Introduction: Copper is an essential trace mineral required by the body for several important functions, including energy production, connective tissue formation, and the regulation of red blood cell formation. Copper is found in a variety of foods, and deficiencies are rare in healthy individuals. However, copper supplementation may be necessary in individuals with certain medical conditions or dietary restrictions. This report will examine the importance of copper in human health and provide examples of its roles in different physiological processes. Copper in Energy Production: Copper is a crucial component of many enzymes involved in the production of energy within the body. The mineral is required for the function of cytochrome c oxidase, an enzyme that helps produce ATP (adenosine triphosphate), the main energy currency of the body. Without adequate copper levels, ATP production is reduced, leading to fatigue and weakness. Copper in...
