Draw a simplified diagram Head = phosphate and glycerol
of the structure of the Tails = fatty acids
phospholipid, including a
phosphate-glycerol head
and two fatty acid tails.

, Understanding:
Phospholipids form
bilayers in water due to
the amphipathic
properties of
phospholipid molecules.
Define hydrophilic. Polar and/or charged molecules (or
regions of molecules) to which water can
attract.
Understanding:
Phospholipids form "Water loving."

bilayers in water due to
the amphipathic
properties of
phospholipid molecules.
Define hydrophobic. Nonpolar molecules (or regions of
molecules) to which water will not
attract.
Understanding:
Phospholipids form "Water fearing."

bilayers in water due to
the amphipathic
properties of
phospholipid molecules.
Define amphipathic. A molecule that contains both hydrophilic
and hydrophobic regions.

Understanding: i.e. a phospholipid

Phospholipids form
