Hepatitis C Virus Hepatitis is an inflammation of the liver‚ which can be caused by several different viruses. It can also be acute or chronic‚ depending on the particular virus and stage of the disease. The different types of hepatitis are hepatitis A (HAV)‚ hepatitis B (HBV)‚ hepatitis B- associated delta (HDV)‚ hepatitis C (HCV) (Porth 2005). These viruses are capable of being transmitted in many different ways but each one will instigate a viral response and inflammation within the liver

antioxidants such as vitamin C and polyphonols are released from tea leaves during brewing. Hence people claim that drinking tea could prevent diseases like cancers. In this experiment‚ DCPIP solution is used to test the amount of vitamin C in the tea sample. DCPIP solution is a blue substance that would turn from blue color to pink with acids while turn from blue color to colorless with ascorbic acid (vitamin C). Therefore the DCPIP solution is used to test the concentration of vitamin C in a certain

We suspect that this method being repeated would result in ongoing different outcomes Double blind refers to (generally) human trials where neither the scientists nor the participants know who belongs to which group until the end i.e. in this instance‚ participants would not know if they were taking a placebo or an actual Vitamin C pill and scientists

Apples have a good claim to promote health. They contain Vitamin C‚ which aids the immune system‚ and phenols‚ which reduce cholesterol. They also reduce tooth decay by cleaning one’s teeth and killing off bacteria. It has also been suggested by Cornell University researchers that the quercetin found in apples protects brain cells against neuron-degenerative disorders like Alzheimer’s disease. An apple a day may not keep any physicians at bay‚ but apples are very nutritious. They are high in fiber

Determination of Vitamin C Concentration by Titration (Redox Titration Using Iodate Solution) Introduction This method determines the vitamin C concentration in a solution by a redox titration with potassium iodate in the presence of potassium iodide. Vitamin C‚ more properly called ascorbic acid‚ is an essential antioxidant needed by the human body (see additional notes). When iodate ions (IO3−) are added to an acidic solution containing iodide ions (I−)‚ an oxidation-reduction reaction occurs;

Vitamins are micronutrients they are either water soluble or fat soluble. They are organic compounds that are needed in small quantities to sustain life and maintain proper bodily functions. There are several types of vitamins but I have found Vitamin C to be one of the most important vitamins that the body require

ascorbic acid content in mg per mL of canned orange juice. Introduction: Vitamin C is highly water-soluble and has both acidic and strong reducing properties. It occurs naturally in many animals and plants such as the plants of the fruits used in this lab. Vitamin C exist naturally in the L-ascorbic acid form. It is a strong reducing agent and when oxidative stress is present‚ it easily converts to the oxidized form which is. Vitamin C is an essential nutrient in humans because it functions as a cofactor
