(a)
To determine: The structure for glutathione that is consistent with the given information and the reason corresponding to the fact that glutathione fails to give a normal product from Edmann degradation, even though it gives a normal product from the Sanger reagent followed by hydrolysis.
Interpretation: The structure for glutathione that is consistent with the given information is to be shown and the reason corresponding to the fact that glutathione fails to give a normal product from Edmann degradation, even though it gives a normal product from the Sanger reagent followed by hydrolysis is to be stated.
Concept introduction: The process in which a proper series of amino acids is maintained peptide chain is known as Edmann degradation. This process includes the labelling of terminal amino residue followed by the cleavage of this terminal amino residue from the peptide chain. The peptide bonds between other amino acids do not get disturb during this process.
(b)
To determine: The structure for glutathione disulphide that is formed by oxidation of glutathione and the balanced r-equation for the reaction of glutathione with hydrogen peroxide.
Interpretation: The structure for glutathione disulphide that is formed by oxidation of glutathione and the balanced equation for the reaction of glutathione with hydrogen peroxide are to be predicted.

- Several compounds have been found to inhibit -lactamase, and drugs based on these compounds can be taken in combination with penicillins and cephalosporins to restore their effectiveness when resistance is known to be a problem. The commonly prescribed formulation called Augmentin is a combination of the -lactamase inhibitor shown below with amoxicillin (shown above). It is used to treat childhood ear infections when resistance is suspected, and many kids know it as the white liquid that tastes like bananas. Which of the statements below are true statements? 1. The stereochemistry of the fusion between the four-and five-membered rings in the inhibitor and amoxicillin are different. 2. The inhibitor possesses enol ether and allylic alcohol functional groups while the antibiotic possesses a phenol and a secondary amide functional group. 3. Neither the inhibitor nor the antibiotic contains strained rings. 4. Both 1 and 2 are true.arrow_forwardThe first step in the catabolism of most amino acids is the removal of the nitrogen atom by transfer to an a-keto acid, a reaction catalyzed by an enzyme called a transaminase. The a-keto acid acceptor is often a-ketoglutarate. Modify the structures in the product to show the products of the transamination of cysteine. Be sure to show functional groups with the charge and number of attached hydrogen atoms appropriate for pH 7.4. transaminase + O=C H₂N-CH + CH₂ CH₂ CH₂ SH Incorrect H₂N || CH | CH₂ | CH₂ I || O || n | CH₂ T SHarrow_forwardAn octapeptide contains the following amino acids: Arg, Glu, His, Ile, Leu, Phe, Tyr, and Val. Carboxypeptidase treatment of the octapeptide forms Phe and a heptapeptide. Treatment of the octapeptide with chymotrypsin forms two tetrapeptides, A and B. Treatment of A with trypsin yields two dipeptides, C and D. Edman degradation cleaves the following amino acids from each peptide: Glu (octapeptide), Glu (A), Ile (B), Glu (C), and Val (D). Partial hydrolysis of tetrapeptide B forms Ile–Leu in addition to other products. Deduce the structure of the octapeptide and fragments A–D.arrow_forward
- Aspartame (Nutrasweet®) is a remarkably sweet-tasting dipeptide ester. Complete hydrolysis of aspartame gives phenylalanine, aspartic acid, and methanol. Mild incubation with carboxypeptidase has no effect on aspartame. Treatment ofaspartame with phenyl isothiocyanate, followed by mild hydrolysis, gives the phenylthiohydantoin of aspartic acid.Propose a structure for aspartame.arrow_forwardGive the polarity, melting point, boiling point, solubility, and state at room temperature of the following: Linoleic acid Tripalmitin Triolein Phosphatidylcholine(28:0) Phosphatidylinositol(34:1) Phosphatidylserine(36:2) Phosphatidylethanolamine(38:6) Cholesterolarrow_forwardBicarbonate (shown below) functions as a conjugate base within the plasma's bicarbonate buffer system.
