In human and animal tissues, copper is an important essential trace element. Copper can affect many biological pathways in human body. In healthy adults, the necessary copper concentration is 50-100 mg. Copper can be absorbed from the stomach and intestine through protein transporters. Then, copper associated with albumin and transcuprein is deposited in the liver. In blood, the major copper carrying protein is ceruloplasmin and the rest of copper is transported by albumin and histidine. If the balance of c...
