digests the starch‚ what results would you expect? If the amylase successfully digests the starch‚ I would expect a no color change occur as well as a presence of glucose in the intestine (Dialysis tubing). If the amylase only partly digests the starch‚ what would you expect to happen? If the amylase only partly digests the starch‚ I would expect to see a faint color change as well as a small presence of glucose inside the intestine. If the amylase fails to digest the starch‚ what results

Dark Purple Proteins are present with purple peptides 3 Pepsin Purplish blue‚ darkish blue Proteins are present with purple or black colored peptides 4 Starch Light blue‚ really clear Possible little protein with clear peptide or no protein at all Our results are correct because water and starch should not contain protein (starch is a polysaccharide but not of an amino acid) and therefore remained blue unlike Albumin and Pepsin which do contain proteins causing them to turn into a different

added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.) Beakers 3.) Test tubes 4.) Water bath 5.) Iodine solution 6.) Starch solution 7.) String x4 8.) Dropper 9.) Thermometer 10.) Salty water

by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for the Dye test was to test for lipids. When mixed with water and the tested substance‚ a positive result will occur in it being separated from the water. The

QUESTIONS 1. What are other sources of glycogen? Of starch? a. Other sources of glycogen- Aside from the liver‚ it can also be found in skeletal muscles (for energy during strenuous exercise). It also occurs in tissues including adipose tissues‚ heart muscles‚ kidneys and the brain. It is also found in yeast‚ bacteria‚ fungi‚ molds and algae‚ oysters‚ and shellfish. b. Other sources of starch- Foods that are high in starch include breads‚ grains‚ cereals‚ pasta‚ rice‚ potatoes‚ peas

Hydrolysis Report Bile Esculin Hydrolysis‚ Starch Hydrolysis‚ UreaHydrolysis‚ Casein Hydrolysis Hydrolysis Report Introduction Hydrolysis is a chemical reaction that uses water to split complex molecules. The water molecule H2O is split in the mechanism of hydrolysis‚ hydrogen cations and hydroxide anions. When the enzyme catalyzes its reaction inside the cell‚ it is referred to as intracellular hydrolases. When the enzymes secreted from the organism to catalyze reactions outside the cell‚ it

A cellophane dialysis tube (1.6 cm diameter‚ 2.0 mL/cm‚ MW cut-off:12000-14000) was clipped on both ends and filled with 10 mL of a starch‚ glucose solution after being soaked in water for 5 minutes to remove any storage additives. The dialysis tube was placed within a 200mL beaker filled with distilled
