Interpretation:
The chemical changes in the conversion of adenosine to xanthine have to be given.
Concept introduction:
Uric acid is the end product of the breakdown of purine nucleosides and urate ion is formed by the loss of its acidic hydrogen. After a number of enzymatic steps, adenosine produces xanthine which is then converted to uric acid.
Gout is the condition by which the uric acid production increases and the treatment of gout relies on allopurinol. Allopurinol is a structural analog of hypoxanthine which is a precursor of xanthine in the formation of urate.

- Which of the following are positive for the production of indole from the amino acid tryptophan?arrow_forwardA decapeptide was isolated from a thermophilic bacteria. Treatment of this peptide with 2- mercaptoethanol gave 2 pentapeptides. Further analysis of this peptide gave the following data: Trypsin: (M,Y), (K,Y,M), (K, 2A, 2C) Chymotrypsin: (2K, 2A, 2C, Y), (M), (Y,M) What is the primary structure of the decapeptide? Thank you.arrow_forwardWhy is trypsin an unusual name for an enzyme? (What is the convention for enzyme names?) .arrow_forward
- What is the end product of catabolism of the pyrimidine base thymine? What circumstances cause excess amounts of this end product, and why doesn’t this molecule (unlike uric acid, the end product of purine catabolism) cause a gout-like illness?arrow_forwardA pentapeptide was found to have the composition Ala Arg Gly Pro Trp. Reaction of the pentapeptide with Sanger’s reagent, followed by hydrolysis, gave the DNP derivative of proline. Treatment of the pentapeptide with carboxypeptidase initially produced alanine. Treatment of the pentapeptide with trypsin gave a tetrapeptide which, when treated with chymotrypsin, produced a tripeptide. What is the sequence of the pentapeptide? (note: trypsin cleaves after basic amino acids) *arrow_forwardThe following figure depicts the breakdown of purine nucleotides, which are the nucleotides with adenine and guanine bases found in DNA and RNA. Note that uric acid is the final product of this pathway in humans. Dr. Miloslavsky and the patient discussed her history of treatment with three different drugs. You will learn more about these specific drugs as we proceed with this case. These drugs all act in some way to affect the breakdown of purines. Which of the following would reasonably be effective therapies for treating gout? (select all that apply) A drug that increases the concentration of purines entering this pathway. A drug that catalyzes the breakdown of uric acid into another compound. A drug that blocks the enzyme that catalyzes the formation of uric acid. A drug that catalyzes the breakdown of guanosine into guanine.arrow_forward
- A 47-year old man with a history of severe allergy to penicillin is hospitalized and undergoes the treatment for bacterial meningitis. After 5 days of treatment he complains of severe headache, visual disturbances and general malaise. His blood test shows a severe anemia. Which one of the following drugs may be responsible for this adverse reaction? Explain. Doxycycline Gentamicin Amoxicillin Azithromycin Chloramphenicol Tetracyclinesarrow_forwardGlucose has been found to react nonenzymatically with hemoglobin, through Schiff base formation between C-1 of glucose and the amino termini of the B chains. How might this finding be applied in monitoring diabetic patients?arrow_forwardThis is remdesivir, one of the drugs being used in the treatment of COVID-19. Label the indicated carbons as R, S, or neither. b); NH2 HO OHarrow_forward
- Gout is characterized by elevated uric acid concentrations in blood and urine due to a variety of metabolic abnormalities that lead to the overproduction of purine nucleotides. Allopurinol is used in the treatment of gout because this drug, and its metabolic product, alloxanthine, act as inhibitors of: а) Xanthine Oxidase PRPP synthetase c) Hypoxhantine guanine phosphoribosyl b) Adenyl succinate synthase d) transferase e) Nucleotidesarrow_forwardWhy are the protein-digesting enzymes trypsin and chymotrypsin secreted as the zymogen chymotrypsinogen?arrow_forwardHomocystinuria is caused by a defect in cystathionine beta-synthase (or 13-synthase), which leads to an accumulation of homocysteine in the blood. This accumulation causes symptoms such as a tall, thin frame, flushed cheeks, and osteoporosis (thinning of the bones). These individuals should limit their intake of proteins that contain methionine, such as egg whites. Using your understanding of biochemistry, explain why people with Homocystinuria should not consume egg whites and other such proteins.arrow_forward
