Concept explainers
(a)
Interpretation:
The structural formula for the product formed by the treatment of N-terminal amino group with Sanger’s reagent has to be written and the mechanism of the product formation has to be explained.
(b)
Interpretation:
When bovine insulin is treated with Sanger’s reagent followed by hydrolysis of all peptide bonds, two labelled amino acids Glycine and Phenylalanine are detected. From this information, the conclusion drawn from the primary structure of bovine insulin has to be given.
Concept Introduction:
Sanger’s reagent reacts with the N-terminal amino group of polypeptides and forms the
(c)
Interpretation:
The structural information obtained by Sanger’s reagent and by Edman degradation has to be compared and contrasted.

- A chemically modified guanidino group is present in cimetidine (Tagamet), a widely prescribed drug for the control of gastric acidity and peptic ulcers. Cimetidine reduces gastric acid secretion by inhibiting the interaction of histamine with gastric H2 receptors. In the development of this drug, a cyano group was added to the substituted guanidino group to alter its basicity. Do you expect this modified guanidino group to be more basic or less basic than the guanidino group of arginine?

- Calculate the theoretical yield of 2mL of vegetable oil saponification reaction with 2mL of 6M NaOH and 40mL of saturated salt solution(NaCl). GIVENS: density of the oil = 0.9 g/mL each fatty acid side chain of the oil has 18 C atoms (C_18: the carbonyl carbon, plus a C_17 carbon chain). Assume an average of one unsaturation per side chain.arrow_forwardEncircle the functional groups found in Betacarotene and explain each of their purposes in the compound thoroughlyarrow_forwarda.
