RT-Tranformer: Retention Time Prediction for Metabolite Annotation to Assist in Metabolite Identification [PDF]

, 2023
Liquid chromatography retention times (RTs) prediction can assist in metabolite identification, which is a critical task and challenge in non-targeted metabolomics.However, different chromatographic methods (CM) may result in different RTs for the same ...

Metabolite analysis of Escherichia coli in response to changes in oxygen levels [PDF]

, 2013
E. coli is a versatile bacterium that has three metabolic modes: aerobic, anaerobic and fermentation. The major environmental factor that controls the switching between these metabolic modes is oxygen availability. E.

Understanding and Classifying Metabolite Space and Metabolite-Likeness

PLoS ONE, 2011
While the entirety of 'Chemical Space' is huge (and assumed to contain between 10(63) and 10(200) 'small molecules'), distinct subsets of this space can nonetheless be defined according to certain structural parameters. An example of such a subspace is the chemical space spanned by endogenous metabolites, defined as 'naturally occurring' products of an
