The study, “Parallel Pathways for Serotonin Biosynthesis and Metabolism in C. elegans,” challenges the existing knowledge of how serotonin is produced and what happens to the neurotransmitter ...

The metabolism of tryptophan within the human body can follow one of two pathways, toward serotonin or toward production of kynurenine, a substance that plays a role in niacin production.

Tryptophan is a precursor of serotonin, the neurotransmitter responsible for mood. A new intermediate step and unexpected enzymatic activity in a metabolic pathway in the body, which could lead to ...

which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain, according to a recent study ...

Selective serotonin reuptake inhibitors (SSRIs ... These studies have pointed to several metabolites on the tryptophan metabolic pathway as potential contributing factors to whether patients ...

Scientists are only just now learning about the roles these intestinal serotonin secretions play in regulating everything from our gastrointestinal movements, to our general metabolism.

Research over the last decade has focused on understanding the shift in calcium metabolism, with an emphasis on the relationship of serotonin with calcium during the transition period and lactation.

This suggests that there are other serotonin-producing nerve pathways in the brain associated with the feelings of reward and aversion. To further study the reward and aversion nerve pathways of ...
