Peringatan Keamanan

Queuine is a natural biochemical that can be found endogenously in the human body A173830, A173833, A173851. Although certain studies on mouse models have shown that a deficiency in the agent can have fatal consequences A173830, A173833, A173851, data regarding toxicity or overdosage of queuine is not readily available or accessible.

Queuine

DB14732

small molecule experimental nutraceutical

Deskripsi

Queuine is a derivative of 7-Deazaguanine. Bacteria possess the exclusive ability to synthesize queuine, which is then salvaged and passed on to plants and animals. Quantities of queuine have been found in tomatoes, wheat, coconut water, and milk from humans, cows, and goats. Humans salvage and recover queuine from either ingested food or the gut flora. All eukaryotic organisms, including humans, transform queuine to queuosine by placing it in the wobble position (anticodon) of several tRNAs including aspartic acid, asparagine, histidine, and tyrosine. Endogenously, it has been determined that queuine contributes to generating various important biochemicals like tyrosine, serotonin, dopamine, epinephrine, norepinephrine, nitric oxide, lipids, and others A173830, A173833, A173851.

Absorpsi

Humans recover queuine from either ingested food or the gut flora A173830, A173833, A173851. The proportion of queuine salvaged and absorbed from the normal turnover process of human microbiota has not yet been determined, but it may be significant given the number of microorganisms in the human gastrointestinal tract A173830. Furthermore, it is believed that there may exist a dedicated transporter for queuine, considering various purines, purine-derivatives and base analogs are incapable of affecting queuine transport in competitive uptake experiments A173830, A173833.

Metabolisme

Data regarding the metabolism of queuine is not readily available or accessible.

Rute Eliminasi

Data regarding the route of elimination of queuine is not readily available or accessible.
