Document Summary

Involved in the functioning of over 300 different enzymes: e. g. superoxide dismutase. More zinc moves from the lumen into the mucosal cells. Little metallothionein is synthesized (b) high zinc intake: when zinc intake is high. Little zinc is transported from the lumen into the mucosal cells. More zinc moves out of the mucosal cells into the lumen & from the cytosol to the vesicles. Individuals most at risk: people with gastrointestinal diseases. Poor absorption: pregnant & breastfeeding women. Converts iron into a form that can bind to transferring for transport from body cells: coppers is also needed for: Depending on the soil they grow in: functions mostly through association with proteins called selenoproteins, several of these proteins, including glutathione peroxidise, are enzymes that help protect cells from oxidative damage, this spares vitamin e. Because this vitamin stops the action of free radicals once they are produced: is also needed for the synthesis of thyroid hormones.
