A cyanide is any chemical compound that contains the cyano group -CN, with the carbon atom triple-bonded to the nitrogen atom. The CN group can be found in many kinds of compounds. Some are gases, others are solids or liquids. Some are salt-like, some covalent. Some are molecular, some ionic, and many are polymeric. Those that can release the cyanide ion CNˆ' are highly toxic.

The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa3) in the fourth complex of the electron transport chain (found in the membrane of the mitochondria of eukaryotic cells). It attaches to the iron within this protein. The binding of cyanide to this cytochrome prevents transport of electrons from cytochrome c oxidase to oxygen. As a result, the electron transport chain is disrupted, meaning that the cell can no longer aerobically produce ATP for energy. Tissues that depend highly on aerobic respiration, such as the central nervous system and the heart, are particularly affected. This is an example of histotoxic hypoxia.
