Soluble Vitamins SCI/241 According to the textbook “vitamins are organic compounds that are essential in the diet in small amounts to promote and regulate body processes necessary for growth‚ reproduction‚ and the maintenance of health.” (Grosvenor & Smolin‚ Ch. 7 pg. 200) Vitamins are classified into two groups based of their solubility‚ as some are soluble in water and others are soluble in fat‚ with these characterizations we are able to know more about how the different types of vitamins are

person needs a daily intake of Vitamin C to stay healthy; therefore‚ one should be aware of what fruits he/she should ingest daily or more days to obtain stronger stamina and the abundance of antioxidants in the body to reverse oxidation. Vitamin C or L-ascorbic acid is essential for normal growth of humans and it helps in the repair and reconstruction of body tissues lost over time. It is an antioxidant that blocks the damage caused by free radicals. People who take Vitamin C daily tend to build up a

tamin C‚ ascorbic acid‚ is one of the most important vitamins found in citrus juices‚ including orange juice. Often projects find that orange juices made from frozen concentrated orange juice (FCOJ) have the highest vitamin C levels as compared to freshly squeezed or not-from-concentrate (NFC) juices. This is probably due to the fact that vitamin C degrades over time in fresh and NFC‚ but doesn’t degrade as much in FCOJ due to it being frozen until reconstitution. If one is comparing a NFC product

OBJECTIVE To investigate the vitamin C content of different fruit juices. To identify which fruit juices has higher vitamin C content and the lowest vitamin C content. To determine the standard curve of vitamin C based on percentage of vitamin C. To differentiate between fresh juices and carton juices. To consider the reliability and validity of the results. PROBLEM STATEMENT Which type of fruit juices has the most vitamin C content? HYPOTHESIS The smaller the amount of the fruit juices

E20-1 Experiment 20 Consumer Chemistry: Vitamin C in Fruit Juices The Task The goal of this experiment is to determine the concentration of vitamin C in a range of different fruit juices (fresh and preserved) using titration and to rank these sources of vitamin C. Skills At the end of the laboratory session you should be able to: * use a pipette correctly‚ * use a pipette filler safely‚ * manipulate a burette and carry out a quantitative titration properly‚ * weigh a sample

Calculations should be in your notebook before arriving to lab. 2. Provide the structure of vitamin C in its reduced form (ascorbic acid)‚ its ionized form (ascorbate ion- this is at equilibrium with reduced form when dissolved)‚ and its oxidized form (dehydroascorbate). 3. Why do you

Investigating Vitamin C Background Vitamin C is found in green vegetables‚ fruits‚ and potatoes. It is essential for a healthy diet. The chemical name for vitamin C is ascorbic acid. Ascorbic acid is a good reducing agent and therefore it is easily oxidised. Methods for the detection of vitamin C involve titrating it against a solution of an oxidising agent. Where to start There are several oxidising agents that can be used and a commonly used one is 2‚6-dichlorophenol-indophenol or DCPIP

1. Vitamins are good for everyone’s health. Discuss A vitamin is an organic compound required by an organism as a vital nutrient in limited amounts. An organic chemical compound is called a vitamin when it cannot be produced in sufficient quantities by an organism‚ and must be obtained from the diet.
