What are hydrogen bonds and how do they contribute to the stability of biological molecules?
Hydrogen bonds are weak attractions between a hydrogen atom and a highly electronegative atom like oxygen or nitrogen. In biological molecules, hydrogen bonds help hold the molecules together and contribute to their stability by forming strong connections between different parts of the molecule. This helps maintain the structure and function of biological molecules like proteins and DNA.
