avidin
/ˈævɪdɪn/
noun
- A protein found in raw egg whites that binds to biotin (a B vitamin) and can prevent its absorption in the body.
- Cooking eggs destroys avidin, so the biotin in cooked eggs is easily absorbed by your body.
- Scientists study avidin for its strong binding properties, which are useful in medical research.
- Eating large amounts of raw egg whites can lead to a biotin deficiency because avidin binds to the vitamin.
