Organic Chemistry of Metabolic Pathways
Metabolic pathways allude to the arrangement of chemical catalyzed reactions that lead to the transformation of a substance into the final product. Metabolic pathways incorporate a progression of reaction where the substrate is changed continuously and the transitional metabolites are persistently recovered.
Glucogenesis
Glucogenesis is a metabolic pathway in which glucose is produced from carbon substrates that are not carbohydrates. This process is observed in plants, animals, fungi, bacteria and other micro organisms. The general definition for glucogenesis or gluconeogenesis is as follows,

- Draw the product that valine forms when it reacts with CH3COCl, pyridine; then H2O. You do not have to consider stereochemistry. Do not draw organic or inorganic by-products. Draw the product in neutral form unless conditions are clearly designed to give an ionic product. Include cationic counter-ions, e.g., Na+ in your answer, but draw them in their own sketcher. Do not include anionic counter-ions, e.g., I-, in your answer.A 0.8065-g sample containing dimethylphthalate (DMP), C6H4(COOCH3)2 (194.19 g/mol), and unreactive species was refluxed with 50.00 mL of 0.1215 M NaOH to hydrolyze the ester groups (this process is called saponification). C6H4(COOCH3)2 + 2OH- ------> C6H4(COO)22- + 2 CH3OH After the reaction was complete, the excess NaOH was back titrated with 24.27 mL of 0.1644 M HCl. Calculate the percentage of dimethylphthalate (DMP) in the sample. Express your answers with 3 decimal placesThanks for the answer - so then is there only one product? I was assuming theere would be 2 separate compounds as the products.
- Determine the branch points and reducing ends of amylopectin. A 0.5g sample of amylopectin was analyzed to determine the fraction of the total glucose residues that are branch points in the structure. The sample was methylated and then digested, yielding 50 μmol of 2,3-methylglucose and 0.4 μmol of 1,2,3,6-tetramethyl glucose. (MWglucose = 162 g/mol, minus H2O) What fraction of the total residues are branch points? How many reducing ends does the amylopectin have?After graduating from your PhD, you are now working as a post-doctoral researcher in BASF , the world’s largest multinational chemical company. The management of your R&D department decided to look at the potentiality of chloroform-methanol mixture in removing the lipids of various biological systems. Your boss, a senior scientist at your department, thinking about the hydroxyl group on the alcohol and thet hree chlorines on the CHCl3 , suggested that the mixture is probably non-ideal. Being one of her brightest colleagues, she then tasked you to graph the partial molar enthalpies of the chloroform methanol mixture as a function of mole fraction. Ardently, you accepted the challenge and went back to your office. After several hours of searching, you finally come up with enthalpy of mixing data at 50oC fort his mixture (See the picture). Please provide the graphs that the boss has asked you for. Put both curves on the same graph. Note: provide your excel file for thisWhen some sugars dissolve in water they spontaneously undergo changes in optical rotation called mutarrotation. The Mutarrotation of D-glucopyranose is catalyzed by acid and bases. 2-Hydroxypyridine is a more effective catalyst than phenol and pyridine for this reaction because: a.Both oxygen and N in 2-hydroxypyridine act as bases increasing the rapid interconversion of sugar b. The OH of 2-hydroxypyridine serves as the base while the current N as the acid. c. 2-hydroxypyridine acts both as a base to remove the proton from the hydroxyl group in the hemiacetal and as an acid to provide a proton to the oxygen in the hemiacetal. d.Phenol and pyridine are very expensive.

You went to chemical storage room to take some D-lyxose to use as the starting material. But there you found that labels had fallen off from the bottles containing D-lyxose and D-xylose. How could you determine which bottle contains D- lyxose?What the "fractional saturation, YO2"? Please use more than 100 words.
