Introduction The idea of the experiment was devised due to having recent interest of Vitamin C in food contents. My family tends to have fruits and vegetables stored in the freezer. This is due to the hot climate of the country we live in. Therefore, it preserved it for a long period of time and then re-heated in order to be consumed. I began to wonder if change was happening to the Vitamin C in the fruits and vegetables once they were frozen. If so, then what? In class many lab experiments were performed such as ‘The Effect of Temperature on the Vitamin C Clock’, and observing many variables such as temperature, time and the amount of Ascorbic Acid (Vitamin C) poured into the solution. The experiment was shown to be a great interest to me …show more content…
Vitamin C is sensitive to temperature (presence of heat), exposure to light and exposure to air (oxygen). It is considered ‘the most easily destroyed vitamin’. [4] Hypothesis: If the Vitamin C is to be frozen and thawed then the molecules will be destroyed, thus decreasing the concentration of the substance. According to the experiment, the main factor that will have to be taken into account of when freezing, will be the blanching process. This process destroys about 25% of the Vitamin C prior to the substance becoming frozen. [2] Methodology Chemical Reaction There is a method to indicate the amount of Vitamin C in a solution by a redox titration reaction using iodine. The iodine would be added during the titration, the ascorbic acid would become oxidised to dehydroascorbic acid (a colourless chemical), and the iodine would be reduced to iodide ions. [6] This is because ascorbic acid loses the hydrogen atoms (2) to the iodine and dehydroascorbic acid is formed. [4] The acid itself is a powerful anti-oxidant and a reducing agent that is capable of donating one to two electrons in redox reactions. [3] The equation for the reaction
C4564 Description: IC50: 3-AP is a ribonucleotide reductase inhibitor and iron chelator with antitumor activity. Ribonucleotide reductase, the rate-limiting enzyme for de novo DNA synthesis, is an excellent target for chemotherapy. Its increased activity in cancer cells is associated with malignant transformation and proliferation.
How Temperature Effects the Catalytic Ability of Peroxidase from Potatoes Abstract In order to determine if temperature affects the ability of Peroxidase to react, we measured the reaction rate of the same solution exposed to different temperatures. Solutions were exposed to a 4-degree, 22-degree, 32-degree, or 60-degree Celsius environment then measured by a spectrophotometer. The solution left in the 22-degree environment had the highest reaction rate, while the solution exposed to the 60-degree water bath was not able to react at all.
Medical biller is a position that will require you to take in medical claims and code them and bill out medical claims to insurance companies, Medicare and Medicaid on a daily basis. You will have to reconcile Explanation of Benefits (EOB) weekly. Verify if insurance companies require that patients get PA for certain procedure and products. Five requirements for Medical Biller position 1. How to bill claims 2.
These reactions, in turn, depend upon specific vitamins to help catalyze, or facilitate, their actions. Without these vitamins, nothing happens. Even if only one of
In recent research studies, the healing properties of oranges have been associated with a wide variety of phytonutrient compounds. these phytonutrients include citrus flavanones when it's combined with vitamin c the antioxidant properties are expected to be there but it's another molecule that makes the vitamin c stronges and it is the hesperidin molecule which has been singled out as the most important
ABSTRACT Due to the potential harmful effects of the glacial acetic acid, a commonly used diluting fluid for manual WBC count, the researchers proposed to use commercially-prepared ascorbic acid to lyse the red blood cells while maintaining the morphology of the white blood cells. This study aimed to compare the capability of commercially-prepared ascorbic acid as a lysing agent in a diluting fluid to glacial acetic acid. Specifically, this study aimed to compare their capabilities in lysing red blood cells, maintaining white blood cell morphology and white blood cell count.
There are two types of vitamins: water soluble and fat soluble. Water soluble vitamins include vitaminsB1, B2, B3, B6, B12, vitamin C, biotin and folate. They are not stored in large amounts in the body, andany extra is lost through your urine says the Dietitians of Canada web page. Vitamin B1 helps with energy production in the body. Vitamin B2 helps with energy production in thebody.
The article, "Vitamin A", is written by Susan Sullivan, who is the associate director of the University of Maine. Vitamin A is a major nutrient associated with healthy skin and eyes, growth, and immune system function. It is essential for reproduction and the growth of children. Ms. Sullivan writes about the different forms, symptoms of deficiency, toxicity, and the history of vitamin A. The article main purpose is to provide information on the importance of vitamin A to your body if you follow the United States National Academy of Medicine's recommendation of dietary allowance.
In this experiment I will be testing the effect that different solutions (oil, soap, alcohol, salt and sugar will have on the membrane of cherries. In plant cells one type of membrane bound vacuole is the tonoplast ( it is quiet large and contains water). However in cherries this vacuole also contains a water soluble red pigment called anthocyanin . The anthocyanin gives the cherry it’s red colour. When the membrane of a cherry is damaged the colour will fill the surrounding environment.
Home Remedy Bone & Joint Pain of Bodybuilders: Omega-3 Fats A substantial amount of research suggests that all player, bodybuilder should use during their daily workouts omega-3 fatty acids may prevent inflammation in the body and reduce symptoms associated with arthritis. Researchers from the Center for Genetics, Nutrition and Health have discovered that the COX-2 enzymes that cause joint inflammation are more active when you eat a high ratio of omega-6 to omega-3 fatty acids. Omega-6 fats are prevalent in the diet, found in meat, corn, snack foods, and sunflower oil. Try reducing your intake of these fats while increasing your consumption of healthy omega-3 fats, which are found in salmon, sardines, mackerel, trout, flaxseeds and walnuts.
A few situations can trigger the thirst mechanisms, such as consuming high amounts of salty products and low amounts of water. An overconsumption of salty products increase the blood sodium level which eventually signals the body to drink water. Also, inadequate levels of body fluid can cause the mouth to experience a dry sensation because its tissues’ are only exposed to a limited supply of fluid. Lastly, blood loss, sweating, and diarrhea can also signal the body to increase fluid intake through monitoring the levels of blood pressure and blood volume. Water intake varies among individuals and is influenced by their level of physical activity and the type of environment they live in.
Experiment #7: Column Chromatography of Food Dye Arianne Jan D. Tuozo Mr. Carlos Edward B. Santos October 12, 2015 Abstract Column chromatography is the separation of mixture’s components through a column. Before proceeding with the column chromatography itself, a proper solvent system must be chosen among the different solvents. The green colored food dye is the mixture whose components are separated.
How Much Cranberry? Most people are overweight. Many doctors and medical practitioners recommend between 1 and 10 oz of pure rubric per day for this UTI treatment. We have obtained a lot of 6 oz, or less than a juice glass, and divide it between three times a day.
Abstract The unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20◦C and 30◦C). With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.
Process of vitamin D deficiency treatment Vitamin D is not a true vitamin, as individuals with adequate exposure to sunlight do not require dietary supplementation. Vitamin D is present in our bodies in two forms Cholecalciferol and ergosterol. Vitamin D3, cholecalciferol is generated in the skin of animals when light energy is absorbed by a precursor molecule 7-dehydrocholesterol. It does not have significant biological activity until it should be metabolized within the body to the active form of the hormone called 1, 25-dihydroxycholecalciferol in both the liver and Kidney.
