droplets, and the electrically charged heads
project from the droplets and shield the
droplets from each other. The emulsion of fat
droplets is now stable.
These “surface-active” molecules have
many other applications as well. For example,
monoglycerides have been used for decades in
the baking business because they help retard
staling, apparently by complexing with
amylose and blocking starch retrogradation.
Carbohydrates
The name for this large group of molecules
comes from the early idea that they were
made up of carbon and water. They are indeed
made up of carbon, hydrogen, and oxygen
atoms, though the oxygen and hydrogen are
not found as intact water complexes within
the molecules. Carbohydrates are produced by
all plants and animals for the purpose of
storing chemical energy, and by plants to
