ANSWERS
PART
ONE - SATURATED & UNSATURATED FATS
QUESTIONS
- How
many bonds does each carbon atom form? (four)
- How
many bonds does each hydrogen atom form? (one)
- How
does the structure of saturated fat differ from the unsaturated
fat? (saturated fat has only single bonds, unsaturated fat
includes double bonds)
- Why
do you think that the terms saturated and unsaturated are
applied to these molecular backbones? (In the saturated
molecule, all of the bonds are used up by attaching to different
atoms. The bonding opportunities are "saturated" with different
atoms. In the unsaturated version, the double bonds that
can be replaced by a single bond, thereby making available
more sites for new atoms. These multiple bonds are not fully
"saturated" with their potential for bonding)
