Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
Dopamine Norepinephrine Serotonin. Monoamine neurotransmitters are neurotransmitters and neuromodulators that contain one amino group connected to an aromatic ring by a two-carbon chain (such as -CH 2-CH 2-). Examples are dopamine, norepinephrine and serotonin.
Serotonin pathways are thought to modulate eating, both the amount as well as the motor processes associated with eating. The serotonergic projections into the hypothalamus are thought to be particularly relevant, and an increase in serotonergic signaling is thought to generally decrease food consumption (evidenced by fenfluramine , however ...
Results showed their review of research on serotonin — the “happy hormone” — revealed “no convincing evidence that depression is associated with, or caused by, lower serotonin ...
Translation initiation is the process by which the ribosome and its associated factors bind to an mRNA and are assembled at the start codon. This process is defined as either cap-dependent, in which the ribosome binds initially at the 5' cap and then travels to the stop codon, or as cap-independent, where the ribosome does not initially bind ...
The serotonin transporter (SERT or 5-HTT) also known as the sodium-dependent serotonin transporter and solute carrier family 6 member 4 is a protein that in humans is encoded by the SLC6A4 gene. [5] SERT is a type of monoamine transporter protein that transports the neurotransmitter serotonin from the synaptic cleft back to the presynaptic ...
Serotonin has many fates in this pathway, and N- Acetylserotonin O-methyltransferase catalyzes reactions in two of these fates. The enzyme has been studied most for its catalysis of the final step of the pathway from serotonin to melatonin, but it also catalyzes one of the reactions in the many step process of serotonin → 5-Methoxy-indolacetate.
The process of amino acid building to create protein in translation is a subject of various physic models for a long time starting from the first detailed kinetic models such as [24] or others taking into account stochastic aspects of translation and using computer simulations. Many chemical kinetics-based models of protein synthesis have been ...
