzyme Protéolytique, Proteinase, Protéinase

How Does It Work?

Trypsin removes dead skin cells (tissue) and allows healthy tissue to grow. Trypsin in combination with other enzymes seems to reduce inflammation and swelling.

  • Colon cancer, rectal cancer.
  • Diabetes.
  • Improving digestion.
  • Infections of the kidney, bladder, or urethra (urinary tract infections or UTIs).
  • Multiple sclerosis (MS).
  • Muscle soreness caused by exercise.

Recommended Dosing

The appropriate dose of trypsin depends on several factors such as the user's age, health, and several other conditions. At this time, there is not enough scientific information to determine an appropriate range of doses for trypsin. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.

Trypsin Supplements Frequently Asked Questions

What is trypsin used for?

Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. It may also be referred to as a proteolytic enzyme, or proteinase. Trypsin is produced by the pancreas in an inactive form called trypsinogen.

What does trypsin inhibitor do?

A trypsin inhibitor (TI) is a protein and a type of serine protease inhibitor (serpin) that reduces the biological activity of trypsin by controlling the activation and catalytic reactions of proteins.

What is the function of trypsin and chymotrypsin?

Trypsin and chymotrypsin are important digestive enzymes that are secreted by the pancreas as the inactive enzyme precursors trypsinogen and chymotrypsinogen. Trypsin activates itself via positive feedback and converts chymotrypsinogen and other inactive enzymes into their active forms.

How do you get trypsin?

Trypsin is produced from proenzyme, trypsinogen secreted by exocrine cells of pancreas; Trypsin acts on C-terminal side of Lysine or Arginine. Optimum activity is achieved at 37oC, so pre-warmed trypsin speed up the detachment.

Does trypsin kill cells?

Long term incubation with high trypsin concentration damage cells by striping cell surface proteins and kill the cells. Trypsin is tolerated by many cell types; however it is desirable to avoid trypsin in proteomic studies and serum-free cultures.

What foods contain trypsin?

Trypsin inhibitors are widely distributed across many genera and species in the Leguminoseae family and many other plant families; TIA has also been found in a range of legumes, including red gram, kidney beans, navy beans, black-eyed peas, peanuts, field beans, French beans, and sweet peas, and in all varieties tested .

What neutralizes trypsin?

Trypsin Neutralization Solution (TNS) is a sterile, phosphate and HEPES-buffered saline solution used to neutralize the effects of Trypsin/EDTA solution (T/E; Cat. #0103) after the release of cells from a culture surface.

How is trypsin deactivated?

Trypsin is inhibited by serum that provides the divalent cations like calcium and magnesium which plays a role in both intra and intercellular signalling process i.e. forming CAMs, so serum is usually added to the container once cells have detached - this can be confirmed by observation under a microscope.

How does trypsin cause pancreatitis?

There may be a disruption of calcium signaling in acinar cells or breakdown of trypsinogen to trypsin by the enzyme lysosomal hydrolase cathepsin-B or decreased activity of the intracellular pancreatic trypsin inhibitor. Once activated trypsin in turn activates several pancreatic digestive enzymes.

What is the difference between trypsin and chymotrypsin?

The main difference between chymotrypsin and trypsin is the amino acids they select for. Chymotrypsin is the enzyme that selects for the aromatic amino acids: phenylalanine, tryptophan, and tyrosine. Trypsin is the enzyme that selects for the basic amino acids: lysine and arginine.

How long does trypsin last?

If you want to keep it for longer period, you should prepare it according to the description given by your furnisher. As example for a Trypsin from bovine pancreas (Product Number T 4665, SIGMA-ALDRICH), "solutions in 1 mM HCL (pH 3) are stable for approximately 1 year when aliquoted and stored at -20°C.

How does trypsin kill cells?

Various proteolytic enzymes are used to detach cells from the adherent substrate, of which the trypsin a member of serine protease family is most frequently used. Long term incubation with high trypsin concentration damage cells by striping cell surface proteins and kill the cells.

What happens if trypsin is not present?

Malabsorption. If your pancreas doesn't produce enough trypsin, you can experience a digestive issue called malabsorption — the decreased ability to digest or absorb nutrients from food. In time, malabsorption will cause deficiencies in essential nutrients, which can lead to malnutrition and anemia.

What happens if you leave cells in trypsin for too long?

Incubating cells with too high a trypsin concentration for too long a time period will damage cell membranes and kill the cells. If unsure about the concentration of trypsin to use, use a low concentration.

Is trypsin toxic to cells?

Long term incubation with high trypsin concentration damage cells by striping cell surface proteins and kill the cells. Trypsin is tolerated by many cell types; however it is desirable to avoid trypsin in proteomic studies and serum-free cultures.

How much media do you need to neutralize trypsin?

In some protocol, the ratio of 10%FBS media to 0.25%trypsin-EDTA is 1:1 or 2:1. ATCC guide uses 3:1. So what is minimum or the best ratio of FBS to inactivate trypsin.

What causes high trypsin levels?

Massive invasion of gastric cancer to the pancreas may release the pancreatic trypsin(ogen) into blood, increasing its serum level.

Why is trypsin important?

Trypsin is a proteolytic enzyme, important for the digestion of proteins. In humans, the protein is produced in its inactive form, trypsinogen, within the pancrease. Trypsinogen enters the small intestine, via the common bile duct, where it converted to active trypsin.

What protein does trypsin break down?

In the duodenum, trypsin catalyzes the hydrolysis of peptide bonds, breaking down proteins into smaller peptides. The peptide products are then further hydrolyzed into amino acids via other proteases, rendering them available for absorption into the blood stream.

How is trypsin inactivated in culture?

Trypsinization is the process of cell dissociation using trypsin, a proteolytic enzyme which breaks down proteins, to dissociate adherent cells from the vessel in which they are being cultured. When added to a cell culture, trypsin breaks down the proteins which enable the cells to adhere to the vessel.

Why does serum inactivate trypsin?

Trypsin is an endopeptidase, which digests proteins. In the trypsinization process extracellular proteins are digested, which leads to the detachment of the cells from the bottom of the culture vessel. Serum contains many protease inhibitors, which are stopping trypsin, mostly alpha-1-antitrypsin. Hope this helps!

What kind of enzyme is trypsin?

Trypsin is a pancreatic serine protease with substrate specificity based upon positively charged lysine and arginine side chains (Brown and Wold 1973). The enzyme in excreted by the pancreas and takes part in the digestion of food proteins and other biological processes.
