Picture |the |beginning |synthesis |of |a |polymer |made |of |the |following |kind |of |monomers. |Each |
monomer |contains |2 |carbon |(C) |atoms, |6 |hydrogen |(H) |atoms, |and |1 |oxygen |(O) |atom; |each |
monomer |has |the |formula |C2H6O. |What |is |the |formula |of |the |molecule |formed |after |
connecting |three |of |these |monomers? |- |CORRECT |ANSWER✔✔-C2H6O |+C2H6O |+C2H6O |
=C6H18O3
|
C6H18O3-OH-OH
=C6H14O
Predict |whether |or |not |hydrogen |bonds |will |form |between |the |fatty |acid |tails |of |a |fat. |- |
CORRECT |ANSWER✔✔-1. |The |C-H |bonds |of |fatty |acids |are |non |polar
2. |The |C |atoms |in |C-C, |C=C, |and |C-H |bonds |of |fatty |acids |have |no |partial |electrical |charge.
3. |The |H |atoms |in |C-H |bonds |have |no |partial |electrical |charge.
, 4. |The |shared |electrons |are |loosely |held |in |the |C-H |bonds |of |fatty |acids.
Predict |whether |or |not |hydrogen |bonds |will |form |between |the |fatty |acid |tails |of |a |fat. |- |
CORRECT |ANSWER✔✔-Hydrogen |bonds |will |not |form
Is |Vitamin |D2 |Hydrophobic |or |hydrophilic |- |CORRECT |ANSWER✔✔-Hydrophobic |(Because |it |
has |more |non-polar |(C=O) |bonds |than |the |one |polar |(O-H) |bond)
Is |Vitamin |B5 |hydrophilic |or |hydrophobic |- |CORRECT |ANSWER✔✔-Hydrophilic
Which |lipid |has |the |highest |energy |content? |All |have |18 |carbon |atoms |in |each |of |their |fatty |
acid |chains. |
A) |a |fat |containing |only |saturated |fatty |acids
B) |a |phospholipid |containing |only |saturated |fatty |acids |- |CORRECT |ANSWER✔✔-A) |a |fat |
containing |only |saturated |fatty |acids
Which |lipid |has |the |lowest |number |of |C-H |bonds? |All |have |18 |carbon |atoms |in |each |of |their |
fatty |acid |chains. |
A) |a |fat |containing |only |monounsaturated |fatty |acids |
B) |a |fat |containing |only |saturated |fatty |acids |
