Amylases. Amylases are starch-degrading enzymes that catalyze the hydrolysis of internal α-1-4 glycosidic bonds in polysaccharides to form simpler sugar constitutes and limit dextrins.
How carbohydrates are digested?
Digestion of Carbohydrates During digestion, starches and sugars are broken down both mechanically (e.g. through chewing) and chemically (e.g. by enzymes) into the single units glucose, fructose, and/or galactose, which are absorbed into the blood stream and transported for use as energy throughout the body.
Where carbohydrates are digested?
Carbohydrate digestion begins in the mouth and is most extensive in the small intestine. The resultant monosaccharides are absorbed into the bloodstream and transported to the liver.
What enzyme breaks the carbohydrates into sugar?
The mouth Saliva releases an enzyme called amylase, which begins the breakdown process of the sugars in the carbohydrates you're eating.
How does the body break down carbohydrates?
When you eat carbs, your body breaks them down into simple sugars, which are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin. Insulin is needed to move sugar from the blood into the cells, where the sugar can be used as a source of energy.

Why is amylase important?
By maintaining healthy glucose levels, amylase helps to prevent the conditions that characterize the metabolic syndrome. Amylase has also been incorporated into holistic approaches to treating cancer. The idea is to balance blood glucose and correct nervous system imbalances that weaken the immune function.
What happens when carbohydrates get to the intestines?
Once carbohydrates get to the intestines, digestion resumes, as amylase produced by the pancreas is now available and creates glucose. Any disruptions to this carbohydrate breakdown can result in health complications. For example, low glucose levels in the blood can cause fatigue and muscle weakness.
Why is it important to keep amylase levels up?
Like most things, amylase production slows as we get older, which increases our risk for digestive troubles, malnutrition, and poor health. It is therefore important to keep levels up as we get older, and this can be easily done through plant-based digestive enzyme supplements as well as eating a variety of foods, including:
Why do we need amylase?
Because you need carbohydrates, you also need amylase enzymes. The effects of amylase can be seen much quicker than those of lipase digestive enzymes (helps digest fats) and protease (helps digest proteins). The reason for this is because amylase comes from two locations in your body—the pancreas and the salivary glands.
What are the enzymes that help the body absorb nutrients?
Organic digestive enzymes, like amylase, are naturally produced by your body and play a critical role in nutrient absorption. Without them, malnutrition and poor health can result.
Where does amylase come from?
The reason for this is because amylase comes from two locations in your body—the pancreas and the salivary glands . The breakdown of carbohydrates begins in the mouth with your saliva, but when they get to the stomach, the amylase is neutralized by stomach acid, and the breakdown of carbohydrates ceases.
Which organs make amylase?

What are the amylases in beer?
α- and β-amylases are important in brewing beer and liquor made from sugars derived from starch. In fermentation, yeast ingests sugars and excretes ethanol. In beer and some liquors, the sugars present at the beginning of fermentation have been produced by "mashing" grains or other starch sources (such as potatoes ). In traditional beer brewing, malted barley is mixed with hot water to create a " mash ", which is held at a given temperature to allow the amylases in the malted grain to convert the barley's starch into sugars. Different temperatures optimize the activity of alpha or beta amylase, resulting in different mixtures of fermentable and unfermentable sugars. In selecting mash temperature and grain-to-water ratio, a brewer can change the alcohol content, mouthfeel, aroma, and flavor of the finished beer.
Why does amylase taste sweet?
Foods that contain large amounts of starch but little sugar, such as rice and potatoes, may acquire a slightly sweet taste as they are chewed because amylase degrades some of their starch into sugar.
Why is amylase important in molecular biology?
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. 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 .

Overview
Evolution
Saccharides are a food source rich in energy. Large polymers such as starch are partially hydrolyzed in the mouth by the enzyme amylase before being cleaved further into sugars. Many mammals have seen great expansions in the copy number of the amylase gene. These duplications allow for the pancreatic amylase AMY2 to re-target to the salivary glands, allowing animals to detect starch by taste and to digest starch more efficiently and in higher quantities. T…
Classification
The α-amylases (EC 3.2.1.1 ) (CAS 9014-71-5) (alternative names: 1,4-α-D-glucan glucanohydrolase; glycogenase) are calcium metalloenzymes. By acting at random locations along the starch chain, α-amylase breaks down long-chain saccharides, ultimately yielding either maltotriose and maltose from amylose, or maltose, glucose and "limit dextrin" from amylopectin. They belong to glycoside hydrolase family 13.
Uses
