Lipids and Biomembranes

ID #1649

Glycerol in the phospholipid is part of the hydrophilic head. But on page 56 of Sadava, the picture says that Glycerol is part of the hydrophobic tail... Which is right?

The glycerol is definitely part of the hydrophilic part. The OH groups attached to glycerol are most definitely polar, and it's really just the fatty acid hydrophobic tails that constitute the hydrophobic portion.
