Question

Select all that apply. Name three interactions that stabilize the shape of a soluble, globular protein and identify the structural features that allows for these interactions. A. disulfide linkages between the ends of two cysteine side chains B. salt links between -coo and -NH groups 3 IM C. disulfide bonding between C o of one peptide bond and N-H of another V D. hydrogen bonding between the ends of two cysteine side chains E. peptide bonding between the ends of two cysteine side chains F. peptide bonds between -Coo and -NH 3 groups L G. hydrogen bonding between C-o of one peptide bond and N-H of another M H. dispersion forces between -Coo and 3 groups L I. dispersion forces between C O of one peptide bond and N-H of another J. salt links between C o of one peptide bond and N-H of another

Explanation / Answer

Interactions responsible for the stability of globular proteins are:

1. Polar and non-polar interactions

2. Hydrogen bonding

3. Ionic interactions

4. Disulphide bonds: S=S double bond formation in cysteine group

The structural features thqat allows for the above interactions:

A. Disulphide linkages between the ends of two cysteine side chains

B. Salt link between -COO- and -NH3+

G. Hydrogen bonding between C=O of one peptide bond and N-H of another
