What are micelles and where are they used in?
Spherically shaped grouping of phospholipids found in liquid.
They are used in detergents and soaps
200
What are glycolipids?
Lipids attached to an oligosaccharide
200
What do triglycerides consist of?
A glycerol head and 3 fatty acids
300
What is the functional group for lipids?
Carboxyl
300
Are unsaturated or saturated fats found in animals?
Saturated
300
What is a thin membrane that is made up of two layers of lipid molecules?
A phospholipid bilayer
300
What do lipoproteins do?
Carry cholesterol and triglycerides throughout the body
300
Draw the carboxyl functional group
400
What are the different types of lipids?
Fats/oils, phospholipids, glycolipids, steroids, and lipoproteins
400
What is the difference cis and trans unsaturated fatty acid?
Cis= hydrogens are on the same side
Trans= bad, hydrogens are on the opposite side
400
Draw a micelle and label the polar and nonpolar parts
Outside is polar
Inside is nonpolar
400
What is the difference between HDL and LDL in cholesterol?
HDL:
Good cholesterol
More protein than cholesterol
LDL:
Bad cholesterol
More cholesterol than proten
400
How do you name an Omega Fatty Acid?
Count the number of carbons until we reach the C=C bond. (Count on the opposite side of where the carboxyl is located)
500
What are the functions of lipids?
Energy storage
cell membrane
signaling
protection, insulation, padding
500
What is the difference between saturated and unsaturated fats?
Saturated:
- maximum number of hydrogens
- solid at room temperature
-straight chain
Unsaturated:
- one or more C=C double bonds
- liquid at room temperature
- bent

Draw a liposome. What are they used for?
They are used to carry/administer drugs into the tissue.
500
What does the surface of a lipoprotein contain? What does the interior contain?
The surface contains proteins and phospholipids while the interior contains cholesterol and triglycerides.
500
When two fatty acids join together, what is the bond called?
Ester linkage
