Chapter 10: Q19E (page 585)

Proteins are chains of amino acids that can form in a variety of arrangements, one of which is a helix. What kind of IMF is responsible for holding the protein strand in this shape? On the protein image, show the locations of the IMFs that hold the protein together:

Short Answer

Expert verified

\({\rm{H - }}\)Bonding is the main intermolecular force. And it is somewhere between \({\rm{N - H}}\) and \({\rm{C = O}}\).

Step by step solution

01

Definition of Intermolecular force

Intermolecular forces, often called as IMF, are the attractive and repulsive forces that happens between the molecules of a substance. These forces passes the interactions between individual molecules of a substance.

02

Determining the IMF

\({\rm{H - }}\)Bonding is the main intermolecular force that holds the DNA strands together. And it's somewhere between \({\rm{N - H}}\) and \({\rm{C = O}}\).
