Why are hydrogen bonds important in biology?

Hydrogen Bonds:

Hydrogen bonds are forces that hold molecules to each other. As the name implies, these bonds involve hydrogen covalently bonded to nitrogen, oxygen, and fluorine. These bonds are very polar, meaning most of hydrogen's electrons are pulled away. The positively-charged hydrogen on one molecule can then bind to the negatively-charged nitrogen, oxygen, or fluorine on another molecule.
