Neuropeptides are the largest type of neuromodulator, consisting of chains of amino acids that can be quite long. Examples include endorphins, substance P, and neuropeptide Y. The other options listed are smaller molecules, such as nitric oxide, which consists of only one atom, or dopamine, which is a small molecule composed of a handful of atoms.
