The Dairy Molecule Database (DMD) is a structured research repository developed to support the largest milk-molecule profiling study conducted in the United States to date. The platform provides organized access to molecules identified in whole milk samples alongside associated omics datasets. It integrates a searchable frontend with a programmatic API to enable structured exploration, comparison, and retrieval of molecular data. Designed to support rigorous scientific analysis, DMD facilitates reproducible investigation of milk-related biochemical composition.
