Cell Membranes: Lipids (Ch 10) Fluid mosaic model of biomembrane
lipid bilayer (5 nm) with proteins
Fluid--sea of lipids
Mosaic--proteins floating around
Biomembrane is composed of lipids, proteins, and carbohydrates Exoplasmic (extracellular) face
Cytosolic face http://multimedia.mcb.harvard.edu/anim_innerlife.html
Lipids Lipids are amphipathic
A lipid has a hydrophilic polar head and 2 hydrophobic tails.
It is amphipathic, meaning that it has dual solubility
Heads like water and Tails don’t.
Usually, one tail has 1-3 cis-double bond (s) (unsaturated)
2 hydrophobic tails
Biomembranes Biomembranes of a typical cell contains 500-1000 different lipid species.
