Aluminium, the third most common element in the Earth's crust (after oxygen and silicon), serves no function in living cells, but is toxic in large amounts, depending on its physical and chemical forms and magnitude, duration, frequency of exposure, and how it was absorbed by the human body. [38] Transferrins can bind aluminium. [39]
Common in medical implants. [11] The common compounds are nontoxic. [11] tungsten: 74: 4a: Is a (presumably essential) component of a few bacterial enzymes, and is the heaviest biologically essential element. [67] Appears to be essential in ATP metabolism of some thermophilic archaea. Can substitute for molybdenum in some proteins.

Graphic representation of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. CHNOPS and CHON are mnemonic acronyms for the most common elements in living organisms. . "CHON" stands for carbon, hydrogen, oxygen, and nitrogen, which together make up more than 95 percent of the mass of biological system
This is anything related to hormones, because these chemicals in their shape also look a little bit like hormones that we have in our body. They are related to things like thyroid dysfunction.
This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.
