Copper and zinc interact at the intestinal mucosal level, affecting copper absorption. Amino acids, such as histidine, may affect the absorption of these two elements by chelating these cations.
People also ask, what inhibits the absorption of copper?
Ascorbic acid is known to inhibit the absorption of copper.
Thereof, what inhibits absorption of zinc?
Cadmium, which is increasing in the environment, also inhibits zinc absorption. The amount of protein in a meal has a positive effect on zinc absorption, but individual proteins may act differently; e.g., casein has a modest inhibitory effect of zinc absorption compared with other protein sources.
High dietary zinc intakes depress copper absorption, in- crease copper sequestration in the mucosal cell bound to MT, and increase fecal excretion of copper. Conversely, increased copper absorption has been noted in zinc-deficient animals, and high dietary copper can depress zinc absorption.
