metabolomi

Metabolomi is a term that appears in some scientific writings as a plural form intended to refer to multiple metabolomes—the complete set of small-molecule metabolites present in a biological sample. In standard English, the conventional plural is metabolomes; metabolomi is less common and often arises from non-English sources or as a neo-Latin plural in specific contexts.

Definition and scope: A metabolome describes the full complement of metabolites detectable in a given organism, tissue, cell type, or experimental condition. The plural metabolomes would refer to these metabolomic profiles across multiple samples, conditions, or species. As a linguistic variant, metabolomi is used by some authors to denote a collection or comparison of several metabolomes.

Relation to metabolomics: Metabolomics is the study of metabolomes—their composition, concentrations, and dynamics. Metabolomics uses technologies such as mass spectrometry, nuclear magnetic resonance spectroscopy, and chromatography to identify and quantify metabolites. Data are typically aligned to chemical identities and quantified across samples, enabling cross-sample comparisons of metabolomic profiles.

Applications and significance: Metabolomic comparisons across tissues, developmental stages, diseases, or environmental conditions can reveal biomarkers, pathways, and metabolic alterations. A multi-metabolome perspective can support cross-species studies, ecosystem analyses, or integrative omics research.

Limitations and usage notes: The term metabolomi is not widely adopted in English-language literature. When clarity is essential, it is advisable to use metabolomes and to define any non-standard plural early in the text to avoid confusion. See also metabolomics, metabolome.
