Target data

Function

Calcium-binding enzyme that initiates starch digestion in the oral cavity (PubMed:12527308). Catalyzes the hydrolysis of internal (1->4)-alpha-D-glucosidic bonds, yielding a mixture of maltose, isomaltose, small amounts of glucose as well as small linear and branched oligosaccharides called dextrins (PubMed:12527308).

Notes

Amylase Assay Kit (Colorimetric) ab102523 detects activity of α-amylase through a two-step reaction.

In the amylase assay protocol, alpha-Amylase will cleave the substrate ethylidene-pNP-G7 to produce smaller fragments that are eventually modified by alpha-glucosidase. This causes the release of a chromophore that can then be measured at OD = 405 nm.

The assay can detect α-amylase content as low as 0.2 mU.

Amylase assay protocol summary:
- add samples and standards to wells
- add reaction mix
- analyze with a microplate reader every 2-3 min for 30-60 min

This product is manufactured by BioVision, an Abcam company and was previously called K711 Amylase Activity Colorimetric Assay Kit. K711-100 is the same size as the 100 test size of ab102523.

Amylases are enzymes that break starch down to sugar molecules. α-amylase is the major form of amylase found in humans and other mammals as well as an enzyme present in seeds, or in fungi (baker's yeast for instance). α-amylase is a calcium metalloenzyme, completely unable to function in the absence of calcium. In human physiology, both the salivary and pancreatic amylases are major digestive enzymes.

Activity summary

Amylase also known as alpha-amylase when referring to its most common form is an enzyme that plays an important role in the digestion of carbohydrates. It mechanically functions by catalyzing the hydrolysis of starch into sugars. Amylase is expressed heavily in the salivary glands and pancreas with pancreatic amylase having a molecular weight of approximately 50 kDa. These tissues produce amylase that gets released into the digestive tract where it continues the process of breaking down complex carbohydrates.

Biological function summary

Amylase is integral to the digestive process by contributing to the breakdown of starches necessary for nutrient absorption. It exists mainly as a single chain protein but in some organisms it can be part of larger multi-enzyme complexes. Its enzymatic activity significantly affects how well organisms obtain energy from their food sources. Several amylase activity assays have been developed to measure how active the enzyme is in various conditions providing insights into its role in metabolism and other biological processes.

Pathways

The function of amylase fits into the carbohydrate digestion and absorption pathway. This metabolic pathway involves other critical enzymes such as maltase and glucosidase which further break down sugar molecules. Amylase activity is key in the early stages of the pathway where it breaks down large polysaccharides into maltose and dextrins. Understanding this pathway can provide insights into nutrient absorption and energy production in organisms.

Associated diseases and disorders

Altered amylase levels connect to conditions such as pancreatitis and salivary gland dysfunction. Pancreatic amylase levels may rise in response to acute pancreatitis providing an important biomarker for diagnosing this condition. In these diseases amylase interacts with other enzymes like lipase which can also show altered activity to indicate changes in pancreatic health. Monitoring amylase activity through amylase assay kits and protocols can offer essential information for clinicians dealing with digestive and metabolic disorders.

    Functional Studies - Amylase Assay Kit (Colorimetric) (ab102523)

    Plasma amylase levels were measured (using ab102523) after 75 days treatment with saline or one of three drugs. ND, normal chow diet; HFD, high fat diet. p≤0.05, *; p≤0.01, **, n = 3–7 mice.

    There were no statistically significant changes in plasma amylase activity in mice that were administered with two of the drugs vs mice administered saline. However, administration of the third to animals on normal diet led to a 1.4-fold increase in amylase activity (p≤0.01, n = 3 per group) and a 1.3- fold increase in mice on a high fat diet (p≤0.01, n = 4 per group).
