Options

  1. AIn alanylglycylleucylalanylvaline the number of peptide linkages is:
  2. BIn alanylglycylleucylalanylvaline the number of peptide linkages is:
  3. CIn alanylglycylleucylalanylvaline the number of peptide linkages is:
  4. DIn alanylglycylleucylalanylvaline the number of peptide linkages is:

Correct answer

A. In alanylglycylleucylalanylvaline the number of peptide linkages is:

Step-by-step solution

A and D cannot be oxidised by bromine water as they do not have hemiacetal linkage. The acid hydrolysis of A leads to a laevorotatory solution. A is sucrose which is dextrorotatory, on acid hydrolysis gives mixture of α\alpha-D-glucopyranose and β\beta-D-fructofuranose, the mixture is laevorotatory.

A disaccharide X cannot be oxidised by bromine water. The acid hydrolysis of X leads to a laevorotatory solution. The
