Explore its structure
Choose a part to light it up.
A carbon carrying both a C=O and an O-H, written COOH. In water it gives up that hydrogen, which is what makes the molecule an acid.
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.
Rings joined where they share atoms, or a single ring standing alone. Atoms in a ring are held in place, so this part keeps its shape while chains around it can bend.
From: standard chemistry.
