Here you have a list of opinions about Digestive enzyme and you can also give us your opinion about it. You will see other people's opinions about Digestive enzyme and you will find out what the others say about it.
Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body. In the human digestive system, the main sites of digestion are the oral cavity, the stomach, and the small intestine. In the image below, you can see a graph with the evolution of the times that people look for Digestive enzyme. Thanks to this graph, we can see the interest Digestive enzyme has and the evolution of its popularity.

The diagram to the left is of the alimentary canal also known as the digestive tract and also shows other organs of the digestive system like the liver. After being swallowed, the food travels down the Oesophagus or esophagus, this is continually being damaged by the friction of food, so the epithelium is a few cells thick and secretes mucas to lubricate the food's passage.
The next place it enters is the stomach this is a temporary store, mixes the contents up and also is the site for a bit of digestion.
Enzymes are sensitive to temperature and pH, these must be at an optimum level so they work best. Below is a digram of the human gut wall, on the right are labelled the different layers that exist.
The first actual layer is the mucosa, it has a layer of epithelium, made of epithelial cells, which have projections called villi.
Below this is a muscle layer, known scientifically as the muscularis externa, it is reponsible for peristalsis which moves food through the digestive tract.
In the diagram you should also notice the capillaries, part of the blood network which takes absorbed food away. By the time everything reaches here, the food has been digested into small enough particles that it can pass through the alimentary tract lining and be absorbed into the blood.
The food products pass into the blood stream through villi: these are small foldings of the small intestine that cover on its internal surface. The villi on their own increase the surface area, but the cells which make up the surface of the villus have their own small projections called microvilli (see diagram) these further increase the surface area which means that the digestion products can be absorbed more quickly. The villus has a supply of blood vessels this means substances absorbed can be transported to where they are needed more directly.
Triglycerides are a type of lipid; here you will learn how the body breaks down this molecule. Digestion begins in the duodenum where bile enters from the liver, bile salts make the big blobs of fat into small micelle droplets which massively increases the surface area and makes digestion much easier.
Also in the duodenum, pancreatic lipase this breaks the triglyceride into fatty acid and glycerol.
These resynthesised lipids make proteins called chylomicrons, these enter the lacteals and travel through the lymphatic system, making it milky. Other dietary sugars such as sucrose and lactose (both disaccharides) are broken down further by different carbohydrase enzymes.


NOTE: Ita€™s important you recall the main digestive enzymes, the food types they break down and where they are produced.

Amylase enzymes find use in bread making and to break down complex sugars such as starch (found in flour) into simple sugars.
When used as a food additive Amylase has E number E1100, and may be derived from swine pancreas or mould mushroom. Bacilliary amylase is also used in clothing and dishwasher detergents to dissolve starches from fabrics and dishes. Workers in factories that work with amylase for any of the above uses are at increased risk of occupational asthma.
In molecular biology, the presence of amylase can serve as an additional method of selecting for successful integration of a reporter construct in addition to antibiotic resistance.
Trypsin is secreted into the duodenum, where it acts to hydrolyse peptides into their smaller building-blocks, namely amino acids (these peptides are the result of the enzyme pepsin's breaking down the proteins in the stomach). A lipase is a water-soluble enzyme that catalyzes the hydrolysis of ester chemical bonds in water-insoluble lipid substrates.[1] Lipases are a subclass of the esterases.
Lipases perform essential roles in the digestion, transport and processing of dietary lipids (e.g. Most lipases act at a specific position on the glycerol backbone of lipid substrate (A1, A2 or A3)(small intestine). Several other types of lipase activities exist in nature, such as phospholipases[5] and sphingomyelinases[6], however these are usually treated separately from "conventional" lipases. Protein Digestion by TrypsinTrypsin, an enzyme produced by the pancreas, hydrolyzes proteins to small fragments (proteoses, peptones, and peptides). The dispersion of food fat into micelles thus provide a largely increased surface area for the action of the enzyme pancreatic lipase, which actually digests the triglycerides, and is able to reach the fatty core through gaps between the bile salts. Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances, such as the vitamins D, E, K and A. Besides its digestive function, bile serves also as the route of excretion for bilirubin, a byproduct of red blood cells recycled by the liver. The alkaline bile also has the function of neutralizing any excess stomach acid before it enters the ileum, the final section of the small intestine. Digestive enzymes are found in the digestive tracts of animals (including humans) and in the traps of carnivorous plants, where they aid in the digestion of food, as well as inside cells, especially in their lysosomes, where they function to maintain cellular survival. And below it, you can see how many pieces of news have been created about Digestive enzyme in the last years. Proteins are long chains of amino acids, and protease enzymes break them into peptides (smaller chains of amino acids molecules) and eventually into individual amino acids, which are small and easily absorbed in the small intestine. It digests complex fat (or lipid) molecules into simple, soluble fatty acid and glycerol molecules.
Yeast then feeds on these simple sugars and converts it into the waste products of alcohol and CO2. As reporter genes are flanked by homologous regions of the structural gene for amylase, successful integration will disrupt the amylase gene and prevent starch degradation, which is easily detectable through iodine staining. Trypsin cleaves peptide chains mainly at the carboxyl side of the amino acids lysine or arginine, except when either is followed by proline.


This enables the uptake of protein in the food because peptides (though smaller than proteins) are too big to be absorbed through the lining of the ileum.
When the pancreas is stimulated by cholecystokinin, it is then secreted into the small intestine. For example, human pancreatic lipase (HPL),[4] which is the main enzyme that breaks down dietary fats in the human digestive system, converts triglyceride substrates found in ingested oils to monoglycerides and free fatty acids.
In particular, Candida albicans has a large number of different lipases, possibly reflecting broad lipolytic activity, which may contribute to the persistence and virulence of C. BAPNA is a synthetic (man-made) protein substrate consisting of a dye covalently bound to an amino acid. Bile salt anions have a hydrophilic side and a hydrophobic side, and therefore tend to aggregate around droplets of fat (triglycerides and phospholipids) to form micelles, with the hydrophobic sides towards the fat and hydrophilic towards the outside. A triglyceride is broken down into two fatty acids and a monoglyceride, which are absorbed by the villi on the intestine walls. Bile salts also act as bactericides, destroying many of the microbes that may be present in the food.
Digestive enzymes are diverse and are found in the saliva secreted by the salivary glands, in the stomach secreted by cells lining the stomach, in the pancreatic juice secreted by pancreatic exocrine cells, and in the intestinal (small and large) secretions, or as part of the lining of the gastrointestinal tract.
Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. Once in the small intestine, the enzyme enteropeptidase activates it into trypsin by proteolytic cleavage. Trypsin hydrolysis of BAPNA cleaves the dye molecule from the amino acid, causing the solution to change from colorless to bright yellow. The hydrophilic sides are positively charged due to the lecithin and other phospholipids that compose bile, and this charge prevents fat droplets coated with bile from re-aggregating into larger fat particles. After being transferred across the intestinal membrane, fatty acids are reformed into triglycerides, then absorbed into the lymphatic system through lacteals.
The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy.
The resulting trypsins themselves activate more trypsinogens (autocatalysis), so only a small amount of enteropeptidase is necessary to start the reaction. Since the covalent bond between the dye molecule and the amino acid is the same as the peptide bonds that link amino acids together, the appearance of a yellow color indicates the presence and activity of an enzyme that is capable of peptide bond hydrolysis. Without bile salts, most of the lipids in the food would be passed out in feces, undigested. This activation mechanism is common for most serine proteases, and serves to prevent autodigestion of the pancreas.
Because the color change from clear to yellow is direct evidence of hydrolysis, additional tests are not required when determining trypsin activity using BAPNA. As diastase, amylase was the first enzyme to be discovered and isolated (by Anselme Payen in 1833).[1] Specific amylase proteins are designated by different Greek letters.
