The study of substances of interest and species and their interactions, transformations, and functions in biological systems.

Focusing on the distributions and compositions of all metalloproteins in proteome, and the characterization of their structures and functions, may be regarded as the overlap of metallomics and proteomics.

Elementomics includes research in:

• Quantification of elements of interest in biological systems.
• The distributions of researched elements in biological systems.
• The specific element-assisted functions of biosciences in medicine, environment science, food science, agriculture, toxicology, biochemistry, etc.
