An Analogy For Bio-diesel
a: Lipid ~
b: a three-legged octopus
What: "Basically, they're all lipids, and a lipid is like a three-legged octopus. So we take that lipid, that oil, we add a little alcohol in the catalyst, and we cut its head off. The head floats down to the bottom- that's the by-product, glycerol- and the legs, once they're tested and everything has happened properly- then that's bio-diesel."

The Fluid Mosaic Membrane Model
a: A lipid ~
b: the water of a lake for protein boats
What: "Lipids are like the water of a lake in which proteins "float." This general design is called the fluid mosaic model."

a: lipid bilayer ~
b: a sandwich
What:

a: lipid bilayer ~
b: soap bubble
What:
"Water forms hydrogen bonds with individual phospholipid molecule. As a result, individual lipid molecules are free to move about within the membrane, so the lipid bilayer is like the "shell" of a soap bubble."

a: lipid bilayer ~
b: oil
What:
"Because the lipid bilayer is like an oil, the cell utilizes all sorts of other proteins and macromolecules."

a: hydrophillic surface of a lipid bilayer ~
b: the surface of a pond
What:
The commonalities are the fluidity of the watery surfaces. If you put a small boat on the surface of pond, it will float and slowly move around. The media in which it is sitting is fluid. The frozen surface of a pond is solid. If a small boat were place on top it would just sit there, motionless.
