*Hydrogen Bonds, the weakest of bonds, are attractive interactions between an electronegative atom and hydrogen. Electronegative atoms are atoms that have high electron density. They are strong atoms that pull electrons towards them from weaker/low electron density atoms, such as hydrogen. When the electronegative atom pulls the electrons, it leaves the other atom with a slightly positive charge.  Water is the most common example of hydrogen bonding. The water molecule chemical formula is H2O. The highly electronegative oxygen pulls the hydrogen closer by attracting hydrogen’s electrons and allowing the formation of a water droplet. The electronegative atoms allow for the droplet to be held together instead of spreading. In this representation the hydrogen bonds are represented as yellow-dashed lines. The hydrogen bonds are important to the stability of the secondary structures.
