Copper transport refers to the movement of copper ions within biological systems, essential for various cellular functions. In humans, copper is absorbed in the intestines and then transported through the bloodstream bound to proteins like ceruloplasmin. This process ensures that copper reaches organs and tissues where it is needed for processes such as energy production and iron metabolism. Cells also have specific mechanisms to regulate copper levels, preventing toxicity. Proteins like ATP7A and ATP7B play crucial roles in copper transport by facilitating its entry into cells and excretion from the liver. Proper copper transport is vital for maintaining overall health and preventing disorders related to copper imbalance.
