Name | Molecular Formula | Function | Description | Source |
|---|---|---|---|---|
C₇H₁₆NO₂⁺ | Neurotransmitter | Primary neurotransmitter at neuromuscular junctions and in the parasympathetic nervous system. Essential for muscle contraction, memory, and learning. | ||
C₁₀H₁₃N₅O₄ | NeuromodulatorNucleoside | Building block of DNA/RNA and ATP. Acts as a sleep-promoting neuromodulator that accumulates during wakefulness and creates sleep pressure. | ||
C₉H₁₃NO₃ | NeurotransmitterGeneral Hormone | "Fight or flight" hormone released by adrenal glands. Increases heart rate, blood pressure, and energy availability during stress or excitement. | ||
C₁₅₈H₂₅₁N₃₉O₄₆S | NeuropeptideGeneral Hormone | Natural opioid peptides that reduce pain perception and create feelings of euphoria. Released during exercise, stress, and pleasure. | ||
C₂₁H₃₀O₅ | Steroid Hormone | Primary stress hormone that regulates metabolism, immune response, and blood pressure. Follows circadian rhythm with peak levels in morning. | ||
C₈H₁₁NO₂ | Neurotransmitter | Key neurotransmitter for reward, motivation, and motor control. Central to pleasure pathways and implicated in addiction and Parkinson's disease. | ||
C₄H₉NO₂ | Neurotransmitter | Primary inhibitory neurotransmitter in the brain. Reduces neuronal excitability and promotes calm, relaxation, and sleep. | ||
C₅H₉N₃ | NeurotransmitterLocal Hormone | Involved in immune responses, allergic reactions, and wakefulness. Also regulates stomach acid production and acts as a neurotransmitter. | ||
C₁₃H₁₆N₂O₂ | General Hormone | Sleep-regulating hormone produced by the pineal gland. Released in darkness to promote sleepiness and regulate circadian rhythms. | ||
C₁₉₀H₂₈₉N₅₅O₅₇ | Neuropeptide | Potent appetite stimulant and stress response modulator. One of the most abundant neuropeptides in the brain, involved in feeding behavior and anxiety. | ||
C₈H₁₁NO₃ | NeurotransmitterGeneral Hormone | Neurotransmitter involved in attention, arousal, and stress response. Also acts as a hormone when released by adrenal glands. | ||
C₄₃H₆₆N₁₂O₁₂S₂ | NeuropeptideGeneral Hormone | "Love hormone" that promotes bonding, trust, and empathy. Essential for childbirth, lactation, and social relationships. | ||
C₁₀H₁₂N₂O | Neurotransmitter | Regulates mood, sleep, appetite, and digestion. Low levels associated with depression; most of body's serotonin is produced in the gut. | ||
C₆₃H₉₈N₁₈O₁₃S | Neuropeptide | Pain transmission peptide that carries pain signals from peripheral nerves to the central nervous system. Also involved in inflammation and mood regulation. | ||
C₄₆H₆₄N₁₄O₁₂S₂ | NeuropeptideGeneral Hormone | Antidiuretic hormone that regulates water retention in kidneys. Also influences social behavior, pair bonding, and aggression. |
