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

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

resolution and detection limits, so that the to walk two dimensions. To phospholipids visible on the TLC plates are used detection reagents. spots corresponding phospholipids may be carbonized by the addition of phosphomolybdic acid, sulfuric acid or copper sulfate in phosphoric acid, and then heating of the sample. The result charred spots can be scraped off the plate and measured by densitometry. In order to visualize the spots without charring, solutions such as rhodamine 6G or berberine can be used

Oral hygiene, concerned from ancient times, various civilizations, with the first form of toothpaste making its appearance in Egypt, in 2000 BC. Consisting of pumice powder and vinegar, this formula although whitened the teeth, caused damage to the enamel. Other variants of toothpaste, created by Greeks and Romans, who observed that the urine, which contain ammonia, component which also exists in modern toothpaste, combined with abrasives, such as crushed bones, shells, charcoal and bark, could freshen

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

A. Rationale Astaxanthin, similar to a variety of carotenoids, is a colorful antioxidant and a fat-soluble pigment. The presence of the extended polyene system located at the center of the substance causes it to not only give color but also responsible for the antioxidant properties of carotenoids such as astaxanthin that can perform a free radical scavenging and quenching ability (Dalei and Sahoo, 2015). Also, astaxanthin is a very unique carotenoid which cannot be converted into retinol in the

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)

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

I. INTRODUCTION This report discusses an experiment, the objective of which was to determine the classification of six known chemicals: sodium nitrate, barium chloride, silicon carbide, naphthalene, urea, and antimony and two unknown chemicals XIa and XIb. Since each type of chemical (ionic, molecular, macromolecular and metallic) has its own set of properties, by testing these properties and finding them out for each chemical, it was possible to classify them. The properties tested during this

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.

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

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

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

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

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
