Metabolites, Volume 12, Issue 1

January 2022 - 88 articles

Cover Story: TrpNet is a comprehensive database and analytics platform to help researchers to understand tryptophan metabolism within the context of host and gut microbiome co-metabolism. It currently contains 108 tryptophan metabolites and 130 reactions across 5270 genome-scale metabolic models (GEMs), including 1246 and 88 bacterial species identified from the human and mouse gut microbiome, respectively. Users can browse, search, and highlight the tryptophan metabolic pathway, as well as predict tryptophan metabolites from a given taxonomy profile using Bayesian logistic regression models. TrpNet was able to better predict alterations in indole derivatives compared to other established methods based on two gut microbiome metabolomics studies. View this paper.

Stability of Wheat Floret Metabolites during Untargeted Metabolomics Studies

  • Kristin Whitney,
  • Gerardo Gracia-Gonzalez and
  • Senay Simsek

11 January 2022

A typical metabolomic analysis consists of a multi-step procedure. Variation can be introduced in any analysis segment if proper care in quality assurance is not taken, thus compromising the final results. Sample stability is one of those factors. Al...
