2. The molecular formula for glycine is C2HsO2N. What would be the molecular formula for a linear oligomer made by linking ten glycine molecules together by condensation synthesis? A C20H5oO20N, B CoH3 OuN C C20H4OOIoN e None of the above 3. The resonance structures that can be drawn for the peptide bond indicate that the peptide bond a still isn 't completely understood by chemists B is stronger than an ordinary single bond c has partial double bond character d actually extends to the a-carbon e The second and third choices are both correct 4. The peptide hormone involved in controlling blood pressure is a testosterone b oxytocin d interferon B E glutathione 5. Aspartame, the synthetic sweetener(a k a NutraSweet ), is A b also secreted by the posterior pituitary gland in response to thirst c a glucose derivative D not digested (i.e. hydrolyzed) by humans is nearly 10,000-fold sweeter than sucrose, by weight ※<4> 1. The peptide, Val-Lys-Glu-Met-Ser-Trp-Arg-Ala, was digested with cyanogen bromide(CnBr) to produce a Val-Lys Glu-Met-Ser Trp-Arg-Ala B Val-Lys-Glu-Met-Ser-Trp Arg-Ala c Val-Lys-Glu-Met D Val-Lys-Glu Met-Ser-Trp-Arg-Ala E Val-Lys-Glu-Met-Ser Trp-Arg-Ala 2.
