Serotonin - Definition

July 2017


Definition


Serotonin is a neuro-transmitter, a substance enabling the transfer of nerve impulses between neurons. The full name of this molecule is 5 hydroxytryptamine (5-HT). Serotonin is derived from an amino acid called tryptophan, an essential element in the body's building of proteins. This molecule also plays a similar role to that of hormones as it induces certain actions, notably by regulating certain moods. Some types of medication impact on the quantity of serotonin in the body, thus positively influencing conditions of depression.
