Metabolomic applications in nutritional research are increasing rapidly, primarilybecause metabolomics and nutrition address precisely the same questions in metabolism,metabolicperturbations, oxidation, and infl ammation as primary processes that maintain human health.Analytical and profi ling techniques in metabolomics also are evolving rapidly, along with theanalyticalplatforms currently used in metabolomic research is summarized on this chapter alongusing the required human resources software. The examples provided with this chapterdemonstratethat metabolomics is playing an ever more part in nutritional research, beinga dietary assessment tool, a predictive tool for nutritional effects (nutrimetabonomics) as wellas anepidemiological profi ling tool, which involve gut microbial %u2013mammalian co -metabolism.of genomics is usually to study all of our genes, so the objective ofmetabolomics is always to profi le the entire complement with thesmall- molecule metabolites inside our bodies. Numerous defi -nitions for metabolomics can be found in the literature,but one of many simplest and most succinct is %u201C the greatand quantitative analysis coming from all metabolites %u201D (Fiehn,exposures, along with the gut microbiome (Dunn, 2008 ).Estimates of the size of the metabolome may also be susceptible todebate, with estimates exceeding 10 000 if dietary components
and many types of combinatorial possibilities of long chain fattyacids are viewed. A Persons Metabolome Databasemay be described as the blueprint with the human metabolome,in the fashion analogous on the Human GenomeProject (Wishart et al ., 2009 ). This database currentlycontains extensive clinical and chemical data for over7900 compounds (HMDB version 2.5).Being the newest from the post - genomics technologies,metabolomics is within a fast growth phase. Figure 4.2(left) shows the number of publications over the last 10years in genomics, proteomics, and metabolomics. Theearliest be employed in metabolomics focused heavily on toxicologystudies. The development of metabolomics with thisarea is the topic of a great review by Robertsonet al . (2011) . Nutrition scientists realized the possibilityfor metabolomics somewhat later. Figure 4.2 (right)compares the expansion of the overall fi eld of metabolomicswhile using applications specifi cally innutrition. Part of this delay might be simply because thatnutritional interventions are almost always likely to bemore subtle, yielding smaller metabolic perturbationsthan pharmaceutical interventions. Since the technologies
utilized to profi le the metabolome have matured, the abilityto detect more subtle perturbations over the standardvariability that is certainly expected from the population hasincreased. On this chapter troubles of nutritionalFIG. 4.1 Relationship between your genome, proteome, and metabolome.Genome Proteome MetabolomeExactly what do happen Whats so that it is happen What is actually happeningmetabolomics will probably be described along with current waysby which nutritional scientists can overcome these challengesto achieve more information from the downstream metabolicconnection between nutrition.Measuring the MetabolomeThe vast chemical diversity from the metabolome presents atremendous challenge if the goal is usually to present an unbiasedand quantitative measurement famous it. The concentrationranges of metabolites span over a dozen ordersof magnitude with compounds including glucose inside the millimolarrange in blood, and compounds including someeicosanoids down from the femtomolar range. The differencesin dimensions and polarity also present challenges for differentplatforms.
