To test starch:

To test starch you take the food sample, and add iodine solution if the colour turns black this means starch is present.

To test for protein:

To test for protein, you take the food sample and add Biuret A and Biuret B and shake, if the colour turns lilac this means that protein is present.

What part of the alimentary canal is starch digested?

Salivary amylase in the mouth starts some of the breakdown. Further breakdown occurs in the small intestine where the remaining starch is acted upon by pancreatic amylase.

What is the substrate for pancreatic amylase?

The substrate for pancreatic amylase is starch. Amylase breaks down starch into maltose, a disaccharide composed of two glucose molecules. This breakdown process is important for the digestion and absorption of carbohydrates in the small intestine.

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 part of the body has enzymes that begins the process of breaking down starch molecules?

The salivary glands have an enzyme called amylase that begins the breakdown of starch.


What is the enzyme that digests starch?

The enzyme that digests starch is called amylase. Amylase is produced in both the saliva (salivary amylase) and the pancreas (pancreatic amylase) and breaks down starch into smaller sugar molecules like maltose.
