Metabolomics is the comprehensive and quantitative analysis of multiple metabolites in biological samples.

Metabolome is the complete set of small-molecule metabolites found within a single biological
system

Targeted metabolomics aims to quantify a set of predefined metabolites in a sample.

Untargeted (sometimes termed ‘global’) metabolomics aims to quantitatively measure the levels of all metabolites.

Metabolomics Biomarkers may be useful for four main purposes:

1) controlled trials
2) dietary intakes in observational studies
3) explaining the biological effects of the diet
4) characterizing a specific genotype or phenotype

Alignment tools for this include:
mz-Mine
XCMS (R code script), and Metalign
