What is Amylase?
Amylase-Digesting Carbohydrates
Amylase is an enzyme in the class of digestive enzymes that breaks starch down into sugar. Salivary amylase is present in human saliva, where it begins the chemical process of digestion. 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.
The pancreas also makes amylase (alpha amylase) to break down dietary starch into di- and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase.
As a digestive enzyme Amylase supplements have a combination of Protease (breaks down protein), amylase (breaks down starch), lipase (breaks down fat), cellulase (breaks down fiber).
Digestive Enzyme Amylase
Amylase is a digestive enzyme found in pancreatic juice and saliva, and is what the body needs to break down sugars and starches. It also clings to carbohydrates and eventually converts them to monosaccharides such as glucose. Carbohydrates can be stored in the body as glycogen, the polymeric form of glucose, for future use.
If carbohydrates are eaten in excessive amounts, the body changes them into fats and stores them in that form. Amylase is also found during the ripening process of fruit plants where it synthesizes and gives the fruit a sweeter taste.
Amylase enzymes are used extensively in bread making to break down complex sugars such as starch (found in flour) into simple sugars.
Amylase and Carbohydrates digestion; The process of digesting carbohydrates begins in the mouth. Our saliva contains an enzyme called amylase that starts breaking down the more complex carbs into simpler types. Enzyme activity continues in the stomach, but slows down significantly as digestive acids are released into the stomach by the glands.
Another version of amylase is secreted by the pancreas into the duodenum (first section of small intestine). This cuts down carbohydrates into simple sugars – maltose, lactose and sucrose. As the carbohydrate passes further into the intestine, the enzymes chop maltose lactose and sucrose into smaller bits,to be more easily absorbed, which are eventually converted to glucose and absorbed through the intestinal walls into the bloodstream.
After carbohydrates are broken down into glucose, in the duodenum and jejunum of the small intestine, the glucose is absorbed into the bloodstream and taken to the liver, where it is stored or distributed to cells throughout the body for energy. In this way, the liver regulates levels to provide sufficient energy for the body.
Amylase-How are carbohydrates broken down into glucose?
For example, excess glucose (a cause of hyperglycemia) is converted in the liver to glycogen (glycogenolysis) in response to the hormone insulin, and stored. Likewise, if blood sugar levels fall, (eg. between meals), the glycogen is re-converted to glucose (glycogenolysis) in response to messages conveyed by the hormone glucagon, to prevent hypoglycemia. If glycogen levels are exhausted, glucagon can trigger the formation of glucose from some amino acids (protein) or glycerol (fats) – a process called gluconeogenesis.
Amylase-How We “Digest Carbohydrates”
In simple terms, the digestive system from the mouth to the small intestine (carbohydrates digested in digestive system) is designed to break down disaccharides and polysaccharides into monosaccharides.
This metabolism of carbohydrates is achieved through the secretion of a number of digestive enzymes into the gastrointestinal tract “intestinal digestion” (especially in the duodenum) where they attack carbohydrates and gradually convert them into simple sugars like glucose so they can be absorbed into the blood.
Digestive enzymes are involved in digesting carbohydrates
Digestive enzymes are like biological scissors – they chop long starch molecules into simpler ones. Sometimes our bodies require the help of “digestive aids”
Amylase-What Determines Speed of “Digesting Carbohydrates”?
Generally speaking, the speed of carbohydrate digestion is determined by the chemical nature of the carbohydrate itself, and thus how “resistant” it is to the activity of the enzymes.

A simple sugar is much less resistant than a starch, and is digested or metabolized much faster. Poor digestion, Things that slow down carbohydrate digestion include: the presence of acid (from gastric juices or the food itself), and the presence of soluble fiber.
Carbohydrates are a class of natural organic substances that includes sugars, starch and cellulose (indigestible plant fiber).
The digestion of a particular carbohydrate in the gastrointestinal tract depends upon the complexity of the carbs molecular structure – the more complex it is, the harder the digestive system must work to break it down in order to absorb it into the bloodstream.
Bacilliary amylase is used in detergents to dissolve starches from fabrics.
An inhibitor of alpha-amylase called phaseolamin has been tested as a potential diet aid for weight loss. (Phaseolamin is a generic name for a proteinaceous inhibitor of the enzyme alpha-amylase that is made from white kidney bean extract.)
Blood serum amylase may be measured for purposes of medical diagnosis. A normal concentration is in the range 21-101 U/L. A higher than normal concentration may reflect one of several medical conditions, including acute inflammation of the pancreas, macroamylasemia, perforated peptic ulcer, and mumps. Amylase may be measured in other body fluids, including urine and peritoneal fluid.
Amylase tests can help diagnose many diseases where Amylase levels are elevated, and Amylase tests are done on both blood and urine when there is sudden abdominal pain. Pancreatitis is the main reason Amylase levels increase, but mumps infections can cause a rise as well.
Other culprits could be ulcers, gall bladder disease, tumors of the lung or ovaries, alcohol poisoning, ruptured aortic aneurysm, and intestinal strangulation or perforations. People who cannot digest fats often eat sugar and carbohydrates to make up for the lack of fat in their diet, but doing so can often lead to an Amylase deficiency.
Amylase Supplements For Weight Loss
Alpha-amylase is a digestive enzyme that breaks down starch into smaller carbohydrate units that can subsequently be broken down into the simple sugar, glucose. Glucose is absorbed directly into the bloodstream following its uptake by intestinal cells, resulting in a relatively rapid rise in serum glucose levels. Glucose is used by all cells of the body to fuel metabolism. Excess glucose, however, can be converted into fat and stored in adipose tissue.
