Concept explainers
(a)
Interpretation: The products formed by the treatment of angiotensin I with trypsin are to be predicted.
Concept introduction: The name of amino acids is represented by the one-letter and three-letter abbreviations. There are some enzymes used to hydrolyzed the specific sites of peptides. The carboxypeptidase enzymes are used to identify the C-terminal amino acid.
(b)
Interpretation: The products formed by the treatment of angiotensin I with chymotrypsin are to be predicted.
Concept introduction: The name of amino acids is represented by the one-letter and three-letter abbreviations. There are some enzymes are used to hydrolyzed the specific sites of peptides. The carboxypeptidase enzymes are used to identify the C-terminal amino acid.
(c)
Interpretation: The sequence of the amino acid in angiotensin
Concept introduction: The name of amino acids is represented by the one-letter and three-letter abbreviations. There are some enzymes are used to hydrolyzed the specific sites of peptides. The carboxypeptidase enzymes are used to identify the C-terminal amino acid.

- 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_forwardSome penicillins cannot be administered orally because their β-lactam is rapidly hydrolyzed by the acidic environment of the stomach.

- Which will have higher melting point between tripalmitin and tripalmitolein?arrow_forwardN-Methylpyrrolidine has a boiling point of 81 °C, and piperidine has a boiling point of 106 °C. Tetrahydropyran has a boiling point of 88 °C, and cyclopentanone has a boiling point of 141 °C. These two isomershave a boiling point difference of 53 °C. Explain why the two oxygen-containing isomers have a much larger boilingpoint difference than the two amine isomersarrow_forwardFurosemide is a diuretic medication used to treat patients with congestive heart failure (CHF).
