What inhibits alpha-amylase?
Dietary phytic acid may have health-promoting properties. It can inhibit α-amylase, limit carbohydrate digestion, and lower blood glucose.
How does acid affect amylase?
Gastric acid in the stomach inactivates α-amylase but as the bolus of food takes time to disintegrate in the stomach, salivary digestion can continue within it for as long as half an hour. When the acid has completely penetrated the food the enzyme is inactivated. α-Amylase works best at a slightly alkaline pH.
Why is amylase used in detergents?
Proteases, lipases, amylases, and cellulases are enzymes used in detergent formulation to improve the detergency. The amylases are specifically supplemented to the detergent to digest starchy stains. Most of the solid and liquid detergents that are currently manufactured contain alkaline enzymes.
What does sodium chloride do to amylase?
At temperatures near and above the optimum for salivary amylase activity an increase in sodium chloride concentration from 4 × 10−3, N to 4 × 10−2, N increases amylase activity and, at temperatures above the optimum, slows the decrease in activity which accompanies an increase in temperature.
What is alpha-amylase used for?
Starch Conversion The most widespread applications of alpha amylases are in the starch industry, which is used for starch hydrolysis in the starch liquefaction process that converts starch into fructose and glucose syrups.
Why does pH affect amylase?
Above pH 7, the activity of amylase rapidly decreases beacuse the concentration of H+ ions (or protons) is too low. This change in [H+] alters the interactions between the variable R-groups of the amino acids in the protein chains that make up the enzyme.
How amylase is affected by pH?
The optimum pH for the reaction of starch with amylase is pH 7. PH values lower or higher than this value will result in a slower rate of reaction. Amylase works in the range pH 3 to pH 11. PH changes affect the structure of an enzyme molecule and therefore affect its ability to bind with its substrate molecules.
What is the difference between Alpha Beta and Gamma amylase?
The key difference between alpha beta and gamma amylase is that alpha amylase enzyme works by acting on random locations along the starch chain and beta amylase works from the non-reducing end of the polysaccharide by cleaving alpha-1,4 glycosidic bonds, whereas gamma amylase works from the non-reducing end of the …
How can you tell the difference between alpha and beta amylase?
Alpha Amylase: α-amylase is insensitive to high temperatures and heavy metal ions and is inactivated at a low pH. Beta Amylase: β-amylase is sensitive to high temperatures and heavy metal ions, and is stable at a low pH. In conclusion, amylase is an enzyme that can hydrolyze starch into smaller molecules.
What stains does amylase remove?
How amylases break down starch stains. Starch molecules are formed of long chains of sugars, making them difficult for detergents to remove. That’s why stains containing starch are so stubborn. Amylase enzymes cut the starch molecules into tiny sugars that are lifted off the fabric in the wash more easily.
Why oxylife crème bleach?

Where can I buy oxygen bleach?
Natural Choices also carries several other sodium percarbonate based products including dishwashing, toilet bowl cleaner, kitchen and bathroom cleanser and laundry detergent (See below). They have the most complete line of oxygen bleach products available anywhere and are probably the most knowledgeable on their use.
What does it mean when your serum amylase is high?
The serum amylase concentration reflects the balance between the rates of amylase entry into and removal from the blood. Hyperamylasemia can result either from an increased rate of entry of amylase into the circulation and/or a decreased metabolic clearance of this enzyme. The pancreas and salivary …
What is an amylase test?
An Amylase test can be a blood test and/or a urine test and helps to measure the amylase levels in the blood or urine. An Amylase blood test helps to diagnose if there is any problem or inflammation with the pancreas, pancreatitis, or any other medical condition.
