A significant number of chemical elements are either essential for life with known functions, or present in organisms with poorly defined functional outcomes. We do not know all the essential elements with certainty and we know even less about the functions of apparently non-essential elements. in this article, I discuss; a basic for a biological periodic system of the elements end that biochemistry should include the elements that are traditionally part of inorganic chemistry ant net only those that are in the purview of organic chemistry. A biological periodic system of the elements needs to specify what “essential” meant and to which biological species it refers. It represents a snapshot of our present knowledge and is expected to undergo further modifications in the future. Art integrated approach of biometal sciences called metallomics is required to understand rite interactions of metal ions, the biological functions that their chemical structures acquire it the; biological system, and how their usage is fine-tuned in biological species and in populations of species with genetic variations (the variome).
