  • Cognitive Function And Vitamin B1

    synthesis and cell replication. The individual roles of vitamin B12 also essential for human beings. Vitamin B12 can maintain myelin sheath, promote normal growth of nerve cells, and be involved in bone cell metabolism/activity. Vitamin B12 and folic acid reduce homocysteine to methionine, which is then converted into S-adenosylmethionine (SAM), a crucial co-factor for 150+ methyltransferases including glycine n-methyltransferase (GNMT) in the one carbon pathway.(Mitchell, Conus, and Kaput,…

  • Pollution Is Contaminating The World

    The effects are acid rain, global warming, effects on wildlife, heart problems, eutrophication, and depletion of the ozone layer. When fossil fuels are burned, harmful oxides are released in the air. When it rains, the water combines with the oxides and it becomes acid rain. Acid rain has the potential to cause great danger to plants, animals, and humans. Global Warming has been an issue for a while…

  • Pros And Cons Of Genetic Modification Of Crop Species

    The benefits and risks of the scientific method of genetically modifying crop species Since the emergence of agriculture over 10,000 years ago, humans have been altering the genomes of the crops they produce in order to increase the crop quality in many ways, with fruit size and palatability being two obvious examples. Whether this occurred incidentally through the techniques used to cultivate the plants or intentionally through artificial selection, humans have created strains of domesticated…

  • Diels Alder Reaction Lab Report

    Diels-Alder Reaction Objective: The objective of this lab was to do a diels-alder reaction using anthracene, maleic anhydride, and xylene to create 9,10-dihydroanthracene, 10-, -succinic acid anhydride. Experimental: Anthracene (1.00g, 5.61x 10-3 mol), maleic anhydride (0.75g, 7.61x 10-3 mol), xylene (5mL, 4.71x 10-2 mol), and a stir rod were added into a round-bottomed flask. The round-bottom flask was then moved to the hood where the it was attached to a distillation column, placed on…

  • The Importance Of Omega-3 Fatty Acids

    Omega-3 Fatty Acids Omega-3 fatty acids play a big role in a number of bodily functions. They are a group of polyunsaturated fatty acids and are usually found in fatty fish such as salmon, tuna and trout in the form of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (NIH, 2017). Another type of omega-3, called alpha-linolenic acid, is found mainly in plants. Omega-3 fatty acids play a role in muscle activity, blood clotting, digestion, fertility, cell division and growth, brain…

  • Oxysterol Essay

    The role of oxysterols in human body and disease 1. Introduction Oxysterols are 27-carbon derivatives of cholesterol created by spontaneous or enzymatic oxidation (Figure 1, (Brown and Jessup, 2009)). The oxidation of cholesterol occurs either on the side chain or on the sterol core. Side chain oxidation generates, e.g., 24-hydroxycholesterol (24-HC), 25-hydroxycholesterol (25-HC) or 27-hydroxycholesterol (27-HC) while the core oxidation gives rise to ring oxysterols, mostly ring-B oxysterols,…

  • 2-Aminobenzophenone Lab Report

    of solvent-free and green synthetic procedures, we decided to explore the use of tartaric acid catalyst for synthesis of polysubstituted quinolines via Friedlander condensation in high to excellent yields at 70 °C under solvent-free conditions. Initially the reaction between 2-aminobenzophenone (1.0 mmol) and dimedone (1.0 mmol), as the model reaction was examined in the presence varying amount of tartaric acid as catalyst and the results are presented in Table 1. The best result was achieved by…

  • CO2 Concentration Essay

    One of the most widely studied mitigation options for reducing concentration of CO2 in atmosphere involves injecting it into the ocean at great depths, where the gaseous CO2 reacts to form carbonic acid (H2CO3) as shown in equation (2.1). This equation shows various forms of CO2 as it is dissolved in the water (brine). Depending on the pH of the solution, either forms of CO2 may be observed (CO2 (aq), 〖"HCO" 〗_"3" ^"-" , 〖"CO" 〗_"3" ^"2-" ). There are two ways for storing CO2 in ocean, either…
