Small molecular metabolites (e.g., sugars, amino acids, nucleotides, and fatty acids) are the substrates and products of biochemical processes. The metabolites pictured left to right are a sugar (glucose), a nucleotide (adenosine monophosphate), and an amino acid (arginine). Metabolomics is the analysis of the metabolome—the complete set of an organism’s metabolites. Characterizing the metabolome provides a snapshot of the metabolic status of an organism and helps determine which of its enzyme-mediated reactions and biochemical pathways are active.
