,Concept 7.1: Cellular membranes are fluid
mosaics of lipids and proteins
• Phospholipids are the most abundant lipid in the plasma
membrane
• Phospholipids are amphipathic molecules, containing
hydrophobic and hydrophilic regions
• Amphipathic phospholipids leads to a bilayer structure.
Explain.
,Review Ch. 5: Phospholipids (1 of 2)
• In phospholipids, two
fatty acids and a
phosphate group are
attached to glycerol
– The two fatty acid
tails are hydrophobic
– The phosphate head
group is hydrophilic
Figure 5.11a and b
, Cellular Membranes
A phospholipid bilayer can
exist as a stable boundary
between two aqueous
compartments
• hydrophobic (nonpolar)
tails come together to
exclude water
• hydrophilic heads face the
aqueous cytoplasm and
extracellular
environments
