Model Set I
 
Ia. Draw a Fischer projection formula or Haworth formula for each of the six compounds. 

b. Name each of the compounds that are carbohydrates: either detailed generic or precise names accepted. Circle any that are not  "carbohydrates".

c. For each of the models that are carbohydrates, indicate if it is a mono-, di-, or polysaccharide and if it is a reducing or a non-reducing sugar. 


Compound A

Compound B

Compound C

Compound D

Compound E

Compound F
CHNO

II. Relative Sizes:

The diameter of a glucose molecule is about 10 Angstroms, a flu virus approximately 1,000 Angstroms (just below the viewing limit of a light microscope), a bacterium ~10,000 Angstroms and a red blood cell ~100,000 Angstroms.
 

a) Select two planets that reflect the proportional difference between the size of a glucose molecule relative to a virus.

b) Select three planets that reflect the proportional difference between the respective sizes of a virus, a bacterium and a red blood cell.

c) How many glucose molecules could be contained within: i) the space of a virus and ii) the space of a red blood cell?
(V = 4.189 r3) Show your respective calculations.
