Chapter 29.4, Problem 5P

Evidence for the role of acetate in fatty-acid biosynthesis comes from isotopelabeling experiments. If acetate labeled with 13C in the methyl group (13CH3CO2H) were incorporated into fatty acids, at what positions in the fattyacid chain would you expect the 13C label to appear?

Treatment of a 258 mg sample of amylopectin by the methylation and hydrolysis procedure described yielded 12.4 mg of 2,3‑di‑O‑methylglucose. Determine what percentage of the glucose residues in amylopectin contained an (α1→6) branch. (Assume that the average molecular weight of a glucose residue in amylopectin is 162 g/mol and the molecular weight of 2,3‑di‑O‑methylglucose is 208 g/mol.) (   α1→6) branched glucose residues:       %
You are given 150 mL of an oil made up of a mixture of 3 fatty acids: palmitoleic acid (C 16:1 (n-7)) erucic acid (C 22:1 (n-9)) stearidonic acid (C 18:4 (n-3))   You know that the 150 mL sample of this oil was prepared by adding 60 mL of palmitoleic acid to 90 mL of a mixture of erucic acid and stearidonic acid.   Using a hydrometer you carefully measure the density of the 150 mL sample of oil and your analysis indicates that it has a density of 0.900 g/cm3.   The densities of the individual fatty acids are: palmitoleic acid = 0.894 g/cm3 erucic acid = 0.860 g/cm3 stearidonic acid = 0.9334 g/cm3   Can you determine the volumes (in mL) of erucic acid and stearidonic acid in the total volume (150 mL) of the oil mixture?
