  1. 1. Was healthy people co Actually Worth The $?platforms currently doing work in metabolomic research is summarized in this chapter alongwith all the required computer software. The examples provided in this chapter demonstratethat metabolomics is playing an extremely important role in nutritional research, beinga dietary assessment tool, a predictive tool for nutritional effects (nutrimetabonomics) with 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 would be to profi le the whole complement with thesmall- molecule metabolites in our bodies. Numerous defi -nitions for metabolomics are located in the literature,but among the simplest and many succinct is %u201C the excellentand quantitative analysis coming from all metabolites %u201D (Fiehn,2001 ). Note that the bradenton area of scientific studies are sometimes referredto as metabonomics that terms have become interchangeable.You will find theres similarly many defi nitionsof the constitutes a metabolite. Inside the broadestsense, total metabolite pool, or metabolome, includes thecomplete complement of endogenous metabolites alsoas metabolites produced by diet, medication, environmentalexposures, as well as the gut microbiome (Dunn, 2008 ).Estimates of the size of the metabolome will also be susceptible to

The Human Metabolome Databasehas been called the blueprint in the human metabolome,within a fashion analogous towards the Human GenomeProject (Wishart et al ., 2009 ). This database currently(left) shows the number of publications during the last 10years in genomics, proteomics, and metabolomics. Theearliest are employed in metabolomics focused heavily on toxicologystudies. The development of metabolomics within thisarea is the main topic of a fantastic review by Robertsonet al . (2011) . Nutrition scientists realized the potentialfor metabolomics somewhat later. Figure 4.2 (right)compares the increase of the complete fi eld of metabolomicsusing the applications specifi cally innutrition. Much of this delay might be mainly because thatnutritional interventions are nearly always destined to bemore subtle, yielding smaller metabolic perturbationsthan pharmaceutical interventions. As the technologiesutilized to profi le the metabolome have matured, the abilityto detect more subtle perturbations over the standardvariability thats expected inside the population has

The concentrationranges of metabolites span over the dozen ordersof magnitude with compounds including glucose within the millimolarrange in blood, and compounds for example someeicosanoids down within the femtomolar range. The differencesin proportions and polarity also present challenges for differentplatforms. Not one analytical platform can measurethe whole metabolome, so metabolomics studies shouldchoose the optimal technology or mixture of technologieseverslim
