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 Always looks the same 3 C’s with 3 OH’s and everything else H’s. Glycerol.

Presentation Transcript

  1. 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

  2. Glycerol Always looks the same 3 C’s with 3 OH’s and everything else H’s. Glycerol

  3. To build one lipid molecule, we combine 3 Fatty acids with 1 glycerol by the process of ?

  4. Identify the glycerol molecule The fatty acids What’s What?

  5. Remember fats have a hydrophilic head and a hydrophobic tail. Fats make up most of the cell membrane

  6. Fats help keep animals warm Fats are used as an insulator

  7. 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.

  8. Sugar Fatt Who’s got the power?

  9. 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)

  10. Steroids • Steroids are lipids • Since they are lipids they can cross the cell membrane • Are hormones • Have a 4 ring structure

  11. Many body builders and athletes use steroids. They are destroying their internal organs Cause liver and kidney damage Steroid Abuse

  12. Waxes • Waxes are used to coat and protect things in nature. • Your ears make wax • Plant leaves make waxes to stop evaporation.

  13. Is this dehydration synthesis or Hydrolysis? • Lipid + water  3 fatty acids + glycerol

  14. Don’t forget to finish your lab! The Mad Scientist
