- When oxaloacetic acid and acetyl-coenzyme A (acetyl-CoA) labeled with radioactive carbon-14 in position 2 are incubated with citrate synthase, an enzyme of the tricarboxylic acid cycle, only the following enantiomer of [2-l4C]citric acid is formed stereoselectively. Note that citric acid containing only 12C is achiral. Assign an R or S configuration to this enantiomer of [2-14C]citric acid. (Note: Carbon-14 has a higher priority than carbon-12.)arrow_forwardFollowing is a retrosynthesis for the coronary vasodilator ganglefene. (a) Propose a synthesis for ganglefene from 4-hydroxybenzoic acid and 3-methyl-3-buten-2-one. (b) Is ganglefene chiral? If so, which of the possible stereoisomers are formed in this synthesis?arrow_forwardChoose the product that is expected when the β-pyranose form of compound A is treated with excess ethyl iodide in the presence of silver oxide. The following information can be used to determine the identity of compound A: 1. The molecular formula of compound A is C6H12O6.2. Compound A is a reducing sugar.3. When compound A is subjected to a Wohl degradation two times sequentially, D-erythrose is obtained.4. Compound A is epimeric with D-glucose at C3.5. The configuration at C2 is R.arrow_forward
- Hyaluronic acid, a component of connective tissue, is the fluid that lubricates joints. It is a polymer of alternating N-acetyl-d-glucosamine and d-glucuronic acid subunits joined by β-1,3'-glycosidic linkages. Draw a short segment of hyaluronic acid.arrow_forwardEmil Fischer synthesized l-gulose, an unusual aldohexose that reduces to give d-glucitol.Suggest a structure for this l sugar, and show how l-gulose gives the same alditol asd-glucose. (Hint: d-Glucitol has ¬CH2OH groups at both ends. Either of these primaryalcohol groups might have come from reduction of an aldehyde.)arrow_forwardMannose is an aldohexose with relative stereochemistry AABB. i) Draw the Fischer projection of 2-amino-2-deoxy-D-mannose. ii) Construct the Haworth projection of 2-amino-2-deoxy-D-mannose. iii) Assign the absolute configuration for C-3 in 2-amino-2-deoxy-D-mannose.arrow_forward

When the aldopentose (A) was subjected to a Ruff degradation, D-aldotetrose (C) was generated. The aldotetrose (C) gave an optically active aldaric acid (D) upon oxidation with HNO3. D-aldopentose (A) can be prepared from D-threose by a Killani Fischer synthesis. Propose structure of A through D.arrow_forward

On oxidation with HNO3, X gives an optically inactive aldaric acid. WhenX is degraded to an aldopentose, oxidation of the aldopentose gives an optically active aldaric acid. Determine thestructure of X.(d) Even though sugar X gives an optically inactive aldaric acid, the pentose formed by degradation gives an opticallyactive aldaric acid.
