2.4 Dietetic management 2.4.1 Calories A calorie is the unit used to measure the energy-producing value of food. Theoretically, calorie is characterizes as a unit of heat measurement, in nutrition and the kilocalorie is the amount of heat required to raise the temperature of 1kg water through 1˚c. Another definition is that calorie is a unit of measurement that determines the amount of heat released in a food during metabolism. It states the energy value of a food calorie (cal) or kilocalories…

T4. Hyperthyroidism can be caused due to many conditions likes grave’s disease an autoimmune disorder, producing antibodies to excite thyroid gland to produce excess hormone, and causing inflammation of thyroid Gland. Drug induced, excess intake of iodine…

In experiment 1.1, we studied the relationship molecule size has with diffusion rate. Our hypothesis claimed that smaller molecules will travel farther across the agar plate given the same duration of time. Based on the data collected, our hypothesis was proven true. Potassium permanganate has a molar mass of 158 g/mol, methylene blue 319.85 g/mol, and potassium dichromate with 294.185 g/mol. Potassium permanganate diffused the farthest, potassium dichromate second, and methylene blue secured…

The aim of this study was to investigate the optimal temperature for α-Amylase to catalyse the hydrolysis of starch. After the implementation of the experiment, it was established that the hypothesis, that the ability of α-Amylase to act upon large linear carbohydrate polymers in starch will prove most effective at 37°C (the optimum human body temperature), was supported by the observed data. The hypothesis was justified based on the observation that the overall average of average colour…

hydrolysis of starch to be 60°C. This is against the hypothesis and internet statistics. Fig 1.1 shows that by the 1-minute mark, there was no traces of starch in the starch-iodine solution sample on the colour tiles (scale of 13); all of the starch solution was hydrolysed in the first minute. At the time-0 mark, the starch-iodine solution was already at a scale of 8. This means that in the split second of time between adding the amylase to the starch solution and stirring it with the pipette to…

test tube 6 was added into row B, one drop of test tube 7 was added into raw C, and lastly one drop of test tube 8 was added into raw D. Afterwards, directly add one drop of iodine to column 1 and observe the results after 5 minutes, then add another drop of iodine to column 2, and wait another 5 minutes. Continue to add the iodine to all columns with 5 minutes pause. The observations had been recorded by writing 1 when the color turned blue-black, and 2 when the color didn’t change and remained…

macromolecules made by cells by detecting carbohydrates, lipids and proteins with four different indicators. Materials Test tubes Test tube rack Benedict's solution Iodine Biuret reagent White paper Hot water bath Vegetable oil Glucose Sucrose Starch Protein Distilled water Post-lab questions A positive test for starch would be with iodine, because the starch turned black and opaque after the test and is the only substance out of the six to drastically change colour. Also the starch did not…

Those risk factors include, being a women, women in their 40’s/50’s, men in their 60’s/70’s, not enough iodine in your body, and exposure to radiation. There are several different ways you can go about diagnosing Thyroid cancer. One is just from medical history and a physical exam because like I mentioned earlier the disease can be genetic. The real diagnosis…

The purpose of this lab was to iodonize salicylamide and characterize the product in order to determine its structure. The crude product of this reaction was recrystallized using ethanol. The white crystalline product was isolated using vacuum filtration and characterized. The percent yield of this reaction was determined to be 39%. The observed experimental melting point of the product was determined to be 235-137 oC. When compared to the literature melting point 228 oC of the predicted product…
