Question

Is nickel in your body? Does your body need it? And how does it affect you body? You dont have to answer all of them

Answer 1

Nickel is usually found in trace amounts in the body. Humans may be exposed to nickel by breathing air, drinking water, eating food which contains nickel or smoking cigarettes. It is not needed by the body and too much of it can be extremely harmful.

An uptake of too large quantities of nickel has the following consequences:
- Higher chances of development of lung cancer, nose cancer, larynx cancer and prostate cancer
- Sickness and dizziness after exposure to nickel gas
- Lung embolism
- Respiratory failure
- Birth defects
- Asthma and chronic bronchitis
- Allergic reactions such as skin rashes, mainly from jewellery
- Heart disorders

Answer 2

Hi. From the web : "Many but not all hydrogenases contain nickel in addition to iron-sulfur clusters. Nickel centres are a common element in those hydrogenases whose function is to oxidise rather than evolve hydrogen. The nickel centre appears to undergo changes in oxidation state, and evidence has been presented that the nickel centre might be the active site of these enzymes.

A nickel-tetrapyrrole coenzyme, Co-F430, is present in the methyl CoM reductase and in methanogenic bacteria. The tetrapyrrole is intermediate in structure between porphyrin and corrin. Changes in redox state, as well as changes in nickel coordination, have recently been observed."
