Determine the branch points and reducing ends of amylopectin. A 0.5g sample of amylopectin was analyzed to determine the fraction of the total glucose residues that are branch points in the structure. The sample was methylated and then digested, yielding 50 μmol of 2,3-methylglucose and 0.4 μmol of 1,2,3,6-tetramethyl glucose. (MWglucose = 162 g/mol, minus H2O) What fraction of the total residues are branch points? How many reducing ends does the amylopectin have?
When some sugars dissolve in water they spontaneously undergo changes in optical rotation called mutarrotation. The Mutarrotation of D-glucopyranose is catalyzed by acid and bases. 2-Hydroxypyridine is a more effective catalyst than phenol and pyridine for this reaction because: a.Both oxygen and N in 2-hydroxypyridine act as bases increasing the rapid interconversion of sugar b. The OH of 2-hydroxypyridine serves as the base while the current N as the acid. c. 2-hydroxypyridine acts both as a base to remove the proton from the hydroxyl group in the hemiacetal and as an acid to provide a proton to the oxygen in the hemiacetal. d.Phenol and pyridine are very expensive.

Hanus reagent: react with saturated lipid bondc. Reflux set-up: hasten reactiond. Blank titration: determine total mol of KOH2. A triacylglycerol (Sample X) was subjected to saponification analysis. 1.1 grams of thesample was refluxed with 5% alcoholic KOH and the refluxed solution was titrated with 17.2 mLof 0.44 M HCl titrant. The blank solution was titrated with 25.6 mL of the titrant.i. What is the saponification number of the sample? ii. Which of the following could be the identity of the sample? Show solutions pls a.
