Vitamin E protects cell membranes by donating electrons, thereby stabilizing free radicals that damage the fatty acids in phospholipid bilayers.

Question

Quizplus · Accepted Answer

Vitamin E is a potent antioxidant that donates electrons to free radicals, thereby neutralizing them and preventing them from damaging cell membranes. The fatty acids in phospholipid bilayers are particularly susceptible to free radical damage due to their high degree of unsaturation, and vitamin E helps to protect these fatty acids by stabilizing free radicals and reducing the risk of lipid peroxidation.
