Did you mean Hydrogen Bonds?

GlossaryHydrogen Bonds

weak attractions between hydrogen and electronegative atoms

Hydrogen bonds are a type of weak chemical bond that occurs when a hydrogen atom, which is covalently bonded to a more electronegative atom like oxygen or nitrogen, experiences an attraction to another electronegative atom nearby. These bonds are crucial in many biological processes, including the structure of DNA and the properties of water, and they play a significant role in the secondary and tertiary structures of proteins, including those found in hair.
