9000-90-2 Usage
Uses
Used in Ethanol Production:
Alpha-Amylase is used as a catalyst in the production of ethanol, breaking starches in grains into fermentable sugars, which can then be converted into biofuel.
Used in High-Fructose Corn Syrup Production:
In the food industry, alpha-Amylase is used as a catalyst during the production of high-fructose corn syrup, where it helps break down starches into simpler sugars.
Used in Detergent Formulation:
Alpha-Amylase is used as an active ingredient in some dishwashing and starch-removing detergents, helping to break down and remove starch-based stains.
Used in Biomedical Research:
Alpha-Amylase from Bacillus sp. is used as a dispersal enzyme to test the degradation of S. aureus biofilms, as well as in the enzymatic hydrolysis of tapioca starch and the enzymolysis of plant-based native and amorphous granular starches.
Used in Plant Metabolism Studies:
Alpha-Amylase has been utilized in various plant studies, such as metabolism studies in Arabidopsis, to better understand the role of this enzyme in plant processes.
Used in Enzymatic Assay Interference Testing:
Alpha-Amylase from human pancreas has been used to test interference for enzymatic methods of assaying calcium in serum and urine, providing insights into the potential impact of this enzyme on diagnostic tests.
Used in Automated Amylase Detection System Evaluation:
Alpha-Amylase, from Sigma, has been used to create a standard calibration curve during the evaluation of an automated amylase detection system using forensic samples, ensuring accurate and reliable results.
Used in Nutraceutical Development:
Alpha-Amylase from human saliva has been used in the development of nutraceuticals, which may aid in the treatment of diabetes and obesity by influencing the breakdown and absorption of carbohydrates.

Biotechnological Production
a-Amylases (4-a-D-glucan glucanohydrolase, EC 3.2.1.1) degrade starch and
similar carbohydrates by endohydrolysis of their (1→4)-a-D-glucosidic bonds. The
majority of a-amylases belong to the group of metalloenzymes and require calcium
ions (Ca2+). By means of direct evolution, the performance of several
amylases was further maximized and adapted to the needs of the starch processing
industry. The enhancement of the thermostability of amylase was achieved by
DNA-shuffling techniques. The baking industry and consumers might benefit
from genetically optimized starch-modifying enzymes. Based on the improved
thermal stability of an a-amylase in the acidic pH range, the retrogradation of
sourdough breads ("staling") can be delayed.
Biochem/physiol Actions
α-amylase catalyses the hydrolysis of α-1,4 glycosidic linkage in oligosaccharides. It plays a crucial role in the initial digestion of starch, glycogen and polysaccharides. Elevated levels of amylase in serum is linked to acute pancreatitis.
Check Digit Verification of cas no
The CAS Registry Mumber 9000-90-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 9000-90:
(6*9)+(5*0)+(4*0)+(3*0)+(2*9)+(1*0)=72
72 % 10 = 2
So 9000-90-2 is a valid CAS Registry Number.
