Nuclear magnetic resonance based metabolomics and liver diseases: Recent advances and future clinical applications

Figure 1 “Omic” techniques. Schematic representation in biological system: Each functional level from the DNA, RNAs, Proteins and metabolites who constitute respectively the genome, transcriptome, proteome and metabolome, have bidirectional flow of information and complex interactions together and with the environment (diseases, drug, lifestyle, genre, habit, diet, etc.). Those interactions produce the phenotype that represents the final output of the system measured in metabolomics.
