Applications Of NMR In Biology

Applications Of NMR In Biology

Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an analytical tool. F. Bloch and E. Purcell formulated NMR in 1946 and won the 1952 Nobel Prize in Physics for their work. Biological macromolecules such as proteins, nucleic acids, lipids, and organic molecules including pharmaceutical compounds, can be studied using this versatile tool that exploits the magnetic properties of certain nuclei.

¹H NMR Signal Integration: Overview

¹H NMR Signal Integration: Overview

The intensity of a signal, which can be represented by the area under the peak, depends on the number of protons contributing to that signal. The area under each peak is shown as a vertical line called an integral, with the integral value listed under it, as seen in the proton NMR spectrum of benzyl acetate. Each integral value is divided by the smallest integral value to obtain the ratio of the number of protons producing each signal. The ratio reveals the relative number of protons and not...

Tandem Mass Spectrometry

Tandem Mass Spectrometry

Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and signal-to-noise ratio for the analyte. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.
Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called collision-induced...

Mass Spectrometry: Complex Analysis

Mass Spectrometry: Complex Analysis

Mass spectrometry is an important technique for the identification of pure compounds. However, it has some limitations for the analysis of complex mixtures, often due to excessive fragmentation making the spectrum too complicated to decipher. Mass spectrometry can be combined with suitable separation methods in sequence, forming hyphenated methods, which are useful in the analysis of complex mixtures.
GC–MS is a powerful hyphenated method commonly used in forensics and environmental...

Nuclear Magnetic Resonance (NMR): Overview

Nuclear Magnetic Resonance (NMR): Overview

Nuclear magnetic resonance (NMR) is a phenomenon exhibited by certain nuclei that can absorb characteristic radio frequency radiation under certain conditions. NMR has been extensively applied in molecular spectroscopy and medical diagnostic imaging. In both these applications, the molecule or subject under study is placed in a magnetic field and irradiated with radio frequency energy.
NMR spectroscopy generates a spectrum where the characteristic absorption frequencies of the sample are...

NMR Spectrometers: Overview

NMR Spectrometers: Overview

NMR spectrometers consist of a strong magnet, a radiofrequency transmitter, and a detector attached to a computer console for recording spectra of samples containing NMR-active nuclei. In first-generation NMR instruments called continuous-wave spectrometers, the resonance frequencies of the nuclei are determined by frequency-sweep or field-sweep methods. The magnetic field strength is fixed and the rf signal is swept in the former, while the radiofrequency signal is fixed and the magnetic field...

Background:

Metabolomics utilizes Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) spectroscopy for metabolite analysis.
MS offers high sensitivity but is destructive with limited structural data; NMR is non-destructive, enabling structural elucidation and quantification.
Complementary strengths of MS and NMR necessitate integrated approaches for comprehensive metabolomic profiling.

Purpose of the Study:

To review data fusion (DF) methodologies integrating NMR and MS data in metabolomics over the last decade.
To analyze various fusion techniques, statistical methods, and their applications in metabolomic studies.
To highlight the increasing significance of DF in advancing metabolomic research.

Main Methods:

Comprehensive literature search across SciFinder, Scopus, and Clarivate Web of Science databases.
Analysis of studies employing data fusion strategies for NMR and MS data in metabolomics.
Systematic review of fusion techniques, statistical models, and their reported outcomes.

Main Results:

Data fusion (DF) strategies are increasingly adopted to leverage complementary NMR and MS data in metabolomics.
DF enhances the comprehensiveness of metabolomic analyses by integrating distinct data types.
Reviewed methodologies demonstrate the utility of DF across diverse biological matrices, including clinical, plant, and food samples.

Conclusions:

Data fusion is crucial for maximizing the information gained from NMR and MS in metabolomics.
Integrating NMR and MS data provides a more holistic view of metabolic pathways and biochemical processes.
The application of DF in metabolomics is expanding, offering powerful insights into complex biological systems.
