Explore its structure
Choose a part to light it up.
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.
Fluorine, chlorine, bromine or iodine bonded to carbon. Each pulls electrons toward itself, and each is larger than the hydrogen the carbon would otherwise carry.
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.

Risperidone blocks the dopamine D2 receptor outright, while aripiprazole is a partial agonist that switches it on slightly, so it raises prolactin less.
