➤ It is present in the structures of the human body, such as the liver, kidneys, and endocrine glands.

➤ It is considered an essential component of several enzymes involved in the process of nitrogen fixation.

Plays an important role in the metabolism of purines and pyrimidines.

Promotes the cyclical functioning of biochemical processes in the structures of the human body (binds inorganic nitrogen).

➤ Presented as an activator of xanthine oxidase, nitrogenase, aldehyde oxidase, sulfite oxidase, and certain flavone group enzymes.

➤ Accelerates erythrocyte protein synthesis and has a regulatory effect on purine metabolism.

➤ The daily molybdenum concentration in the human body is 45 to 250 mg.

➤ Excess molybdenum causes disturbances in the metabolism of trace elements, the development of dermatological diseases, anemia, white blood cell deficiency, urolithiasis, and respiratory diseases.

➤ Endemic gout, musculoskeletal diseases (osteoarthritis), and hypotension are observed.

➤ Excessive amounts of Mo cause the excretion of copper elements from body structures such as the liver.

Provides phosphorus extraction from bone tissue.

➤ Aerosol mixture containing molybdenum damages the mucous membranes of the respiratory system (bronchi and lungs).

➤ Leads to gastrointestinal disorders.

➤ Accompanied by general weakness and exhaustion of body systems.

➤ Causes an increase in the rate of uric acid.

➤ Na₂MoO₄ (Sodium molybdate) - for the treatment of Mo deficiency - Tablet. 0.1 mg;

➤ (NH₄)₂MoO₄ (ammonium molybdate) - disinfectant effect.

 ➤ Ammonium molybdate is used to study the activity of endocrine organs.

-

➤ Causes gastrointestinal disorders.

➤ It affects certain trace elements, the epidermis of the skin and its mucous membrane

➤ Causes adverse effects on vital organs such as the liver and kidneys.

➤ Antidote: a solution of copper sulfate salt.

➤ Ammonium molybdate is a reagent for the qualitative determination of phosphorus and also has disinfectant properties.

➤ Molybdenum salts are used as colourants: sodium molybdate gives a blue colour, aluminium molybdate gives a blue colour.

➤ Mo has a very low coefficient of thermal expansion: when heated from 20 °C to 500 °C, the size increases by only 5.5*10^-6 of the initial value.

➤ Mo sublimates at high temperatures (transition from solid to gaseous state).

➤ A lot of Mo in legumes.
