How Hydrogen Bonding Dictates the Tertiary Structure of Proteins
Quick fact
Hydrogen bonds between side chains and the protein backbone are individually weak, yet together they act like a network of molecular 'snaps' that lock the protein into its unique 3D shape, with each protein having a specific pattern of donors and acceptors.
Why this is interesting
You know proteins are chains of amino acids, but how does a linear chain fold into a precise 3D shape that performs a specific job? The answer lies in the subtle power of hydrogen bonds.
