Vitamin C, also known as ascorbic acid, is a water-soluble nutrient that is essential for the proper functioning of the human body. It is found in a variety of fruits and vegetables, and it is known for its ability to support the immune system and promote healthy skin. In this essay, we will explore the science behind vitamin C and discuss how it can be studied in a science project.
One of the primary functions of vitamin C is to support the immune system. It helps to protect the body from infections by supporting the production of white blood cells, which fight off invading bacteria and viruses. Vitamin C is also an antioxidant, which means it can help to protect cells from damage caused by free radicals. Free radicals are unstable molecules that can damage DNA and other cellular components, leading to inflammation and disease. By neutralizing these free radicals, vitamin C can help to reduce the risk of certain types of cancer and other degenerative diseases.
In addition to its immune-boosting and antioxidant properties, vitamin C is also important for the synthesis of collagen, a protein that is found in the skin and other connective tissues. Collagen helps to maintain the elasticity and strength of these tissues, and vitamin C is necessary for its production. As a result, vitamin C is often used in skin care products to promote healthy, youthful-looking skin.
There are many ways that vitamin C can be studied in a science project. For example, you could explore the effect of vitamin C on the growth of plants. To do this, you could set up a controlled experiment in which you grow a group of plants with different levels of vitamin C in their soil. You could then measure the growth of the plants over time and compare the results. This could help you to understand how vitamin C affects plant growth and development.
Another idea for a science project on vitamin C could be to investigate the effect of different storage conditions on the stability of the nutrient. You could set up a controlled experiment in which you store samples of vitamin C in different conditions (e.g., at room temperature, in the refrigerator, or in the freezer) and measure the concentration of vitamin C in the samples over time. This could help you to understand how different storage conditions can affect the stability of vitamin C and how to best preserve the nutrient.
In conclusion, vitamin C is an essential nutrient that plays a number of important roles in the human body. It supports the immune system, acts as an antioxidant, and is necessary for the synthesis of collagen. There are many ways that vitamin C can be studied in a science project, including exploring its effects on plant growth and investigating the stability of the nutrient under different storage conditions. By studying vitamin C, we can learn more about this important nutrient and its role in maintaining good health.

Effect of vitamin C on common cold: Randomized controlled trial. Be sure to swirl the solution to rinse all surfaces. Filter the starch solution through 2 to 4 of the thicker brand paper coffee filters until you have a clear liquid. There are no reliable functional tests for vitamin C status. There has been much controversy over speculation that Vitamin C intake should be much higher than the RDA for the prevention of colds and flu. It will allow you to measure the amount of vitamin C in any other mixture if you use the same Iodine solution and the same eye dropper.
When printing this document, you may NOT modify it in any way. To determine the concentration of a substance in a solution, chemists use the technique called titration. You should get results that are within about 0. Simon brings her passion for working with organizations dedicated to improving the quality and delivery of healthcare. Vitamin C in the critically ill — indications and controversies. Pneumonia leads to reduced vitamin C levels as measured in leukocyte immune cells, plasma and urine Hemilä, 2006. Without a control you cannot be sure that changing the variable causes your observations.

Mix 2 tablespoons of cornstarch in 500 ml of water to make a cornstarch solution. This desire stems from her years of practice as a licensed naturopathic physician. Vitamin C may reduce the duration of mechanical ventilation in critically ill patients: a meta-regression analysis. You should rinse the buret first with deionized water, and then twice with approximately 10-mL aliquots of the solution you will be using in the buret. Vitamin C and common cold incidence: a review of studies with subjects under heavy physical stress. In a recent study, the mean concentration of ascorbate in the human vitreous gel was found to be approximately 2mM. If it comes from a product label please remove the label and attach it to this report.

The brand has since expanded to include additional oils, green food concentrates and other premium supplements. He is committed to improving the quality of life for every person on the planet by making the best products and by using the profits to support outreach programs. Linus Pauling, winner of both a Nobel Prize in Chemistry and the Nobel Peace Prize, has argued in his book, Vitamin C and the Common Cold, that humans should be consuming around 500 mg of Vitamin C a day considered by many doctors to be an excessive amount to help ward off the common cold and prevent cancer. Diagnosis and management of glucose-6-phosphate dehydrogenase G6PD deficiency. Careers If you like this project, you might enjoy exploring these related careers: There is a fraction of the world's population that doesn't have enough to eat or doesn't have access to food that is nutritionally rich. Vitamin C uses Fe++ and Cu++ as cofactors, and it enhances intestinal Fe++ absorption.
The procedure for the titration was carried out using the following steps. Glial cells in the brain regenerate vitamin C from DHA. This author has pointed out that a reason for mixed and negative results for vitamin C and prevention of colds can be too low of dosing the vitamin. That would be like comparing oral Benadryl diphenhydramine to intravenous, or oral steroids to injected ones; they do not produce the same results. When vitamin C is added, it becomes colorless.
Phase I clinical trial to evaluate the safety, tolerability, and pharmacokinetics of high-dose intravenous ascorbic acid in patients with advanced cancer. As an ICU stay is highly costly to the hospital and patient — not to mention beds may be in short supply — even a moderate reduction in length of stay is worth exploring, especially when the treatment in question is relatively low in cost and can significantly impact mortality. Juice extractors used to make carrot juice or apple juice may be used for vegetables too. Use the instruction manual as you experiment, and take a look at the include prompts inside for some science fair project inspiration! Good Question I'm at Experimental Procedure step 7, "Move the magnet back and forth. Bad Question Can I use a different part? Have you ever wondered why some foods taste really sour? Some of them are more stable and others are easily destroyed by UV radiation from the sun light. The instant cold packs are not pre-cooled—you just squeeze the cold pack and its starts to get cold. Students can evaluate these phenomena using a starch and iodine solution.
Iodine and Vitamin C Experiment (magic disappearing color experiment!)
Other single-electron reductants can substitute for ascorbate to provide reducing equivalents for Cu 2+; consistent with this, no ascorbate-specific binding site has been identified on PHM. It is an antioxidant because it can donate electrons to decrease reactive oxygen species ROS in the body. School Name: Monzano Day School Grade: Fourth Teacher: Heather Behling How did I get interested in the project? In the end of this article you'll find some ideas for vitamin C science projects which you can do using this method. As Vitamin C and other nutrient-based therapies are within the toolkit and expertise of naturopathic medicine, the INM has provided an outlet to disseminate basic science information on this intervention. This means that "Iodine 2" equals 6. Ascorbate provides an aqueous phase antioxidant capability to complement the lipophilic antioxidant capacities of α-tocopherol and related species. Your results should be accurate to at least three significant figures.
And finally, I made a control sample of Vitamin C tablet solution to determine whether a weaker or stronger concentration of vitamin C was present in each fruit and vegetable juice tested. Fresh fruits and vegetables are the main source of vitamin C, but how to find out if we are having enough? Two molecules of ascorbate are used by APX for reduction of H 2O 2 to H 2O. This can be anywhere from 0. When we administer a medication by IV dosing, we bypass the gut.
