Phospholipid head polar
WebA phospholipid has a "head" made up of a glycerol molecule attached to a single ______, which is attached to another small molecule. Phosphate group Because the phosphate group and its attachments are either charge or polar, the phospholipid head is ______, which means it has an affinity for water. Hydrophilic WebA phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group. Biological membranes usually involve two layers of phospholipids with their tails pointing inward, an arrangement called a phospholipid bilayer.
