Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Glucose is a source of energy that is metabolized into glycolysis to pyruvate yielding ATP. To become more efficient,…

Part I: Separate a mixture of known cations: Pb2+, Fe3+, Al3+, Cu2+, and Ca2+ into individual ions. Perform a series of tests to become familiar with reactions characteristic of each cation. Part II: Separate and identify individual cations in an unknown solution containing a mixture of up to five cations. Use information gathered in part…

Introduction A.Background of the Study The group will conduct the study because the group noticed that teabag extract is dark in colour and it can be use to make ink, and also the group noticed that teabags are made from natural resources. Some kinds of teas are made out of a plant known as Camellis…

VI. RESULTS AND DISCUSSION Aspirin is prepared by the esterification of salicylic acid with acetic anhydride under acidic conditions. The phenol group in salicylic acid is replaced by a carboxyl group through electrophilic substitution. The mechanism for the reaction can be summarized as follows: Figure 11.4. Mechanism for the reaction of salicylic acid and acetic…

For my final project the first compound I synthesized was Dulcin. Dulcin is an artificial sweetening agent that is 200 times as sweet as sucrose. It is also, the second synthetic sweeter that was discovered. The first synthetic sweetener, saccharin, was discovered five years prior to Dulcin. The discovery of Dulcin occurred in 1883. Approximately…

The body uses cholesterol to make vitamin D and various hormones, such as estrogen, testosterone, and cortical. The body can produce all the cholesterol that it is needs, but it also obtains cholesterol from food. Lieberman-Bernhard test: The Lieberman-Bernhard or acetic anhydride test is used for the determination of cholesterol. The formation of a green…

Abstraction This experiment was conducted to synthesise methyl benzoate signifier benzoic acid and methyl alcohol by utilizing the Fischer esterification method. The Fischer exterification technique is utilized in the academic and industrial scenes due to the simplified synthesis and safety parametric quantities of the overall reaction. Both benzoic acid and methyl alcohol are comparatively inexpensive…

The objective of the experiment was to produce two azo dyes: p-nitrobenzene azoresorcinol and methyl orange. The initial step involved mixing p-nitroaniline and resorcinol to create p-nitrobenzene azoresorcinol. In order to form the diazonium salt, we combined a solution containing p-nitroaniline dissolved in hydrochloric acid and water with a sodium nitrite solution. Subsequently, the resulting…

Pre-Lab Analgesic drugs are known for reducing pain, while antiseptic drugs reduce symptoms such as fevers and swelling. However, some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs, the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as;…
