Analysis For Vitamin C

The mass percent of ascorbic acid in the sample is given by dividing the calculated mass of ascorbic acid (0.414060408 g) by the calculated mass of the sample (0.5500 g) and multiplying the quotient by 100%.

* Baby need Vitamin C is necessary for a normal growth and development immune function and help with iron.

In this experiment redox-based titrimetric analysis was used to determine the amount of ascorbic acid (Vitamin C) contained in a serving of lemonade. This was done to confirm the 100 percent recommended daily allowance claimed on the package for a serving of Country Time Lemonade. The titration method used was adding a thyodene indicator to the analyte (lemonade solution) there is a visible colour change when the endpoint of the reaction between the titrant (KIO3) and the analyte occurs. The following reactions show how this titration method is viable. (Draw in reactions) KIO3 first reduced with iodide (I-) to generate iodine (I2 ) which then oxidized the ascorbic acid within the lemonade. Once all the ascorbic acid had reacted any iodine

Vitamin A and D have showed unexpected and crucial effects on immune system. Vitamin A includes innate immune towards microbial infection, absence of vitamin A can increase the chance of bacterial, viral, and parasitic infection. Also excessive intake of vitamin A Is associated with toxicity, including blocked hematopoiesis, mitogen-induced T-cell spread, antigen-specific antibody production, and an increased susceptibility to infectious organisms. Vitamin A is also given by Retinoid supplement to treat the skin effects of T-cell lymphoma. Vitamin C also known as Ascorbic Acid also contribute in innate immunity system, Vitamin C works during infection to prevent oxidative damage. Lower concentration of vitamin C in leukocyte is related to reduce immune response in humans. It has been proven that Vitamin C concentrations in the plasma and leukocytes rapidly decline during infections and stress. Iron chelators such as desferrioxamine inhibit the activity of phagocyte oxidase and reduce reactive oxygen intermediate-dependent killing of bacterial pathogens, both in vitro and in vivo. Lastly, Zinc is a dietary trace mineral that is responsible for growth and development, and it is essential for the function of cells of the immune system. It increased susceptibility to

Water soluble vitamins are not stored in the body. They go directly to the blood stream once consumed, so they need to be replaced on a daily basis. B vitamins are important because they help turn food into energy. For example, niacin helps to release energy from carbohydrates, fats and protein. Many also act as coenzymes. Such as riboflavin, this is the coenzyme for the first reaction in the metabolism of glucose. Thiamin is also a coenzyme for tissue respiration. B vitamins and vitamin C are also essential for growth and development such as body tissue, the formation of collagen, development of red and white blood cells and the formation of DNA. When the

Based on the results of the test, the unknown substance was Calcium Chloride. Multiple tests were performed to determine the identity of the substance. By comparing known positive results to the unknown substance, properties could be discovered about the substance. Most tests led to this conclusion, however some tests did not follow the established properties of Calcium Chloride.

One milliliter of liquid was pipetted into three test tubes each making a total of nine test tubes. Biurets reagent, Lugol’s iodide, and Benedict’s solution were the reagents used to help identify the unknowns. One milliliter of each reagent was added to one protein test tube, one starch test tube, and one glucose test tube. We placed the test tubes with Benedict’s solution in a hot water bath for 5 minutes and recorded what happened. The three supplements acquired were tested using the same techniques used above and were compared to each other. The objective in this experiment was to determine what was in each

The Red #40 was mixed with 10 mL of DI water, the solvent. The volume of stock solution needed to prepare these solutions are shown in the second column of Table 3. After obtaining the appropriate micropipettor, 200 uL, it was used to measure the aliquot of the stock solution. This solution was transferred into a volumetric flask and diluted with the 10 mL of DI water. DI water was used as the blank and the solutions were then placed inside the cuvettes which were then placed into the Vernier pH spec-trophotometer. The absorbance and λmax of each solution were then recorded as seen in the third column of Table 2. These values were then plotted on a linear regression as seen in Figure 1. Next, 0.50 mL of maraschino cherry juice was obtained by using the appropriate micropipet-tor, 100 uL, of the aliquot of the stock solution. This was transferred into a volumetric flask and diluted with nanopure water until the solution reached 25 mL. Nanopure water was used as the blank and the solution was then placed in a cuvette which was then measured inside the Vernier pH spectrophotometer. The absorbance and λmax of this solution was then recorded in third column of Table 3. The cherry juice and nanopure water solution was calculated by using the linear regression equation seen in Figure 1. The cherry juice concentration and nanopure was 2.26 uM. The stock solution was calculated by using m1v1=m2v2. The cherry juice concentra-tion and nanopure water mass, uM, was m1 and the 25 mL of the diluted solution was v1. The v2 was the 0.50 mL of the cherry juice. After calculations, the m2 was calculated. It ended up being 131 µM which was the mass of the stock

(Sinno et al, 2011). It also helps in the transfer of white blood cells to the wound, improves resistance to infection and increases capillary strength. Since vitamin C is water-soluble, it is difficult to store it in the body, so a regular intake is necessary and dietary sources are green vegetables, potatoes, fruits like orange, kiwi and berries. (Timms, 2011).

The purpose of this lab is to determine how the amount of vitamin C (ascorbic

In this experiment I will be finding out which fruit juice contains the most vitamin C. I will be using a method similar to titration but I will be using a syringe instead of a burette.

Vitamin C is an organic compound that is also known as ascorbic acid. The molecular formula for Vitamin C is C6O8H6. This structure contains a 5-membered ring. Vitamin C contains 4 alcohol functional groups, an alkene, and an ester. Within the ring it contains one double bond, the carbon=carbon bond in the ring structure, this is an alkene functional group. The Vitamin C structure also contains an ester which helps form the five-membered ring.

Vitamin C should be taken in through diets, fruits and vegetables so that it can have its best effects and is good for our health. Vitamin C supplements are only used as addition if our bodies do not have enough Vitamin C.

Vitamin C is crucial for survival for several reasons. For a human body to reach the acme of its physical potential, it must have a daily intake of vitamin C. Deficiency can lead to a fatal symptom known as scurvy. Likewise, iron absorption will be more difficult resulting in iron-deficiency anemia (Smith, Primio & Humphrey-Murto, 2011). However, this nutrient is essential for bodily functions as well. Vitamin C is required for hormone production which is seen by the fact that the highest concentration of it in the human body is in the pituitary and adrenal glands (Emsley, 2004). Moreover, this vitamin aids in protection against free radicals and stress. Vitamin C is also imperative because it assists in the growth of various body parts, including teeth, cartilage, and dentine. This acid is integral for bone development and to heal fractured or broken bones. As said before, “Vitamin C is important in the absorption and metabolism of many nutrients that affect production of red blood cells”, including iron absorption (Smith, Primio, & Humphrey-Murto, 2011). DIRECT QUOTE WITHOUT AUTHOR. Similar to its importance to humans, vitamin C is vital for plant life as well. Plants require the alcohol for growth processes.

Vitamin C, or ascorbic acid, is a well-known supplement that is essential to the human body. Vitamin C helps grow and repair body tissue, make collagen, heal wounds, and strengthen bones and teeth. Unfortunately, the body does not produce this vitamin itself, therefore it must be obtained from another source. Vitamin C is present in significant amounts in both fruits and vegetables. These foods are commonly pasteurized – a process that applies heat to destroy pathogens that cause spoilage in food. Pasteurization is great for preserving foods, but its effects on the food’s contents are important to consider. This process could affect the levels of ascorbic acid in the foods being consumed for their vitamin C content. Specifically, orange juice, one of the most popular sources of vitamin C, is going to be used to examine the effects of pasteurization on ascorbic acid levels in this experiment.
