Copper Introduction Copper is a necessary trace element in human
body, copper is widely distributed in biological tissues, most of which
are organic complexes, many of them are metal proteins, which play a
functional role in the form of enzymes. Each enzyme containing a copper
protein has a clear physiological and biochemical effect, Many
oxygen-related electron transfer and redox reactions in biological
systems are catalyzed by copper-containing enzymes, which are vital to
the process of life.
The discovery of copper 1928-year Hart
reported that rats with anemia can only be corrected by supplementing
iron at the same time, it is believed that copper is a necessary element
of mammals. After the discovery of Menke ' s disease in 1962, it was
considered to be due to a disturbance of copper absorption after 10
years. 18th century copper has been proven to be a normal component of
blood, Its toxicity was described at the end of 19th century.
source copper is widely found in a variety of foods, oysters, shellfish
seafood food and nuts are good sources of copper followed by animal
livers, kidneys, cereal germ parts, legumes, and so on.
copper is absorbed in the metabolic absorbing diet, the blood is
transported to the liver through the portal vein, and the copper blue
protein is added, the blood is then released into the body, and most of
the endogenous copper is excreted into the gastrointestinal tract with
copper, which is not absorbed from the food, and a small amount of
copper is excreted through other channels. Copper is absorbed mainly in
the small intestine, small amounts are absorbed by the stomach.
