Respuesta :
Eating too many raw egg whites may adversely affect the absorption of biotin.
Answer:
a. biotin
Explanation:
Egg whites are a rich source of biotin (a vitamin)
Raw egg whites contain a protein avidin which can bind biotin and stops/inhibits its absorption from gut.
However, if we cook the egg white, avidin is denatured (looses its three dimentional structure) and does not bind biotin anymore.
