Metabolic Signature

Meaning

A Metabolic Signature is a distinct, measurable profile of small-molecule metabolites, such as amino acids, lipids, and organic acids, present in a biological fluid or tissue, that reflects the current physiological state or a specific pathological process within an organism. This comprehensive biochemical fingerprint, often determined via metabolomics, provides a snapshot of the body’s immediate metabolic activity and its response to genetic factors, environmental influences, and hormonal signaling. Analyzing this signature offers valuable insights for personalized medicine, risk stratification, and understanding the progression of metabolic disorders.
