Metabolic interactions of copper with other trace elements.

C F Mills

    Ciba Foundation Symposium
    |January 1, 1980
    PubMed
    Summary

    Trace elements like zinc, cadmium, molybdenum, and iron interact with copper metabolism, affecting animal and human health. Understanding these interactions is crucial for managing copper deficiency and toxicity.

    Area of Science:

    • Biochemistry
    • Nutritional Science
    • Toxicology

    Background:

    • Metabolic interactions between copper and other trace elements significantly impact health.
    • These interactions influence susceptibility to copper deficiency or toxicity and their consequences.
    • Antagonistic trace elements can impair copper utilization through various mechanisms.

    Purpose of the Study:

    • To review recent studies on the mechanisms of interactions between copper and other trace elements.
    • To elucidate how zinc, cadmium, molybdenum, and iron affect copper metabolism.
    • To understand the biochemical and pathological implications of these metabolic interactions.

    Main Methods:

    • Literature review of recent studies.
    • Analysis of biochemical pathways involved in trace element metabolism.
    • Examination of mechanisms affecting copper absorption, transport, and distribution.

    Main Results:

    • Antagonistic trace elements reduce copper solubility, compete for absorption/transport, or alter tissue distribution.
    • Copper deficiency disrupts iron-dependent functions by affecting iron flux between plasma and cells.
    • Specific interactions between copper and zinc, cadmium, molybdenum, and iron were investigated.

    Conclusions:

    • Interactions between copper and other trace elements are complex and multifaceted.
    • These interactions have significant implications for nutritional status and health outcomes.
    • Further research into these mechanisms is essential for preventing and treating trace element imbalances.
