proteins
a)Protein denaturation involves cleavage of its peptide bonds.
b)Denaturation of an enzyme will cause a loss of its catalytic activity.
c)A denatured protein has a different tertiary structure than its native state.
d)Denaturation and digestion refer to the same process.
e)A competetive enzyme inhibitor acts by denaturing the enzyme.
f)A denatured protein has a different primary structure than its native state.
Homework Answers
true : b, c
Denaturing destroys the secondary and tertiary structure. Primary
structure remains unaffected. Loss of tertiary structure causes
loss of function of the protein.

pKa perturbations: A water-soluble globular protein has 2 aspartic acid residues in different parts of the tertiary structure. Both are almost completely buried in the interior of the native protein. (10 points) The first Asp residue has a pKa of 7.4 in the native state, but a pKa of 4.4 in the denatured state. Explain the difference in pKa between the two states (10 points) The other Asp residue, also buried in the native structure, has a pKa of 2.4...
