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.

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

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

What’s What? • Identify the glycerol molecule • The fatty acids

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

Fats are used as an insulator • Fats help keep animals warm

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.

Who’s got the power? • Sugar • Fatt

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 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

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