Metabolomics is a study of metabolites in a biological sample all at once (high-throughput analysis) using advanced analytical tools such as GC-MS, LC-MS, or NMR. These metabolites are the end products of gene expression, which closely reflect the phenotype. Metabolomics study provides insight understandings about the life sciences and helps answer biological questions, leading to the development of many innovations related to health. Nowadays, metabolomics technology is being applied in many fields of study, such as medical, pharmaceuticals, food and nutrition, agriculture, and environmental science.
