Question

a) Write Haworth structure for maltose.
b) What is meant by denaturation of proteins? Which level of structure remains intact during denaturation of globular protein?
c) Name the base present only in DNA but not in RNA.

Answer 1

a) The Haworth structure for maltose is as shown.
b) Denaturation of proteins is irreversible precipitation due to heating the protein with alcohol, concentrated inorganic acids or by salts of heavy metals.
Primary structure remains intact during denaturation of globular protein.
c) The base present only in DNA but not in RNA is $uracil$.
