were liquid‚ oily‚ and it had a banana smell. Introduction Artificial flavoring is commonly used in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester

Dean Assenza Pygmalion Synthesis Essay Outline Introduction: One’s culture is a key part of their identity. Culture can reside in a nation‚ family‚ ethnicity‚ a religion‚ etc. Mahatma Gandhi once said‚ “A Nation’s culture resides in the hearts and in the soul of its people”. One’s culture is usually seen through the religion and traditions of their nation; therefore this influences their everyday lives and their behavior.. Culture influences one’s appearance or the way they talk‚ but also

Abstract This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low

2013) Protease inhibitors can be used in medicine to treat different diseases and viruses which depend on protease for its mechanism of action. Protease inhibitors are most commonly used in the treatment of HIV/AIDS. Protease is responsible for the synthesis of new viral cells which would cause HIV to spread to uninfected cells. When the protease is introduced however‚ non-infectious vial particles are produced. The protease involved in HIV is called the HIV protease which is an aspartic protease (San

DNA synthesis inhibitors Nucleic acid inhibitors are chemicals which inhibit the production of nucleic acids including both DNA and RNA. DNA and RNA inhibitors inhibit enzyme action in DNA replication in the same way as the topoisomerase inhibitors we discussed earlier. Topoisomerase inhibitors (1) (10) are chemicals which interfere with the enzymes that allow DNA strands to separate and to re-join‚ a process that is required for the division of bacteria and without which DNA cannot effectively

SYNTHESIS OF THE PHARMACEUTICAL ASPIRIN (ACETYLSALICYLIC ACID) AIM: The aim for this experiment was to synthesise a small amount of aspirin with salicylic acid as the starting product and sulphuric acid as the catalyst. The product obtained from this reaction will be impure and will need to be purified. This will be done by recrystallization. We will then record the products’ melting point and calculate the yield in order to determine the degree of purity of the aspirin sample. Diagrammatic scheme
