Zinc is termed as an essential element required for supporting the activities of the life.
Zinc is estimated to have 3,000 of the hundreds of thousands of proteins in the human body and these contain zinc
prosthetic groups called the zinc finger. There are dozen numbers of available types of cells in the body of the
human and it helps in the secretion of zinc ions and the role of these secreted zinc ion helps in studying detailed
about the medicine and health care of the human. The zinc ions are also considered as the neurotransmitters. Cells
like salivary gland, immune system and prostrate helps in the signaling of the zinc ions.
Zinc is involved in the process of olfaction and the olfactory receptor consists of zinc binding sites and the
deficiency in the zinc results in the anosmia. Zinc is a motivator of certain types of enzymes and this helps in
the carbonic anhydrase. Carbonic anhydrase is considered as the important factor for transportation of the carbon
dioxide in the vertebrate blood. This is also essential for the leaf formation in the plants, the production of
indole acetic acid called auxin and anaerobic respiration known as alcoholic fermentation.
The existence of zinc is present in oysters, lesser degree in animal proteins, almonds, beans, nuts, whole
grains, sunflower seeds and pumpkin seeds. The neck of the turkey and the chuck of the beef contain good sources of
zinc. Phytates normally reduces the iron content in the body. Good sources of zinc are present in whole grain
breads, cereals, legumes and other products.
Researches have proved that zinc combined with the antioxidants help in the delay process of age-related macular
degeneration. Consumption of significant amount of zinc also helps in the impede onset of flu. According to the US
recommended dietary allowance for zinc is 11 mg for males and 8mg for females and higher amounts of zinc is
recommended during the period of pregnancy and lactation.
The deficiency in zinc results in the inadequate dietary intake of zinc and promotes to various diseases with
zinc losses and result in the physiological state of increased zinc. Individuals consuming low quantity of zinc
results in the zinc deficiencies. Intestinal malabsorption relates to the disease containing zinc losses.
Developing countries face the problem of fecal losses caused due to diarrhea due to the loss in zinc. Intestinal
tract changes resulting in absorbability and permeability affects the viral, protozoal and bacteria pathogens and
promotes in the fecal loss of zinc. Increased amount of zinc is essential in the growth of infants, children and
mother during pregnancy.
Some of deficiencies in zinc are skin lesions, hair loss, diarrhea, eyesight loss, taste, smell, memory loss and
wasting of body tissues. The deficiency in zinc results in the malfunctions of the organs and functions of the
human body. Acrodermatitis enteropathica is caused due to the congenital abnormalities due to the deficiency in
zinc. Results have proved that the world is facing 25% of risk in the world population towards zinc deficiency.
Zinc deficiency during pregnancy affects the mother and the baby. Researches have proved that out of seven
pregnancies there arises one abortion and two malfunctions due to the severe deficiency in the zinc. A review on
zinc substitution trials during pregnancy has not reported significant effect on the neonatal survival.
