ChEBI

ChEBI (Chemical Entities of Biological Interest) is a free online database that catalogs and organizes chemical substances relevant to biology, such as drugs, nutrients, and metabolites. It provides detailed information about each compound's structure, properties, and biological roles, helping researchers understand how chemicals function in living systems. By standardizing data and relationships between compounds, ChEBI supports scientific studies in biochemistry, pharmacology, and related fields, fostering better communication and discovery in the biological sciences.
