<b>Phospholipids, made from two fatty acids and a polar head region,
form important double layers (bilayers) in water.</b> In cells, the
double layers create flexible walls that separate spaces from one
another. Examples of spaces that membranes separate are: inside and

nucleus, chloroplasts and mitochondria.
