The dialysis tubing is made up of cellulose fibers. This is shaped in a flat tube. In this experiment, the selective permeability of dialysis tubing to glucose, starch and iodine (potassium iodide) will be tested. This experiment consists of two tests; the test for starch and the test for reducing sugar. When iodine (potassium iodide) is added ...

Resistant starch is a carbohydrate that resist digestion in the small intestine and ferments in the large intestine. As the fibers ferment they act as a prebiotic and feed the good bacteria in the gut. There are several types of resistant starch. They are classified by their structure or source.

Wolves do not eat a diet with high amounts of starch, but do ingest some in the wild fruit they sometimes consume (e.g. berries). In order to benefit from starch, mammals use a class of enzymes called amylases that break the starch chain down into separate glucose molecules. In wolves, amylase is produced in the pancreas.

Looking at digestion of starch we used the enzyme amylase, both test tubes contained starch and iodine however the test tube containing amylase became clear after heating. Based off the test tube turning clear we know the starch had been broken down. When Benedict solution was added it caused a precipitate to form,
