Lab : Iodine-starch Clock Reaction Pre-lab: Before the lab was conducted‚ the concentration of the Iodate ions to be in the mixture made by dissolving specific volumes of solution A with a constant concentration and water was calculated using the dissolution formula: C1V1 = C2V2 Sample Calculation 1: Concentration of the Iodate ions: For mixture 1: C2 = C1V1/ V2 = (0.020mol/L) x (0.003L)/(0.01L) = 0.006mol/L The same calculations were used in the calculating of the

In October of 2015 I was appointed as the Peritoneal Dialysis Unit Coordinator. The peritoneal dialysis program was being developed at this time which created significant changes in the hemodialysis unit and for me. Change has always been stressful for me yet my Nurse Manager‚ with her endless support in managing this change made it a positive experience. I was ready to take on this change by taking on new roles and responsibilities‚ and adapting to implement the change fully and completely. Communication

Aldosterone and Hormone Replacement Therapy Aldosterone falls in the class of hormone called mineralocorticoids‚ produces by the adrenal glands and is found near the kidneys. It sustains blood pressure‚ water and salt balance within the body. This procedure is assisting the kidneys to preserve sodium and excrete potassium in order to maintain a balance. If Aldosterone production falls‚ there isn’t enough regulation of salt and water balance (as aldosterone is being lost through urination) triggering

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

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

CHEM 1021 BREAKING DOWN STARCH USING SALIVARY AMYLASE Caution: You will be using a Bunsen burner and glassware to create your own constant water bath. Appropriate caution should be exercised when dealing with the Bunsen burner‚ hot water‚ and glassware. Purpose: Many plants store their energy in the form of starch‚ a polysaccharide made from repeating units of the monosaccharide glucose. Our bodies break down starch into the individual glucose units

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

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. Each alternating glucose
