What makes the "head" of a phospholipid hydrophilic?

Question

Quizplus · Accepted Answer

The phosphate group in the head of a phospholipid carries a negative charge, which makes it polar and hydrophilic (water-loving). The fatty acid tails are nonpolar and hydrophobic (water-fearing), which allows for the formation of lipid bilayers in cellular membranes. Option A is incorrect because an even distribution of electrons across the fatty acids would not create a polar head. Option B is incorrect because an uneven distribution of electrons across the fatty acids would also not create a polar head. Option D is incorrect because a negative charge would make the head polar, not nonpolar.
