Glucose tolerance test

Firstly, During the procedure the purpose of this lab was to determine and identify if there is protein in water, apple juice, vegetable oil, potato, and egg whites. This was done by using the biuret solution. So this means if the material turns purple then we know it contains the protein, but if it doesn't turn out to be purple then it doesn't contain protein. The data in this experiment shows that water, apple juice, vegetable oil, and potato all did not contain protein this is because none of…

the foods consumed such as sugars,carbs, proteins, and other foods ranked on the Glycemic Index. The glycemic index (gi) rates food on a scale of how quickly glucose is released into the body (Brand-MIller, 2014). Foods high on the gi quickly release glucose into the body, while foods low on the gi slowly release sugars over time. When glucose is quickly released into the body a quick “energy burst” occurs (Clarke, 2014). After this “energy burst” would come come a crash leaving one’s energy…

Insulin is the most important regulatory hormone in nutrient homeostasis. It was first isolated from pancreatic tissue in 1921 by Banting and Best. Appropriate target tissue responses to insulin added to insulin synthesis and secretion are necessary to maintain normal fuel balance (Lebovitz, 2001). Biochemistry: Figure: Human proinsulin and insulin biochemistry, Junqueira et al., 1986 Insulin is a protein consisting of 51 amino acids contained within two peptide chains. A chain with 21…

on performance in athletes versus nonathletes during strenuous exercise the Wingate Anaerobic Test was performed on nonathletes. The Wingate Test allowed for the examination of performances during short-term maximal exercise and maximal lactic anaerobic capacity investigation. The test consisted of 30s period of supramaximal cycling against a resistance determined relative to each subject’s weight. The test examined three reproducible indices of work, the maximal anaerobic capacity (AC),…

ketoacidosis involve a shift in the intracellular and extracellular levels. It usually happens in patient with Type I diabetes. At the beginning there is an insufficient supply of insulin circulating which will lead to a higher glucose levels that cause osmotic diuresis. As a result, glucose is permeable to the glomerular filtration (glycosuria) and is excreted in the urine. Furthermore, sodium, potassium, magnesium, calcium and phosphorus are lost because of the osmotic diuresis and glycosuria.…

Insulin, one of the most important peptide hormone in the body, which plays significant role in maintaining the blood glucose level in the body. Under certain physiological conditions such as pregnancy, the body mechanism changes due to elevated levels of certain secretory factor like leptin, plasminogen activator inhibitor-1, TNF-α, plasminogen activator and testosterone (McLachlan et al., 2006), which produces certain adverse effects, insulin resistance being the most prominent one, where the…

I expected that pepsin will destroy the structure of gelatin protein, because the pepsin broke down the primary structure of the gelatin polypeptide into amino acid monomers. The hydrochloric acid (HCL) expected to affect the ability of amylase to digest starch, because as it is an acid it effects on the protein that makes it unraveled as it breaks down the secondary structure which it contains hydrogen bonds. As I have done to experiment one titled Digestion of Proteins by Pepsin. The result…

been experiencing the previous weeks returned with a vengeance. Realizing something to be amiss, my mother drove us to the nearest medical clinic. A nurse eventually pricked my finger to test my blood and revealed a glucose level above 700 mg/dl. After receiving my first insulin shot, she explained that a normal glucose reading should be between 80-120 mg/dl and that as a new Type 1 diabetic, I would need to make fundamental lifestyle changes. This disease is incurable, but ultimately manageable…

The purpose of the Benedict’s test was to identify if the food samples and unknowns contained simple sugars. In the sugar, is a ketone or an aldehyde which will reduce copper (II) ions to copper (I) ions (Areda, 2017). This must be done by heating the food sample and Benedict’s solution. The copper will be oxidized resulting in a brown-orange color (Areda, 2017). Thus, if a sample is positive for simple sugars the color will change from a light blue to colors of green, yellow, orange, brown or…

Glucose is a monosaccharide which is a simple sugar make up of a single chain or ring of carbon atoms with hydroxyl groups attached. Their carbonyl group is what distinguishes them. It has a sweet taste and is soluble in water. A nitrogen atom is present in amino acids but not in sugar molecules Elements found in lipids are hydrogen, oxygen, and carbon. Purpose The purpose in this lab is to determine the presence of certain macromolecules made by cells by detecting carbohydrates, lipids and…
