Zinc (Zincum, Zn) is a chemical element of Group II of the Periodic Table proposed by Mendeleyev. Zinc is classified as a microelement necessary for normal human life; it is part of the carbonic anhydrase, which is an enzyme involved in maintaining acid-base balance, and other metal enzymes.

In the human body, an average of 2-3 grams of gold seal zinc oxide (i.e. about the same as iron, and 10-25 times more than copper) is found. The highest concentration of gold seal zinc oxide is observed in the prostate gland (approximately 15 mm). The concentration of Zn2 + ions in the tissues averages 0.3-0.5 mm.

Zinc affects the activity of the triple hormones of the pituitary gland; gold seal zinc oxide  participates in the realization of the biological action of insulin; it has lipotropic properties normalizing fat metabolism and increasing the intensity of the decomposition of fats in the body. Bp zinc oxide also prevents fatty dystrophy of the liver. There are data on the participation of zinc in hematopoiesis; Zinc is necessary for the normal functioning of the pituitary gland, pancreas, seminal vesicles and prostate.

Companies like G.H. Chemicals Ltd. which produce bp zinc oxide supply its compounds also for medical industry to make drugs. Lack or excess in the body of zinc causes a violation of the synthesis and the properties of the corresponding metalloproteins, as well as other organometallic compounds necessary for the body. Many zinc compounds are used as insecticides, fungicides, preservatives for wood, additives for lubricating oils, constituents of a range of dyes, phosphors, etc. Zinc is a component of brass, nickel silver, tombac and other alloys, used for anticorrosion coating of galvanized steel and cast iron. In industries associated with the production and use of zinc and its compounds, it may represent occupational hazards.

Radioactive zinc is used in various fields of science and technology as an isotope indicator, as well as in biological studies, for example, in the study of zinc metabolism in the body and elucidating the role of this important trace element in the vital activity of animals and plants. Compounds labeled with radioactive zinc represent different zinc salts mainly zinc chloride.

The human need for zinc

In the case of proper nutrition, hypocinosis in a person develops extremely rarely unless the food balance or the absorption and of zinc are violated. Diets with a very high content of cereals can cause zinc deficiency in humans, since they are rich in phytic acid, which prevents the absorption of zinc salts from the intestine into the blood. Zinc deficiency manifests itself in the deceleration of growth and underdevelopment of the reproductive organs in adolescence.

Milk contains only a little of zinc and therefore, it is recommended for infants to consume vegetable and fruit juices, which are sources of not only vitamins and copper, but also zinc.

The need for zinc (mg per day):

  • In adults – 10-15;
  • In pregnant women – 20;
  • In brestfeeding mothers – 25;
  • In children – 4-5;
  • In infants – 0.3
