What is Avidin?

Avidin is a protein found in eggs of birds, amphibians and reptiles. It is produced in the eggs of these animals. Ovidukt is a route leading from the ovaries to the outside of the body in non-Saman vertebrates. Avidin is tetramic , which means it consists of four identical subunits . The most important effect of this protein is that it is very easy to bind to biotin vitamin. It is necessary for cell growth, production of fatty acids and metabolism of amino acids and fats. This vitamin also helps in the transmission of carbon dioxide and promotes hair and nail growth. Natural sources of this vitamin include bananas, salmon, liver and egg yolks. Bacteria present in the human intestinal tract also produce biotin.

with the abundance of sources of biotinity, in combination with the fact that the human body needs to work very little, the lack of this vitamin is rare. A high content of uncooked egg whites or other forms of raw eggs can lead to a lack of this vitamin. AvidinThe present in the eggs will bind to any biotin present in the body, which makes it unnecessary. When eggs are boiled, avidin is disabled inside the egg, but the biotin present in the yolk is not affected.

Biotin deficiency causes hair loss, scaly rash around the eyes and high cholesterol in the blood. It also causes neurological symptoms such as depression, hallucination and numbness in the hands and legs. A person who is missing in biotin is often said to have a with a biotin deficit characterized by an eye rash and odd distribution of fat in the face area.

There are also genetic disorders that cause increased need for biotin, and and and the procedures such as stomach removal, may have the same effect. Excessive alcohol consumption also leads to greater biotin need. Pregnancy is associated with a greater need for this vitamin, but only limited research has been carried out to determine the reason for this bikeeby.

Another form of avidin is streptavidin . It is produced by the streptomyces avidinii and has the same affinity to biotin as avidin. Streptavidin also has a tetmaic structure. This protein is used in laboratory applications such as cell and tissue dyeing, and is also used as a biotin detector.
