Question

what part of the phospholipid is hydrophobic?
a the fatty - acid tail
b the glycerol backbone
c the polar head group
d all of the phospholipid

Explanation:

Phospholipids have a structure with a polar, hydrophilic head group (containing phosphate) and non - polar, hydrophobic fatty - acid tails. The glycerol backbone is part of the structure but is not the main hydrophobic part. The polar head group is hydrophilic. Not all of the phospholipid is hydrophobic.

Answer:

A. the fatty - acid tail
