Serotonin

 

Serotonin is a chemical produced by nerve cells. It sends signals between your nerve cells. Serotonin is found mainly in the digestive system, although it is also found in blood platelets and throughout the central nervous system. Serotonin is made from tryptophan, an essential amino acid. This amino acid must enter your body through your diet and is commonly found in foods such as nuts, cheese, and red meat. A deficiency in tryptophan can lead to a drop in serotonin levels. This can lead to mood disorders, such as anxiety or depression. Serotonin or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. It has a popular image as a contributor to feelings of well-being and happiness, although its actual biological function is complex and multifaceted, modulating cognition, reward, learning, memory and many physiological processes such as vomiting and vasoconstriction. Biochemically, the indoleamine molecule derives from the amino acid tryptophan, via hydroxylation (limiting) from position 5 on the cycle (forming the intermediate 5-hydroxytryptophan), then decarboxylation to produce serotonin. Serotonin is mainly found in the enteric nervous system located in the gastrointestinal tract (gastrointestinal tract).
