Consumption of raw eggs causes a biotin deficiency due to the binding of ____ to the biotin,thus preventing its absorption.

Question

Quizplus · Accepted Answer

Avidin is a protein present in raw egg whites that binds to biotin and forms an avidin-biotin complex that cannot be absorbed. This can lead to biotin deficiency if raw eggs are consumed in large amounts over a long period of time. Cooking the egg denatures avidin, which prevents it from binding to biotin, thus making it available for absorption. Heparin is an anticoagulant, carnitine is an amino acid derivative involved in fatty acid metabolism, and pyruvate is an intermediate in glucose metabolism; none of these substances bind to biotin.
