Enzymes For Fat Digestion
What do your liver, gallbladder and pancreas all have in common? They help digest fat!
Fats are one of the major food groups needed for proper nutrition, along with protein and carbohydrates. When you eat food, your digestive system must break down the nutrients in the food by converting them to smaller molecules that your cells, organs and tissues use for hundreds of metabolic functions. Enzymes made in different parts of your digestive tract act on these smaller molecules to finalize this process.
Why Is Lipase Important
Fats must be digested properly before absorption, because fat is not water-soluble and the end products of fat digestion are carried in water substances like blood and lymph. Without lipase, the fats cannot be split into fatty acids and glycerol.
Lipase digests fat-soluble vitamins.
Lipase-deficient people may have issues with high cholesterol and high triglycerides. Some triglycerides are needed in the body for energy, but high levels are often thought to be a risk for heart disease.
Lipase requires chloride as a coenzyme. Lipase-deficient people have a tendency towards hypochloridia or low stomach acid.
Origin And Properties Of Gluten
Gluten proteins are found in wheat, which belongs to the Triticeae tribe in the Poaceae plant family . Wheat is one of the most widely consumed cereals in the world and is the greatest single source of protein in the human diet. Together with maize and rice, wheat species account for over 70% of the total cereal production worldwide . Due to their abundance, widespread distribution and consumption amongst human and animal populations, these cereals are of great nutritional and economic importance.
The structure and properties of cereal grains have been studied systematically for over 250 years. The protein content of gluten from various wheat species was among the first to be characterized. In 1745, Beccari first described the isolation of wheat gluten . Two centuries later, Osborne developed a classification system for plant-derived proteins based on their extraction and solubility in different solvents . This classification comprised the albumins , globulins , glutelins and prolamins .

Study Demonstrates Current Enzyme Supplements For Celiac Disease Ineffective
For many years, certain enzyme supplements have been touted to be able to help those with celiac disease digest gluten. As oral supplements, these enzymes are marketed to assist with breaking down the protein in gluten that those with celiac are usually unable to digest. However, a study conducted by Janssen et al, demonstrated that these commercialized enzyme supplements are actually ineffective at cutting gluten1.
People with celiac disease react to gluten because an amino acid chain in the substance binds to certain expressed genes that only those with celiac disease have. This prevents gluten from being broken down like it needs to be, allowing it to reach the small intestine. In turn, this triggers an over-reactive immune response, causing celiac disease symptoms. The common misconception about these supplements is that they are able to break down the amino acid chain that would otherwise not be digested. However, it was revealed that the commercialized enzymes cannot even survive the pH of the stomach , let alone withstand the pepsin to which they are exposed in the digestive tract. Pepsin is an enzyme released by the stomach that aids in digestion, and it is most active in acidic environments. This means that the commercialized enzymes will not properly protect against gluten exposure to improve celiac disease symptoms.

Studying The Effects Of An
The researchers led by Julia König, Ph.D., postdoctoral research fellow at the School of Medical Sciences at the University of -rebro, Sweden tested the enzyme on 18 patients that were self-reportedly gluten-sensitive.
The participants consumed a portion of porridge with two wheat cookies that contained gluten, and they were then administered either AN-PEP or a placebo. The enzyme was administered in a high dose or a low dose.
König and team monitored the levels of gluten in the stomach and small intestine over 3 hours.
The study found that both the high-dose and low-dose AN-PEP groups had 85 percent less gluten in their stomachs than the placebo group.
In the duodenum the first part of the small intestine the level of gluten was lowered by 81 percent in the high-dose group, and 87 percent in the low-dose group, compared with the placebo group.

Using Digestive Enzyme Supplements In Food Intolerance
Not only can digestive enzyme supplementation make the dietary approaches to food intolerance work better, in many cases enzyme supplementation may be more useful than dietary changes. Many people with food intolerances benefit from a 14-day trial with a high potency digestive enzyme preparation. In the 14-day challenge simply take one or two capsules of the high potency enzyme formula before each meal for 14 days. Improving digestion via supplemental enzymes is often all that is necessary to eliminate a food intolerance.
Pharmaceutical Enzyme Modification By Pegylation And Microencapsulation
Protein-based drugs hold promise as therapeutic agents because of their high specificity, but in general they often display short half-lives in vivo, either due to rapid excretion or proteolysis. Instability and auto-degradation of gluten-degrading enzymes are major challenges for their therapeutic application.
PEGylation usually improves protein stability . PEGylation was first described in 1977 as a valuable technique to stabilize catalase and albumin . PEGylation consists of covalent or non-covalent attachment of poly-ethylene-glycol to a molecule such as a therapeutic protein or to a nanocarrier, thereby enhancing its protection from proteolytic degradation or rapid excretion, thus increasing its stability in vivo . Microencapsulation is a technique of enteric coating to form microparticles that partly resist enteric degradation or allow distal delivery of the pharmacological agents or protein. Examples of biocompatible polyesters are poly copolymers . As a polymeric vehicle, predictability of degradation, ease of fabrication, and regulatory FDA approval are features that make PLGA desirable for medical applications .

Gluten And Wheat Intolerance: Do We All Lack An Enzyme To Metabolize Gluten
This question originally appeared on Quora. Answer by Matan Shelomi.
Firstly, all humans can digest gluten. All. Anything we cannot metabolize, such as cellulose passes through us and gets pooped out. Cellulose is found in all plant cells: if we only ate things we can digest, wed all be carnivores!
Gluten is a protein. We have proteases for it. We can break it down. We just cant break it down completely: one of the pieces, named gliadin, does not get broken. This is not improper digestion, thats just how we digest it. Lots of foods only get partially broken down. However, according to this Science paper, gliadin reacts with an enzyme called transglutaminase that, in Celiac patients only, triggers an autoimmune response, due to a gene mutation in these patients. For non-Celiacs, it gets pooped out and does not trigger the response. The article notes that swallowing some bacterial protease enzymes that digest gliadin further could make gluten safe for celiacs, just as lactase enzyme pills helps lactose intolerant people eat dairy . However, there is nothing improper about us not breaking down gliadin. Thats just what we do, and its normally not a problem.
Nothing here says we cannot digest gluten. The papers instead describe what happens when we do.

New Enzyme Blocks Gluten Relieves Symptoms Of Gluten Intolerance
New research may have found an enzyme that can relieve symptoms in gluten-sensitive people. The study shows that taking a tablet containing this enzyme can stop the gluten from reaching the small intestine, drastically reducing the symptoms of gluten intolerance.
Gluten is a protein mainly found in grains such as wheat, rye, and barley, as well as in certain medicines and supplements. For some people, gluten can cause severe gastrointestinal problems. Some of these people have celiac disease, while others are simply gluten sensitive.
Celiac disease is an inherited autoimmune disorder, in which the bodys immune system will start to attack the small intestine when it detects gluten.
Gluten sensitivity shares some of its symptoms with celiac disease, but unlike the latter, it does not harm the small intestine. Gluten intolerance can also cause additional symptoms, such as leg numbness or muscle cramps.
Beyond Celiac estimate that approximately 18 million people in the United States are intolerant of gluten, without having celiac disease.
A new study suggests that an enzyme called aspergillus niger-derived prolyl endoprotease can stop gluten from entering the small intestine, reducing the symptoms in gluten-sensitive patients.
The findings were presented at Digestive Disease Week 2017, an international conference that gathers specialists in the fields of gastroenterology, endoscopy, hepatology, and gastrointestinal surgery.

Celiac Disease Drug Pipeline
Based on results of the Phase 1 study, Takeda in February bought the PVP Biologics, the company that was developing the enzyme, for a pre-negotiated upfront payment as well as development and regulatory milestones totaling up to $330 million, according to Takeda. Takeda and PVP had a previous agreement under which PVP was responsible for research and development through Phase 1 in exchange for initial funding from Takeda.
The drug, formerly called Kuma-062, got its start as a project by students at University of Washington, Seattle, some of whom had friends who had celiac disease. The team of undergraduate students won a prestigious international biological science competition for their work on Kuma-062.
Enzymes Do Not Change The Nature Of Celiac Disease And Do Not Treat Or Cure It
Existing data is very encouraging and clearly proves that AN-PEP enzymes greatly reduce the concentration of gliadin and can possibly even make it undetectable. It is important to note, that these enzymes do not change the nature of celiac disease and therefore do not treat or cure it. They can only break down the molecule that is triggering a reaction and therefore help maintain a gluten-free diet when contaminants are present. Essentially, there are two ways to maintain a gluten-free diet. One way is to avoid any contaminants in the food but most authorities agree that this is almost unattainable. The second way, is to break down the contaminants before they can cause damage. The underlying immune-deficiency is not changed and adherence to a gluten-free diet can not be neglected. Clinicians are reluctant to recommend enzymes for gluten contamination and certainly not for intentional consumption without regulatory approval.

Other Research Supports Rothia Breaks Down Gluten
A 2011 study from Boston University tested Rothia mucilaginosa and Rothia aeria bacteria derived from the intestinal tract. Again, the researchers found that gluten and gliadin proteins were broken down by these bacteria. The researchers stated:
While the human digestive enzyme system lacks the capacity to cleave immunogenic gluten, such activities are naturally present in the oral microbial enzyme repertoire. The identified bacteria may be exploited for physiologic degradation of harmful gluten peptides.

Challenge Of Glutenase Therapy For Celiac Disease
Gluten-degrading enzymes, can both increase and decrease gluten peptide immunogenicity, as illustrated by peptidases and prolyl endopeptidases produced by commensals in the human GI tract. The increase of immunogenicity can be explained by the generation of gluten peptide fragments that more easily enter the small intestinal lamina propria than the larger immunogenic peptides produced by the human gastrointestinal proteases. An example is an enzyme produced by Pseudomonas that increased the number of smaller immunogenic peptides, while only the additional activity of the Lactobacillus protease then leads to smaller non-immunogenic gluten fragments . Therefore, therapeutic glutenases must be able to rigorously degrade immunogenic epitopes before they reach the proximal small intestinal mucosa.
