Ovomucoid is a protein found in the egg whites of birds, particularly in chicken eggs. It is a type of glycoprotein, meaning it has sugar molecules attached to it. Ovomucoid plays a crucial role in protecting the developing embryo by providing a barrier against pathogens and helping to maintain moisture. In addition to its protective functions, ovomucoid is also known for its allergenic properties. It is one of the main allergens in egg whites, which can trigger allergic reactions in some individuals. Understanding ovomucoid is important for both food safety and allergy management.
