Metabolite profiling, also known as metabolomics, is the comprehensive study of small molecules, or metabolites, within cells, tissues, or organisms. These metabolites are the intermediates and products of metabolic processes and provide a snapshot of the physiological state of a biological system. In the context of Bioanalytical Sciences, metabolite profiling enables researchers to gain insights into biochemical pathways, disease mechanisms, and the effects of drugs or other interventions.
