Metabolomics, a subset of systems biology, is crucial for unraveling the complex metabolic pathways of leguminous plants, specifically those in the Fabaceae family. By utilizing the NPASS (Natural Products Activity and Species Source) database at https://bidd.group/NPASS/index.php, researchers can delve into the metabolomic profiles of legumes. This platform aids in identifying and characterizing metabolites, providing a comprehensive understanding of the distinctive metabolic mechanisms within the legume kingdom. The NPASS database serves as a valuable resource for researchers exploring the metabolic intricacies of leguminous plants, contributing to our broader knowledge of plant metabolism.
