Title Food Lab Abstract The aim of this report is to see if the any of the four food apple sauce‚ carrot juice‚ cracker juice‚ and turkey juice contain protein‚ starch‚ or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive for protein and

It was originally hypothesised that the reaction time would decrease with higher concentrations of the reactants‚ potassium iodate and sodium bisulfite as collision theory stated that more molecules present in a given volume meant a greater chance they would collide. Furthermore‚ the time was expected to decrease with higher temperatures as it influenced the reactant particles by raising their kinetic energy. However‚ the data collected from this experiment only partially supported this hypothesis

Title: Investigate the breakdown of starch at different temperature AIM This experiment has been done to investigate the action of the enzyme amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected

Using the Iodine clock method to find the order of a reaction Introduction When peroxodisulfate (VI) ions and iodide ions react together in solution they form sulfate (VI) ions and iodide. This reaction is shown below: S2O82-aq+ 2I-aq SO42-aq+ I2(aq) The reactants and the sulfate (VI) ions are colourless however the Iodine is a yellow/brown colour. This allows you to measure the progress of the reaction through the colour change when the iodine is produced. In order to determine the order of

Polymers can be made out of starch which is composed of long chains of glucose molecules. This study focuses mainly on making biodegradable plastics‚ which is certainly safer than non-biodegradable plastics‚ from potato starch. Biodegradable plastics made from raw materials are completely reusable and can be composted easily. Potato starch contains minimal protein and fat. Potato starch is a Polymer made of long chains of glucose units joined together. Potato starch contains two polymers: Amylopectin

materials. The core problem of these starch based plastics is their hydrophilic character and the fact that they tend to become brittle with ageing. Unmodified starch is too much hydrophilic to be used as food packaging material. Chemical modification must be carried out in order to make them hydrophobic. These modifications are grafting‚ alkylation-especially esterification including acetylation. The purpose of the project is to prepare acetylated starches/starch esters of different Degree of Substitution

Starch Diffusion in a Caterpillar’s Digestive Tract The object of this particular experiment is to gain knowledge on diffusion across a plasma membrane‚ which is selectively permeable. Diffusion is the movement of a substance from a region of high concentration to lower concentration. Experiment 2 was performed to see how the substance’s‚ starch‚ and diffusion process across a plasma membrane is affected by amylase. We prepared a simulated digestive tract of a caterpillar‚ as the plasma membrane

1. Cellulose‚ starch‚ and glycogen are very similar‚ yet very different. Describe the process by which each of these molecules is formed. Why does the subtle difference in how the simple sugar monomers are bonded in starch and cellulose affect how the two molecules are used? Cellulose is built from glucose molecules bonded covalently together through a process known as hydrolysis. Hydrolysis is a chemical process in which a molecule of water is added to a substance.
