Metabolomics: opening another window into aging.

Metabolomics is based on the simultaneous analysis of multiple low-molecular-weight metabolites from a given sample. As such, metabolomics seeks the most up-to-date information about the state of interaction between an organism and its environment. The ability to use metabolomics approaches for classification and mechanistic studies may influence and augment our ability to study and address the aging process scientifically and clinically.
