Bio chemical assessment of zinc

Zinc

Zinc is the second most abundant trace micronutrient in body after iron. Although required in trace amount, zinc catalysis more than 100 reactions within the body . The main functions of zinc include enzyme activation, proteins, synthesis and regulations of gene expression. Zinc is absorbed from small intestine and prolonged low dietary intake result in zinc deficiency. Zinc deficiency is classified as an 11th major risk factor in global disease burden and can result in short stature, reduced sensitivity of taste buds, and impaired functionality of reproductive organs. Since the human body does not store zinc, it must be consumed as a part of regular diet. Excessive intake (>10 times of RDA) decrease immunity and can induce copper deficiency .
