demonstrate dialysis tubing we used water‚ starch and iodine. When starch and iodine react together they form a dark brown color. Materials Rubber band Dialysis bag Beaker Glucose solution Iodine solution Water‚ thread Methods Cut a piece of dialysis tubing that has been soaking in water approximately 40 cm (approx. 16 in) long‚ Tie the end of the dialysis tubing with two or more knots. Fill the bag halfway with glucose solution. And add 4 full droppers of starch solution to the bag. Hold the open

affect the activity of the Amylase? Abstract: In my experiment I aimed to observe how ranging pH levels will affect the rate in which amylase will break down the starch molecules. I will be measuring the time it takes for the dark liquid to disappear and leave a yellow brown liquid to be shown‚ which would show that there is no starch present in the solution because it would have broken into maltose by adding amylase. Results did not fully demonstrate what we expected in our hypothesis‚ but did

reagents to test to determine the presence of macromolecules: Benidicts solution for sugar‚ Iodine for starch‚ Biurets reagent for protein‚ and Sudan III for lipids. Hypothesis (1 point) If we test buttermilk biscuits for starches‚ sugars‚ proteins and lipids then it will test positive for all. If we test potato chips for starches‚ sugars‚ proteins and lipids it will then test positive for lipids and starch. If we test peppers for starches‚ sugars‚ proteins and lipids then it will test positive for only

rows on the tile. * Label a test tube with the pH to be tested. * Use the syringe to place 2 cm3 of amylase into the test tube. * Add 1 cm3 of buffer solution to the test tube using a syringe. * Use another syringe to add 2 cm3 of starch to the amylase/ buffer solution. Start the stop clock and leave it on throughout the test. Mix using a plastic pipette. * After 10 seconds‚ use the plastic pipette to place one drop of the mixture on the first drop of iodine.

dairy and starch. However‚ I found the menu to not be very child friendly. If I were in charge of the menu I would offer a more child friendly menu to the children with items that they are more likely to eat while still keeping the meals healthy. I would add entrees such as spaghetti‚ macaroni and cheese‚ sandwiches and ravioli’s. I would also try and offer more common vegetables to the children like corn‚ green beans‚ broccoli and carrots. Another change I would make is to switch up the starch a little

2010 p.90). The purpose of the lab was to test how temperature will affect the rate at which starch hydrolyzed. In the experiment conducted‚ bacterium; Bacillus Licheniformis and the fungus; Aspergillus Oryzae was used to examine how changes in temperature of the enzymes affects the rate of the reaction with starch. Amylase is an enzyme‚ found chiefly in saliva and pancreatic fluid‚ that converts starch and glycogen into simple sugars. This enzymatic reaction therefore needs the utilization of water

Genetically modified corn‚ Gasoline and High fructose corn syrup Did you know that about 85% of our corn is genetically modified (True Food Network)? It’s really surprising how genetically modified food has been incorporated into our society. We eat genetically modified food every single day whether it would be yogurt‚ fruits‚ milk‚ peanut butter‚ etc. So what is genetically modified food‚ according to “Non-GMO shopping guide”‚ genetically modified food (also known as GMO) is define as “the result

The winged bean (Psophocarpus tetragonolobus) is a twining‚ perennial herbaceous legume which can climb to 3-4 meters (Kantha and Erdman‚ 1985). As a leguminous plant‚ winged bean can be used in almost all parts of the plant. Fruit‚ leaves‚ flowers‚ bulbs and seed are edible and contain high protein and oil (Kotaru et al.‚ 1987; Dwiani et al.‚ 2014). The mature‚ dry seed is the most nutritious part of the winged bean. Their outstanding nutritive quality is based‚ above all‚ on their high protein
