fatty acid
A fatty acid is nothing more than a long C-H chain with a carboxyl group (COOH) on the end.

The COOH gives it an acid property.

The 3….dots represent the chain is very long.

Fatty Acid
glycerol
Glycerol Always looks the same

3 C’s with 3 OH’s and everything else H’s.

Glycerol
energy
Energy
  • Fats have a lot of energy stored up in their bonds.
  • That’s why the human body stores fats as an energy source.
  • When your body needs extra fuel, your body breaks down the fat and uses it as energy.
  • Sugar give you only a little bit of energy
  • Fat molecules give off much more energy.
saturated and unsaturated fats
Saturated and Unsaturated fats
  • There are two kinds of fats saturated and unsaturated
  • Unsaturated fats have at least one double bond (C=C) in one of the fatty acids
  • Saturated fats have no double bonds. (C-C)
steroids
Steroids
  • Steroids are lipids
  • Since they are lipids they can cross the cell membrane
  • Are hormones
  • Have a 4 ring structure
steroid abuse
Many body builders and athletes use steroids.

They are destroying their internal organs

Cause liver and kidney damage

Steroid Abuse
waxes
Waxes
  • Waxes are used to coat and protect things in nature.
  • Your ears make wax
  • Plant leaves make waxes to stop evaporation.
is this dehydration synthesis or hydrolysis
Is this dehydration synthesis or Hydrolysis?
  • Lipid + water  3 fatty acids + glycerol
