Define about the Storage of Zinc in Humans?
Zinc is found in most organs, concentration being higher in liver, kidney, muscle, skin and bone. Zinc content of muscle, brain, lung and heart is relatively stable and does not respond to changes in dietary zinc intake. Similarly, release of zinc from bones is very slow and does not contribute zinc to other tissues during deprivation. When dietary zinc intake is insufficient, liver metallothionein zinc appears to be mobilized and redistributed. As dietary zinc intake decreases, liver and RBC metallothionein bound zinc reduces. Zinc which is not absorbed by our gastrointestinal tract tends to get excreted by our body. Zinc may also get lost from our body due to damage to cells/tissues of our body or as a result of normal physiologic processes.
