Lipids Flashcards
1
Q
Fat molecules two main components
A
Glycerol
Fatty acids
2
Q
Glycerol
A
organic compound with three carbons, five hydrogens and three hydroxyl (OH) groups
3
Q
Fatty acids
A
have a long chain of hydrocarbons to which a carboxyl group is attached (COOH)
4
Q
Ester bond
A
fatty acids attach to each of the glycerol molecule’s three carbons with an ester bond
5
Q
Saturated
A
only single bonds between carbons
- pack tightly and are solid at room temp
6
Q
Unsaturated
A
Hydrocarbon chain contains double bonds
- most are liquid at room temp
- cis = hydrogens on same side (kink)
- trans = hydrogen atoms on different sides
7
Q
Monounsaturated
A
one double bond
8
Q
Polyunsaturated
A
two or more double bonds
9
Q
Alpha naming system
A
count carbons from the carboxylic acid end
10
Q
Omega naming system
A
double bond distance from the methyl end
