Zinc is vital for enzymes, cell division, and growth. Deficiency can cause stunting and impaired healing, especially in developing nations with poor diets.

Area of Science:

  • Biochemistry
  • Human Nutrition
  • Molecular Biology

Background:

  • Zinc is essential for over 200 enzymes, impacting genetic expression, cell division, and growth.
  • Zinc deficiency is linked to stunting, immune dysfunction, skin issues, and developmental problems.
  • Dietary factors and the body's anabolic state influence zinc deficiency risk.

Purpose of the Study:

  • To summarize the critical roles of zinc in human health.
  • To outline the consequences of zinc deficiency.
  • To discuss factors affecting zinc bioavailability and metabolism.

Main Methods:

  • Literature review of zinc's biochemical functions.
  • Analysis of deficiency symptoms and risk factors.
  • Examination of interactions between zinc, copper, and folate.

Main Results:

  • Zinc is crucial for numerous enzymatic activities and overall growth.
  • Deficiency manifests as impaired growth, immune response, and neurological function.
  • Bioavailability varies, with higher absorption from animal sources.
  • High doses of zinc or folate can disrupt other nutrient metabolisms.

Conclusions:

  • Zinc deficiency is a significant concern, particularly in developing countries.
  • Dietary choices and nutrient interactions (e.g., iron, folate) are key factors in zinc status.
  • Ensuring adequate zinc intake is critical for preventing deficiency-related health issues.
