Figure 2 From A Guide To The Identification Of Metabolites In Nmr Basedођ With both nmr and ms based detection technologies, the identification of the metabolites in the biological sample remains a significant obstacle and bottleneck. this article provides guidance on methods for metabolite identification in biological fluids using nmr spectroscopy, and is illustrated with examples from recent studies on mice. This guide aims to provide an insight into the methodologies that can be used for nmr based metabolite identification in the course of a metabonomics project. it is assumed that the reader is familiar with the basics of nmr spectroscopy: many excellent books on the topic are available [35–38] .
Figure 1 From A Guide To The Identification Of Metabolites In Nmr Basedођ The unit describes an optimized metabolite extraction protocol, followed by implementation of nmr experiments and quantification strategies using the so‐called “targeted profiling” technique, which relies on an underlying basis set of metabolite spectra acquired under similar conditions. 348 o t h e ri na ne f f e c tc a l l e d ‘ roo fi ng ’.t h i si sw e l li l l u s t r a t e di nt h es p e c t r ao f 349 the two, non equivalent methylene protons in citric acid shown in.

(a. Nuclear magnetic resonance (nmr) spectroscopy is a major analytical method used in the growing field of metabolomics. nmr is relatively less sensitive relative to mass spectrometry, the other major analytical platform in the metabolomics field. however, numerous characteristics of nmr including its high reproducibility and quantitative. In this review, we will focus on several nmr strategies of interest in studying metabolism: i) metabolomics analyses; ii) metabolite identification and structure elucidation; iii) quantification (qnmr) of metabolites; iv) the use of stable isotopes in metabolism studies; and v) metabolite protein interactions, figure 1.
