Acetylcholinesterase is the enzyme responsible for the breakdown of acetylcholine, a neurotransmitter involved in muscle contraction and other physiological processes.

Glutamate is the primary excitatory neurotransmitter in the central nervous system, responsible for the majority of excitatory synaptic transmission.

Dopamine is a neurotransmitter involved in reward, motivation, pleasure, and motor control.

Tryptophan is the precursor molecule for the synthesis of serotonin, a neurotransmitter involved in mood, sleep, and appetite.

Dopamine decarboxylase is the enzyme responsible for the synthesis of norepinephrine from dopamine.

GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the central nervous system, responsible for reducing neuronal excitability.

Norepinephrine is a neurotransmitter involved in attention, focus, arousal, and mood.

Tyrosine is the precursor molecule for the synthesis of dopamine, a neurotransmitter involved in reward, motivation, and motor control.

Monoamine oxidase is the enzyme responsible for the breakdown of norepinephrine, a neurotransmitter involved in attention, focus, and arousal.

Serotonin is a neurotransmitter involved in mood, sleep, appetite, and memory.

Norepinephrine is a neurotransmitter involved in the fight-or-flight response, preparing the body for physical exertion and increasing alertness.

Glutamate is the precursor molecule for the synthesis of GABA, a neurotransmitter involved in inhibitory synaptic transmission.

Tryptophan hydroxylase is the enzyme responsible for the synthesis of serotonin from tryptophan.

Dopamine is a neurotransmitter involved in movement, coordination, and reward.

Endorphins are neurotransmitters involved in pain perception and reduction, producing a sense of well-being and reducing the perception of pain.
