combined with 3 FA for triglyceride or 2 for di or 1 for mono.
Has an ester bond to link FA and glycerol to from triglyceride

What is the structure of a phosphoglyceride?
-lipophilic and hydrophilic ends
similar to triglycerides but have 2 FA instead of 3

What is the structure for fatty acids?
Chains of carbon and hydrogen atoms with a terminal carboxyl group.
Straight chains and are either saturated or non saturated
9 of 18
What is the structure for a saturated fatty acid?
No double carbon carbon bonds
-Anoic= saturated
10 of 18
What is the structure for an unsaturated fatty acid?
has one or more double bonds.
Bonds usually methylene interrupted
Enoic=unsaturated (oleic acid)

What are the 4 abbreviation systems for fatty acids?
-Trivial names
-IUPAC names
-The carboxyl reference system
-Omega labelling system
12 of 18
How is the omega system used?
So the first number represents how many carbons are used in it. The next is how many double bonds there are and the next number represents what carbon number the double bond is on.
13 of 18
How is the carboxyl reference system used?
The first number represents how many carbons are in the chain and the second number is how many double bonds
14 of 18
How can you tell if there are any double bonds or not in a carbon?
If the name has anoic in it, it means there are no double bonds, if the name has enoic in it, it means there are some double bonds.

What type of fatty acid wouldn't have a kink in it?
Trans fatty acid
17 of 18
