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.

For many years, researchers thought that serotonin was made in C. elegans by one specific molecular pathway, and that serotonin was then quickly degraded. Schroeder's team and colleagues at ...

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 ...

Serotonin is synthesized from the amino acid L-tryptophan via a short metabolic pathway that involves two major enzymes. These enzymes are: Tryptophan hydroxylase (TPH) Amino acid decarboxylase ...

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.
