Circle the correct answer in each sentence. Thus sugar is a (simple ; complex) carbohydrate. The linkage marked "a" is a (acetal ; hemiacetal ; acetyl ; hemiacetyl) linkage and is in the (alpha ; beta) configuration. The linkage marked "b" is a (acetal ; hemiacetal ; acetyl ; hemiacetyl) linkage.

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?

Is this the D- or L- isomer? Is this the alpha- or beta- anomer? L, alpha L, beta D, alpha D, beta
