Metabolites are small molecules that are produced as products of metabolism within living organisms. These molecules serve as intermediates in biochemical pathways, as well as signaling molecules and energy sources. Metabolites can be found in various biological fluids, tissues, and cells, and play essential roles in maintaining cellular function and overall health. Studying metabolites can provide valuable insights into various biological processes, disease mechanisms, and potential therapeutic targets. Metabolomics is the study of metabolites and their abundance within biological systems, and is a growing field of research with applications in personalized medicine, drug development, and understanding the impact of environmental factors on health.
