Metabolomics

Definition

Metabolomics is the comprehensive study of metabolites, which are small molecules involved in metabolic processes, within a biological system. It provides insights into the biochemical activities occurring in cells and tissues by analyzing the profiles of metabolites, allowing for a better understanding of metabolic networks and their interactions. This field is essential for studying how organisms respond to various environmental changes and can reveal important information about disease mechanisms, drug responses, and nutritional effects.
