Hydrogen bonds hold water molecules together. Hydrogen bonds are very strong, which accounts for the high boiling point of water (100˚C, 212˚F), and its ability to remain liquid water over such a huge range of temperatures.
The negative oxygen and positive hydrogen in water form hydrogen bonds with each other.

The atomic covalent bonds
Peptide bonds hold amino acids together in a protein chain. Peptide bonds form through a condensation reaction between the carboxyl group of one amino acid and the amino group of another amino acid, releasing a water molecule in the process.
It's simply just energy.
Hydrogen bonds hold the nitrogenous bases together in a strand of DNA. These bonds form between complementary base pairs: adenine with thymine, and guanine with cytosine.
