The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa 3), the fourth complex of the electron transport chain found in the inner membrane of the mitochondria of eukaryotic cells. It attaches to the iron within this protein. The binding of cyanide to this enzyme prevents transport of electrons from cytochrome c to

The term "cyanide" refers to any chemical containing a carbon-nitrogen (CN) bond. Many substances contain cyanide, but not all of them are deadly poisons. Sodium cyanide (NaCN), potassium cyanide (KCN), hydrogen cyanide (HCN), and cyanogen chloride (CNCl) are lethal, but thousands of compounds called nitriles contain the cyanide group yet aren't as...
In a nutshell, cyanide prevents cells from using oxygento make energy molecules. The cyanide ion, CN-, binds to the iron atom in cytochrome C oxidase in the mitochondria of cells. It acts as an irreversible enzyme inhibitor, preventing cytochrome C oxidase from doing its job, which is to transport electrons to oxygen in the electron transport chain...
Cyanide can be used as a poisonor chemical warfare agent, but most people are exposed to it unintentionally. Some ways to be exposed to cyanide include: 1. Eating cassava, lima beans, yucca, bamboo shoots, sorghum, or almonds 2. Eating apple seeds, cherry stones, apricot pits, or peach pits 3. Smoking cigarettes 4. Burning plastic 5. Burning coal 6...
Inhaling a high dose of cyanide gas rapidly causes unconsciousness and often death. Lower doses may be survivable, especially if immediate aid is provided. The symptoms of cyanide poisoning are similar to those displayed by other conditions or exposure to any of a number of chemicals, so don't assume cyanide is the cause. In any event, do remove ...
How much cyanide is too much depends on the route of exposure, the dose, and the duration of exposure. Inhaled cyanide presents a greater risk than ingested cyanide. Skin contact is not as much of a concern (unless the cyanide has been mixed with DMSO), except touching the compound could lead to accidentally swallowing some of it.As a rough estimat...
Because it's a relatively common toxin in the environment, the body can detoxify a small amount of cyanide. For example, you can eat the seeds of an apple or withstand cyanide from cigarette smoke without dying. When cyanide is used as a poison or a chemical weapon, treatment depends on the dose. A high dose of inhaled cyanide is lethal too quickly...

- Not everyone is able to smell cyanide. Approximately 60% of people can detect the bitter, almond odor of cyanide.
First isolated in 1782, cyanide is a compound composed of carbon atom triple-bonded to a nitrogen atom (C≡N). Cyanide is a naturally occurring chemical can be produced by certain types of bacteria, fungi, and algae and found in several types of plants, seeds, and fruit stones, including bamboo, cassava, bitter almonds, apples, and peaches.
Furthermore, cyanide was found to attach more readily to plasma albumin than to hemoglobin (McMillan and Svoboda 1982). It was suggested that hemoglobin in erythrocytes binds cyanide molecules, but does not play any role in their metabolism. Some authors argue that cyanide in red blood cells may be biologically active . In addition, it is known ...

Quick Facts. Mechanism: Cyanide prevents cells from using oxygen, necessary for our cells to live. Cells take in cyanide as it distributes throughout the body. Entering the cells' mitochondria (energy producers), cyanide displaces oxygen bonded to proteins. Those proteins, cytochrome, cannot perform its normal function of producing energy using ...
