FATTY ACIDS Flashcards
1
Q
WHAT IS THE STRUCTURE OF FATTY ACIDS?
A
- LONG HYDROCARBON CHAINS
- A CARBOXYL GROUP
2
Q
WHAT VARIES BETWEEN DIFFERENT FATTY ACIDS?
A
THE LENGTH OF THE HYDROCARBON CHAIN
3
Q
WHAT IS THE HYDROCARBON CHAIN?
A
NON-POLAR (E.G. NOT ATTRACTED TO WATER)
4
Q
WHAT MOLECULES CAN’T DIFFUSE BETWEEN FATTY ACIDS?
A
WATER-SOLUBLE / POLAR MOLECULES
5
Q
DESCRIBE SATURATED FATTY ACIDS
A
- SINGLE CARBON-CARBON BONDS
- CONTAIN THE MAXIMUM NUMBER OF HYDROGEN ATOMS
- STRAIGHT CHAINED
- TIGHTLY PACKED WITH STRONGER INTERMOLECULAR FORCES
- SOLIDS AT ROOM TEMPERATURE
6
Q
DESCRIBE UNSATURATED FATTY ACIDS
A
- SOME CARBON-CARBON SINGLE BONDS
- SOME CARBON-CARBON DOUBLE BONDS
- DON’T CONTAIN THE MAXIMUM NUMBER OF HYDROGEN ATOMS
- CHAINS HAVE KINKS
- NOT TIGHTLY PACKED WITH WEAKER INTERMOLECULAR FORCES
- LIGUID AT ROOM TEMPERATURE
7
Q
WHAT IS MONOUNSATURATED?
A
ONE CARBON-CARBON DOUBLE BOND
8
Q
WHAT IS POLYUNSATURATED?
A
TWO OR MORE CARBON-CARBON DOUBLE BONDS
9
Q
WHAT ARE FATTY ACIDS KNOWN FOR BEING?
A
HYDROPHOBIC (REPELS WATER)
