Glutamic acid Essays

Assignment 3: Synthesis and Characterisation of L-glutamic acid: Procedure: 1) Approximately 4.40g of L-glutamic acid was added to 0.1L of water. The solute was dissolved completely using a sonic bath. The solution was placed in a thermostatic bath at 80°C and left for 30minutes. 2) After this period of time, the solution was removed and equally distributed into three boiling tubes labelled A,B&C. 3) Then, the boiling tubes were left in a water bath at 45°C. After 5minutes, the boiling tub, labelled

When you eat at a restaurant, do you usually think about where your food come from and how it was managed before being served at your table? This is a question that not many of us ask ourselves but takes a big role in our lives; just as they say, you are what you eat. In most of the cases the food that you are eating was put under a lot of stress and was treated in an inhumanly manner when it was still alive. probably this is not the first time that we have heard this; provably you have read an article

Discovered by a Japanese chemist professor named Kikunae Ikeda in 1908, MSG is short for monosodium glutamate, which is a white, odourless free flowing crystal and is the sodium salt of glutamic acid. Its chemical properties are that it is soluble in water, doesn’t decompose and its functional groups are amines, ketones and aldehydes. Ikeda, a professor at the Imperial University of Tokyo discovered that humans can come across a fifth taste which is called umami, derived from the word umai, meaning

corresponds with the amino acid arginine. This was repeated for each trial of each leaf and the amino acids were identified. Retention factors and closest corresponding amino acids Rf (A) Nandina domestica Amino acid Buxus sempervirens Amino acid Stachys byzantina Amino acid Trial 1 0.200 arginine 0 none 0 none Trial 2 0.345 threonine 0.257 glycine 0 none Trial 3 0.186 arginine

Amino acids are the building blocks of life. They are tiny molecules that contain nitrogen. There are twenty-two naturally occurring amino acids, twenty of these are found in human cells. These twenty are the building blocks of the human body. They hook together to form enzymes, hormones, immune molecules and neurotransmitters. The human body has the ability to make some of these, but others must come from food. Non-Essential From the time humans are infants, their bodies produce non-essentials

Glutathione is a combination of three amino acids or simple building blocks of protein - glycine, glutamic acid, and cysteine. It is naturally produced by the body, similar to alpha lipoic acid and coenzyme Q10, and can be found in every cell. Glutathione functions as a vital antioxidant in the body. One of the most well-known glutathione benefits is that it is very useful in fighting free radicals – molecules that could harm the cells in the body. Glutathione is important in a lot of chemical reactions

titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due

waters (Environment Canada 2012). Through a dual oxidation process, Nitrate is formed in a reaction of Nitrogen with Ammonium ion producing fertilizer and manure. The oxidation state of a nitrate compound is 1- . Nitrate is the conjugate base of nitric acid (HNO3), a strong

role of stomach acid Chapter 14 section 1 Noopur Rajendra Grade – 11AA 25/04/2016 Ms. Sara Kassem Sharjah American International School Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produces. Abstract Hydrochloric acid, which is also called HCl, is a highly corrosive acid. It is a strong

oxygen in extreme cases it could cause death. It could react with other chemicals causing more sickness. If you consume nitrate then you could just get small stomach flu, but when pregnant, or a baby it could cause much worse because your stomach acids are different.

The aim of the investigation was to determine the effect of pH on the rate at which catalase decomposes hydrogen peroxide and consequently answer the researchable question “How does pH influence cells and consequently an organism”. The hypothesis, “As the pH deviates from 7 the initial rate of oxygen production will decrease” is supported by the results. The trend displayed in Figure 3 is, as the pH deviates from 7 the initial rate of reaction decreases. Figure 3 shows that the rate of reaction (%O2/s)

The temperature of the water was then recorded to the nearest 0.1⁰C. Then the melting points of phenylacetic acid, o-anisic acid, and benzilic acid were determined by the use of a Mel-Temp. The unknown sample was obtained from the chemical stockroom. A small scale of crystals from unknown was placed in a test tube with the following solvents: cyclohexane, hexane, toluene, diethyl

The objective of the Bromocresol Green Equilibrium System Lab was to determine if the equilibrium constant, K, was a true constant at constant temperature. To determine this, the value of the constant was found at different concentrations of HIn, HIn-, and at varying pH, which was used to determine the concentration of H+. K was found using the equation K= [HIn]/([In-][H+]). In order to be a true constant, none of the values of K found should differ from the average by more than two standard deviations

hydoxyproline, Serum ascorbic acid, Serum calcium, Urinary calcium, Serum sialic acid, Serum hexosamine, Serum inorganic phosphate were estimated by spectrophotometic method. Result: The study

This 1938 Palmolive soap bar advertisement utilizes its art style along with rhetorical devices such as logos, pathos and ethos. Logos is being utilized through the doctor 's recommendation as well as mentioning on how it helps reduce dry skin. The advertisement also cites the rhetoric device of pathos by using scare tactics to convince its readers to use Palmolive soap. Ethos is presented to encourage the use of Palmolive soap through the notion that women are wanting to look beautiful for their

The Gatorade ad is effective because it appeals to sports fans and athletes and self-actualization needs.It features a basketball player, Dwyane Wade, drinking a bottle of Gatorade.He takes up the entire page and has his back to the camera. Wade is looking up towards something in the distance. The orange color of the Gatorade bottle stands out against the background, which is faded. There is a gym in the background with a window at the top left of the page , with a faded Miami Heat logo near the

Discussion: In this experiment, freezing point depression was used to determine the molar mass of three unknown solids. First, the freezing point of the mixture of ice and water was determined, as freezing occurs when both the solid and liquid phases pre-present together. The temperature when the ice and water mixture reached equilibrium was recorded. Then, the solution of the unknown solids was prepared and its freezing point was determined. Then the equation of molarity allowed the experimenters

The topic that the scientist has researched is the reaction rate of different particle sizes. In the experiment, the scientist will discover how the particle size of Alka Seltzer affects the rate of chemical reaction with water. The independent variable in the experiment is the particle size of the Alka Seltzer, while the dependent variable is the rate of reaction, or the volume of Carbon dioxide. The volume of carbon dioxide will be measured in ml. Also, a few of the constants in the experiment

compounds, the ketone obtained at the end of the experiment could only be one of four products, cyclopentanone, cyclohexanone, 3-heptanone, or 2-heptanone. In order to retrieve one of these ketones, first 1.75g of unknown D was obtained. 1mL of Acetic acid was then added to Unknown D and the solution was stirred. Next, 15mL of sodium
