    Studysummary This article reviews the roles of zinc and copper in biological processes, especially their implications for metabolism and deficiency-related disorders, but it does not present new clinical results. Our plain-language summary of this paper — not a Tressless recommendation.
    The document discussed the roles of zinc and copper in human nutrition, highlighting their importance in various biological processes. Zinc was noted for its role in preventing malformations in offspring of zinc-depleted rats and its importance in taste and smell, though its role in wound healing in humans was less clear. Copper was recognized for its essential role in erythropoiesis alongside iron and its involvement in connective tissue and central nervous system disorders in animals. Copper deficiency in humans was considered unlikely until linked to specific syndromes in infants receiving total parenteral nutrition, with copper supplementation correcting some symptoms. The document also mentioned the discovery of zinc as a component of essential enzymes like carbonic anhydrase and carboxy peptidase A.
