Explore its structure
Choose a part to light it up.
A C=O with a nitrogen on one side and an oxygen on the other, half amide and half ester. Water splits it more slowly than it splits an ester.
From: standard chemistry.
A C=O bonded to a nitrogen, the same link that joins amino acids in a protein. It is sturdy, and its nitrogen is not a base the way an amine's is.
From: standard chemistry.
A nitrogen bonded to three carbons, with no hydrogen of its own. Its spare pair of electrons can still pick up a hydrogen ion, so a tertiary amine is a base.
From: standard chemistry.
