Ionic bonds, hydrogen bonds, covalent bonds, dipole-dipole and
van der Waals dispersion forces are all involved in maintaining
the:
A. cis-formation of long-chin fatty acids
B. stability of phospholipids
C. tertiary structure of proteins
The correct option is C. tertiary structure of proteins
EXPLANATION: Tertiary structure of protein is the 3 dimensional shape of a protein where the secondary structures are folded resulting into an overall 3 dimendional shape. The main forces that gives stability to the tertiary structure of proteins are hydrogen bonding, electrostatic interactions (ionic bonds) dispersion forces, dipole dipole forces and covalent bonds like hydrophobic and hydrophilic interactions
