Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. What causes protein synthesis to occur? Instead recognition and binding to the ribosome rely on a component thatRead More →
Purine biosynthesis occurs in the cytosol of all cells. The purine ring is built up in a series of 11 enzyme catalysed steps. Each enzyme is oligomeric, which means it contains several monomers. Intermediate products that are produced during the reaction are not released. What is de novo purine synthesis?Read More →
Chromopeptide A, a highly cytotoxic depsipeptide from the marine sediment-derived bacterium Chromobacterium sp. HS-13-94. Which drug contains phenothiazine heterocyclic nucleus? Among the most widely used phenothiazines are chlorpromazine (marketed under Thorazine and other trade names), thioridazine (Mellaril), and trifluoperazine (Stelazine). Which of the following compound is starting material for synthesisRead More →
Answer: Ribosomes They are found both free and attached to the surface of the rough endoplasmic reticulum and mitochondria. Ribosomes are known as the protein factory of the cell. Which organelle is known as protein factory and why? > Ribosomes are also called ribonucleoprotein and it has important roles inRead More →
You can also use the Williamson synthesis to produce cyclic ethers. You need a molecule that has a hydroxyl group on one carbon and a halogen atom attached to another carbon. This molecule will then undergo an SN2 reaction with itself, creating a cyclic ether and a halogen anion. HowRead More →
Glucose inclusion in the nucleotide sugar (UDPG) gives it the necessary reactivity to participate in the synthesis of glycogen. Glucose is activated by binding to UDP. Is UTP used in glycogen synthesis? UDP-glucose enters the synthesis of glycogen. UTP is used in the metabolism of galactose, where the activated formRead More →
Organometallic Compounds are used both as a catalyst and reagent in the synthesis of organic compounds such as pharmaceutical products. One of the major advantage of Organometallic Compounds is their high reactivity. With the help of organometallics, reactions can easily be carried out. What are the properties of organometallic compounds?Read More →
Avoid straddling the fence As with an argumentative essay, when writing a synthesis essay, you need to choose the side you’re on in the argument and show evidence from your sources that will substantiate your claim. Finding common threads across various sources requires higher-order level thinking skills. What should beRead More →
Isocyanates are produced from amines by phosgenation, i.e. treating with phosgene: RNH2 + COCl2 → RNCO + 2 HCl. These reactions proceed via the intermediacy of a carbamoyl chloride (RNHC(O)Cl). Owing to the hazardous nature of phosgene, the production of isocyanates requires special precautions. Which classification of pesticides includes carbamates?Read More →
Answer: Ethers generally undergo chemical reactions in two ways: Cleavage of C-O bond: Ethers are generally very unreactive in nature. When an excess of hydrogen halide is added to an ether, cleavage of C-O bond takes place leading to the formation of alkyl halides. The order of reactivity is givenRead More →
