Molybdenum: a trace element closely related to life

Molybdenum, like other elements such as copper, iron and zinc, is a trace element closely related to life. Molybdenum exists in human body, animals and plants. So, do you know the relationship between molybdenum and human health, molybdenum and animal health, molybdenum and plant health?

Molybdenum and human health

It is found that molybdenum already exists in the early stage of the development of life on earth. The human body generally contains 9 mg of molybdenum, most of which are stored in the blood, liver and heart.

As an essential trace element of human body, the content of molybdenum in the body will directly affect human health.

Appropriate amount of molybdenum is of great significance to human life activities. Because the metabolism of human body is carried out under the action of enzyme, and molybdenum is an important component of many kinds of enzyme in human body, which has many physiological functions such as anti-cancer, protecting cardiovascular system, carrying on the transmission of electron in cell, preventing caries and kidney stone.

However, molybdenum deficiency and excess can cause various diseases. For example, lack of molybdenum in human body can cause esophageal cancer, cardiovascular disease, kidney stone and other diseases; excessive molybdenum in human body can also damage reproductive cells and sexual functions, affecting human growth and development.

Some enzymes in human body that need molybdenum to play a role

1. Xanthine oxidase - regulates the production of uric acid in human body. If the molybdenum content in the diet is low, the lack or absence of xanthine oxidase can lead to kidney stones, even renal failure.

2. Aldehyde oxidase - involved in many important biochemical processes in human body. At present, the full function of this enzyme has not been fully understood, but it is considered necessary for healthy lung and blood circulation, production of steroids and processing of vitamin A.

3. Sulfite oxidase - to remove sulfite (a neurotoxin) from human body. In the human body, without this enzyme, there may be some nervous system diseases (some rare genetic diseases).

Sources of molybdenum in human body

The intake of molybdenum is related to the daily diet of human body. Molybdenum is mainly found in the liver organs of animals, such as the heart, liver, kidney, brain and pancreas of cattle and sheep. In plant food, wheat, barley, rye, millet in coarse grains, soybeans, mung beans, lentils in beans, spinach, lettuce, mustard, broccoli, kale and other vegetables with large leaves have rich molybdenum content (still need to be determined by the soil conditions of these plants). For adults, the recommended daily intake of molybdenum is 60 μ g, and the maximum tolerable intake is 350 μ g / day.

Molybdenum and animal health

The role of molybdenum in animals is mainly to help animals to remove waste from food digestion and promote energy production of cells. Molybdenum also affects the synthesis of animal proteins and the metabolism of phosphorus, sulfur, potassium, iron, copper, zinc and iodine. Because of the different digestive mechanism, some animals may easily accumulate molybdenum. In areas rich in molybdenum, ruminants such as cattle and sheep have a copper deficiency that can be corrected by adding copper to their feed.

Molybdenum and plant health

Molybdenum is an indispensable and substitute microelement for plant growth, and it is also an essential element for plant to utilize nitrate nitrogen. Molybdenum can promote the nitrogen fixation of legumes. If the legume is lack of molybdenum, the root system is reduced and the nodule is underdeveloped. Molybdenum can promote the absorption of phosphorus nutrients, promote the formation and transformation of carbohydrates in plants, improve the content of chlorophyll, and maintain the stability of chlorophyll. The lack of molybdenum in Australian farmland has reportedly reduced grain production by as much as 30%. A study in Egypt showed that adding molybdenum to orange trees increased fruit yield by 37%. The molybdenum added here is molybdenum fertilizer, including ammonium molybdate and sodium molybdate, etc.
