Neurotransmitters

Neurotransmitters are peptides (opioids), monoamines (serotonin, dopamine), amino acids (glutamine), or other small molecules (GABA, acetylcholine, ATP, NO). They are stored and released by neurons to effect signals via binding to receptors on other neurons. These signals can be disrupted or enhanced in disease, and they can be modulated by drugs. Focus Biomolecules offers agonists, antagonists, precursors, and metabolites for neurotransmitter research.
