Avidin

Avidin is a glycoprotein found in the egg whites of some birds and reptiles. It has the property of forming a biologically inactive complex with biotin. With an increased intake of avidin from food, a person may develop biotin deficiency, which can lead to various diseases.

Avidin was discovered in the 1930s and was named after its discoverer, Austrian biochemist and immunologist Karl Landsteiner. Avidin has the unique ability to bind biotin, which is an important vitamin for the growth and development of the body. However, if there is an excess of avidin in food, biotin cannot be fully used by the body, which can lead to its deficiency.

Biotin deficiency can manifest itself in various forms, including dermatitis, alopecia, depression and other mental disorders. It can also affect the functioning of the immune system and lead to decreased immunity.

To prevent biotin deficiency, it is necessary to monitor the amount of avidin coming from food. For example, consumption of poultry eggs containing avidin should be limited or completely eliminated. It is also necessary to ensure a balanced diet and consume sufficient amounts of biotin in the form of supplements or foods containing it.

Thus, avidin plays an important role in the human body by binding biotin and making it available for use. However, with increased consumption of avidin, biotin deficiency may occur, which can negatively affect health. Therefore, it is necessary to monitor your diet and not overuse products containing avidin.

Avidin is a unique glycoprotein of animal origin, having a protein nature. By binding to boittin in intestinal cells, it significantly slows down the absorption of biotin into the lumen of the gastrointestinal tract. It is excreted through the kidneys, does not penetrate the placental barrier and is not metabolized. It accumulates in the body for quite a long time, which can lead to a decrease or disruption of the absorption of vitamin B7. Since 2015, a case of his overdose has been officially recorded. It has been established that pathological abnormalities can occur in elderly people with protein deficiency
