Molecule of the Month. Trypsin An activated serine amino acid in trypsin cleaves protein chains Serine proteases: trypsin top , chymotrypsin center , and elastase bottom. Your body needs a steady supply of amino acids for use in growth and repairs. Each day, a typical adult needs something in the range of grams of protein, depending on their weight. Quite surprisingly, a large fraction of this may come from inside. A typical North American diet may contain grams of protein each day.
But your body also secretes grams of digestive proteins, which are themselves digested when they finish their duties. Dead intestinal cells and proteins leaking out of blood vessels are also digested and reabsorbed as amino acids, showing that our bodies are experts at recycling.
Proteins are tough, so we use an arsenal of enzymes to digest them into their component amino acids. Digestion of proteins begins in the stomach, where hydrochloric acid unfolds proteins and the enzyme pepsin begins a rough disassembly.
The real work then starts in the intestines. The pancreas adds a collection of protein-cutting enzymes, with trypsin playing the central role, that chop the protein chains into pieces just a few amino acids long. Then, enzymes on the surfaces of intestinal cells and inside the cells chop them into amino acids, ready for use throughout the body. Trypsin uses a special serine amino acid in its protein-cutting reaction, and is consequently known as a serine protease.
The serine proteases are a diverse family of enzymes, all of which use similar enzymatic machinery. In digestion, trypsin, chymotrypsin and elastase work together to chop up proteins. Each has a particular taste for protein chains: trypsin shown at the top from PDB entry 2ptn cuts next to lysine and arginine, chymotrypsin shown in the middle from PDB entry 2cha cuts next to phenylalanine and other large amino acids, and elastase likes chains with small amino acids like alanine shown at the bottom from PDB entry 3est.
Although some studies have shown that trypsin in combination with other digestive enzymes did not induce any side effects, there have not been sufficient reports of trypsin taken alone by mouth and its safety level. Mild side effects, such as local pain and temporary burning sensation have been noted when trypsin was applied to the skin for wound treatment.
Discomfort of the GI tract has been commonly reported from over-the-counter enzymes, taken by mouth, particularly at high doses. There are rare reports of a severe allergic reaction, called anaphylaxis that were linked with oral chymotrypsin. These signs of anaphylactic shock are considered a medical emergency.
If a person experiences these symptoms after taking trypsin or any other medication or natural supplement they should seek immediate emergency medical care. A contraindication is a specific medication, treatment or other situation in which a drug, supplement or treatment should not be given because of its potential to cause harm. Contraindications those who should not take a drug or supplement because of its potential to cause harm for trypsin include:.
Trypsin can be made from bacterial or fungal sources but it is most often extracted from the pancreas of pigs called porcine trypsine.
It can also be made from other meat-producing animal sources. Most commercially sold trypsin supplements are combined with other enzymes. The average oral dose of trypsin is up to 50 milligrams mg and is most often combined with bromelain another proteolytic enzyme. The Dietary Supplement Health and Education Act of deemed over-the-counter enzymes as dietary supplements. This means that they are exempt from being mandated to prove the safety or efficacy of their products as opposed to prescription or over-the-counter medications.
This provision is in place, provided the manufacturer does not make any claims that the product can treat, prevent or cure a disease. In addition, dietary supplements are not regulated by a government agency such as the Food and Drug Administration FDA. What this means is that the burden of establishing safety, purity, and efficacy of a natural supplement lies with the consumer, and not the manufacturer.
Because these supplements are not strictly regulated, they could have contaminants. To help ensure that products, such as trypsin, are safe, your healthcare provider should always be consulted regarding the indication, dosage, and duration before they are taken. In addition, when purchasing proteolytic enzymes, such as trypsin, be sure to select a product that is enteric-coated. An enteric coating protects the supplement from being broken down and rendered inactive by the stomach acid before it reaches the small intestine where it will go to work.
What is the difference between trypsin and chymotrypsin? A primary difference between the two enzymes is that they break down different amino acids.
Chymotrypsin breaks down tryptophan, phenylalanine, and tyrosine. Trypsin breaks down lysine and arginine. Keep in mind that just because the clinical research data is lacking, this does not indicate that products do not work; it simply means that consumers should use them with caution. As more studies become available in the future, the purported benefits may become more appealing. However, it takes time, as well as many human studies to ensure the safety and efficacy of supplements across all populations including kids, the elderly, those with medical conditions and more.
Despite the fact that the data from clinical research studies is lacking when it comes to the safety and efficacy of proteolytic enzymes such as trypsin , many people choose to take them. Trypsin and other digestive enzymes are commonly taken to treat conditions such as digestive disorders. If you intend to try trypsin or other enzymes be sure to inform your healthcare provider particularly if you have a health condition or are taking other supplements or medications.

Ask your healthcare provider what your test results mean for you. The test is done with a blood sample. A needle is used to draw blood from a vein in your arm or hand. Having a blood test with a needle carries some risks. These include bleeding, infection, bruising, and feeling lightheaded.
When the needle pricks your arm or hand, you may feel a slight sting or pain. Afterward, the site may be sore. You don't need to prepare for this test. Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illegal drugs you may use.

Why do I need this test? Symptoms of acute pancreatitis include: Pain in your upper belly that can come on quickly and last for days. Fever Nausea and vomiting, which can last for hours Agitation Chronic pancreatitis can cause many of the same symptoms, as well as some that are different.
