Metabolome

Definition

The metabolome refers to the complete set of small molecule metabolites found within a biological sample, such as a cell, tissue, or organism, at a specific time under particular conditions. This dynamic collection of metabolites provides insight into the metabolic state and physiological processes of an organism, making it essential for understanding cellular functions, interactions, and responses in various biological contexts.
