Zn is required for the structural integrity and binding to DNA in more than 2,000 transcription factors regulating the gene expression . It is important to mention that clinical manifestations resembling AE have been reported in several other nutritional deficiency states such as essential fatty acid, protein and amino acid deficiencies . Pilch SM, Senti FR (1985) Analysis of zinc data from the second National Health and Nutrition Examination Survey (NHANES II). In the early 1900s when advances in biochemistry appeared, many of the essential constituents of nutrition were introduced. It also has roles in pathogenesis of some dermatological disorders. In the structural role, Zn coordinates with certain protein domains, resulting in protein folding and producing structures such as "Zn fingers" [2,20]. CHAPTER 1. HHS About 80% of the plasma Zn is bound to albumin . Hall J1 (2005) Diagnostic dermatology. The homeostasis of Zn is highly regulated by the gastrointestinal tract. Nutritional Zn deficiency affects over 2 billion people in developing countries [2,3], whereas a considerable proportion of the western population is at risk of marginal Zn deficiency . Dermatitis herpetiformis is characterized by intensely itchy, chronic papulovesicular eruptions, usually distributed symmetrically on extensor surfaces (buttocks, back of neck, scalp, elbows, knees, back, hairline, groin, or face). Until the mid 20th century, the importance of Zn in the growth and development of mammals was not recognized. Total parenteral nutrition regimens usually include trace amounts of zinc. Elemental Zn is safe in the dose of 2.5 mg/kg/day (maximum 150mg/day) [28,58]. In the catalytic role, Zn is a critical component of hundreds of the metalloenzymes [2,8,20], such as alkaline phosphatase, carbonic anhydrase, pancreatic carboxypeptidases, RNA polymerases , alcohol dehydrogenase [2,9], DNA and RNA nucleotidyl transferases, glutamic, lactic and malic dehydrogenase and δ-aminolevulinic acid dehydratase .
