Eosinophilia–myalgia syndrome is a rare, sometimes fatal neurological condition linked to the ingestion of the dietary supplement L-tryptophan. [1] [2] The risk of developing EMS increases with larger doses of tryptophan and increasing age. [3]
Tryptophan (symbol Trp or W) [3] is an α-amino acid that is used in the biosynthesis of proteins.Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent.
[8]: 327–328 Multiple epidemiological studies [7] [9] [10] traced an outbreak of eosinophilia-myalgia syndrome (EMS) to L-tryptophan supplied by Showa Denko, which resulted in 37 deaths. [11] [12] It was further hypothesized that one or more trace impurities produced during the manufacture of tryptophan may have been responsible for the EMS ...
But, perhaps the most common cause for eosinophilia is an allergic condition such as asthma. In 1989, contaminated L-tryptophan supplements caused a deadly form of eosinophilia known as eosinophilia-myalgia syndrome, which was reminiscent of the toxic oil syndrome in Spain in 1981.
α-Methyltryptophan (αMTP or α-MTP) is a synthetic tryptamine derivative, an artificial amino acid, and a prodrug of α-methylserotonin (αMS). [1] [2] [3] It is the α-methylated derivative of tryptophan, while αMS is the α-methylated analogue of serotonin.
Kynurenic acid (KYNA or KYN) is a product of the normal metabolism of amino acid L-tryptophan. It has been shown that kynurenic acid possesses neuroactive activity. It acts as an antiexcitotoxic and anticonvulsant, most likely through acting as an antagonist at excitatory amino acid receptors. Because of this activity, it may influence ...
L-Tryptophan, a precursor of serotonin and melatonin and an example of a monoamine precursor.. Monoamine precursors are precursors of monoamines and monoamine neurotransmitters in the body.
Aromatic L-amino acid decarboxylase is active as a homodimer. Before addition of the pyridoxal phosphate cofactor, the apoenzyme exists in an open conformation. Upon cofactor binding, a large structural transformation occurs as the subunits pull closer and close the active site. This conformational change results in the active, closed ...
