- REFLECT AND APPLY You are in the process of determining the amino acid sequence of a protein and must reconcile contradictory results. In one trial, you determine a sequence with glycine as the N-terminal amino acid and asparagine as the C-terminal amino acid. In another trial, your results indicate phenylalanine as the N-terminal amino acid and alanine as the C-terminal amino acid. How do you reconcile this apparent contradiction?arrow_forwardREFLECT AND APPLY An amylose chain is 5000 glucose units long. At how many places must it be cleaved to reduce the average length to 2500 units? To 1000 units? To 200 units? What percentage of the glycosidic links are hydrolyzed in each case? (Even partial hydrolysis can drastically alter the physical properties of polysaccharides and thus affect their structural role in organisms.)arrow_forwardREFLECT AND APPLY The enzyme D-amino acid oxidase has a very high turnover number because the D-amino acids are potentially toxic. The KM for the enzyme is in the range of 1 to 2 mM for the aromatic amino acids and in the range of 15 to 20 mM for such amino acids as serine, alanine, and the acidic amino acids. Which of these amino acids are the preferred substrates for the enzyme?arrow_forward
- REFLECT AND APPLY Consider the structures of arabinose and ribose. Explain why nucleotide derivatives of arabinose, such as ara-C and ara-A, are effective metabolic poisons.arrow_forwardREFLECT AND APPLY A researcher claims to have discovered a variant form of glycogen. The variation is that it has very few branches (every 50 glucose residues or so) and that the branches are only three residues long. Is it likely that this discovery will be confirmed by later work?arrow_forwardREFLECT AND APPLY Would you expect cross-linking to play a role in the structure of polysaccharides? If so, how would the cross-links be formed?arrow_forward
- REFLECT AND APPLY Pectin, which occurs in plant cell walls, exists in nature as a polymer of D-galacturonic acid methylated at car- bon 6 of the monomer. Draw a Haworth projection for a repeating disaccharide unit of pectin with one methylated and one unmeth- ylated monomer unit in (14) linkage.arrow_forwardREFLECT AND APPLY The process of protein folding is spontaneous in the thermodynamic sense. It gives rise to a highly ordered conformation that has a lower entropy than the unfolded protein. How can this be?arrow_forwardREFLECT AND APPLY Sulfanilamide and related sulfa drugs were widely used to treat diseases of bacterial origin before penicillin and more advanced drugs were readily available. The inhibitory effect of sulfanilamide on bacterial growth can be reversed by p-aminobenzoate. Suggest a mode of action for sulfanilamide.arrow_forward
- REFLECT AND APPLY Starting with a Fischer projection of D-fructose, write equations showing the formation of -D-fructopyranose, -D-fructofuranose, -D-fructopyranose, and -D-fructofuranose.arrow_forwardREFLECT AND APPLY Suggest a reason why the cell membranes of bacteria grown at 20C tend to have a higher proportion of unsaturated fatty acids than the membranes of bacteria of the same species grown at 37C. In other words, the bacteria grown at 37C have a higher proportion of saturated fatty acids in their cell membranes.arrow_forwardREFLECT AND APPLY In lipid bilayers, there is an orderdisorder transition similar to the melting of a crystal. In a lipid bilayer in which most of the fatty acids are unsaturated, would you expect this transition to occur at a higher temperature, a lower temperature, or the same temperature as it would in a lipid bilayer in which most of the fatty acids are saturated? Why?arrow_forward
