    Study Notes

    Essential Trace Minerals and Their Disorders

    • Severe zinc deficiency is caused by mutation of the ZIP4 gene and is an autosomal recessive inborn error.
    • Excessive zinc exposure can lead to gastrointestinal symptoms, heme synthesis decrease, and hyperglycemia.
    • Excessive zinc exposure can cause abdominal pain, diarrhea, nausea, vomiting, and altered immune function.
    • Excessive zinc exposure can lead to copper deficiency, anemia, neutropenia, and hyperglycemia in chronic conditions.
    • Increased intracellular zinc levels may result in cellular toxicity, ischemia-reperfusion injury, and Alzheimer’s disease.
    • Copper is essential for various biological functions and is mainly absorbed in the small intestine.
    • Ceruloplasmin, an acute phase reactant, plays a crucial role in iron oxidation and has antioxidant properties.
    • Disorders of copper metabolism include Menkes’ disease and Wilson’s disease, each with distinct symptoms and genetic causes.
    • Wilson’s disease is characterized by copper accumulation in tissues, leading to neurological disorders and liver cirrhosis.
    • Copper toxicity can result from exposure to copper pots, burn pomades, and fungicides, causing various health issues.
    • Manganese is important for bone development, wound healing, and several enzymatic processes.
    • Chromium exists in different valence forms and is crucial for glucose regulation, insulin effectiveness, and atherosclerosis prevention.
