&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insulin is able to pair-up with itself and form a dimer by forming hydrogen bonds between the ends of two B-chains. These <scene name='User:Whitney_Stoppel/sandbox1/Insulin_dimer/2'>hydrogen bonds</scene> are shown above in white. Then, 3 dimers can come together in the presence of zinc ions and form a hexamer.

It is believed that the hydrophobic sections on the B-chain cause insulin aggregation which initially caused problems in the manufacture and storage of insulin for [[Pharmaceutical_Drugs#Treatments|pharmaceutical use]].
