Metabolic profiling is a branch of metabolomics that involves the systematic study of the unique chemical fingerprints that specific cellular processes leave behind. This includes the study of metabolites, small molecules produced by the chemical reactions within cells that are the intermediates and end products of metabolic pathways. Metabolic profiling can provide insights into the underlying biochemical processes in a biological system and can be used to identify biomarkers for disease, monitor treatment responses, and understand the impact of environmental factors on metabolism. This field has applications in various areas of research, including medicine, nutrition, and environmental science.
