What are the uses of starch and iodine solutions in the determination of amylase activity?
Starch solution is used as a substrate to test for the presence of amylase enzyme activity. When amylase breaks down starch, it produces smaller sugars that can be detected using iodine solution. Iodine reacts with starch to form a blue-black color, allowing the visual detection of the breakdown of starch by amylase.
What will happen if you add some amylase to a starch solution and test it after 5 minutes?
The amylase enzyme will break down the starch molecules into smaller sugar molecules such as maltose. Testing the solution after 5 minutes will likely show a decrease in starch concentration and an increase in sugar concentration.
What enzyme dissolves starch?
Amylase is the enzyme that breaks down starch into maltose, a type of sugar. It is found in saliva in the mouth and in the pancreas.
Is amylase a protein?
Yes, amylase is a protein.
Does salivary amylase contain sodium hydroxide or sodium carbonate?
No, absolutely not, it will not 'work' in alkaline (basic) solution. Salivary amylase (ptyalin) inactivates rapidly outside of its optimum pH 5.6-6.9
What is the theoretical achromatic point of salivary amylase?
If we add salivary amylase to any solution ( eg:iodine solution) the colour of solution changes to blue.THE TIME TAKEN BY THE SALIVARY AMYLASE TO CHANGE ITS(iodine solution) COLOUR TO BLUE IS CALLED ACROMATIC POINT OF SALIVARY AMYLASE. ie, the time upto which the solution is colourless and after that it gains blue colour.
What compound is produced as a result of mixing amylase with an aqueous solution of starch?
Maltose. Water and Starch mixed with amylase makes maltose

Which enzyme is found in the saliva and which food type does it act on?
The enzyme found in saliva is called salivary amylase. It acts on carbohydrates, specifically breaking down starch into simpler sugars like maltose.
What would be the result of Benedict's solution on boiled amylase?
Because amylase, being an enzyme, is a protein, these molecules will not give a positive result in testing with Benedict's solution. This reagent is devised for testing sugar solutions (like sucrose), which MAY be formed at the amylolytic breakdown of starch (amylose, amylopectin). This breakdown can NOT occur when boiled enzym molecules are used (because of inactivation by denaturation of the protein structures).
What will happen if you add some amylase to a starch solution and test it after 5 minutes?
The amylase enzyme will break down the starch molecules into smaller sugar molecules such as maltose. Testing the solution after 5 minutes will likely show a decrease in starch concentration and an increase in sugar concentration.
What conclusion can be drawn from the experiment when amylase and maltase were added to a maltose solution?
Maltase digests only maltose
How to undertake Phadebas amylase test?
To conduct the Phadebas amylase test, first, take a fecal sample and place it in a tube. Add Phadebas reagent to the tube and incubate it for a specific amount of time. Then, measure the absorbance of the solution at a certain wavelength to quantify the amylase activity in the sample.
Pancreas?
amylase and lipase....majority is exocrine with tiny endocrine pockets....also secretes an alkaline solution of bicarbonate into duodenum....
Would amylase be active in the stomach?
Salivary amylase works well around pH 7 (inside the mouth), but inside the stomach are gastric juices which contain HCl. Since the HCl drops the pH of the solution significantly, it denatures the amylase so that it will no longer function as it normally would, breaking down starch and glycogen.
Is ptylin an alpha amylase or beta amylase?
Ptyalin is an alpha-amylase. It is the alpha-amylase found in saliva
How many kinds of amylase?
There are three main types of amylase: salivary amylase, pancreatic amylase, and fungal amylase. Salivary amylase is produced in the mouth, while pancreatic amylase is produced in the pancreas. Fungal amylase is produced by fungi and is often used in commercial applications such as in the food industry.
