    Abstract. The absorption of zinc can be assumed to be determined to a large extent by the chemical environment at its site of absorption. Thus absorptive efficiency will be influenced by the solubility of the zinc compounds present by the presence of ligands of low molecular weight and by the competition between zinc and other minerals for carriers or uptake sites.
