Fats, oils, wax, and steroids
3
Q
properties of a lipid:
A
greasy, not soluble in water, nonpolar molecules, and hydrophobic
4
Q
chemical formula:
A
contain only carbon, hydrogen, and a few oxygen molecules
5
Q
lipid monomer
A
3 fatty acid chains and a glycerol molecule
6
Q
3 different types of fatty acid chains:
A
- saturated fats
- unsaturated fats
- transfats
7
Q
Saturated Fats: (bad)
A
- made from saturated fatty acids which have no C-C double bonds
- They are solid at room temp
- have a straight fatty acid chain
- they can make you sick by clogging your arteries
8
Q
Unsaturated Fats: (good)
A
- made from unsaturated fatty acids and have one or more C-C double bonds
- they are liquids at room temp
- have a bent fatty acid chain which keeps the molecules from packing together
