1. Name as many different classes of compounds for which fatty acids are used as building blocks and how many fatty acyl chains occur in the compound?

2.Use words to distinguish between the following pairs of carbohydrates shown below.

Among the words you can use are:

-compositional isomers (to distinguish aldoses and trioses -- such as dihydroxyacetone and glyceraldehyde)

-enantiomers (to distinguish D and L forms of a compound)

-diasteriomers and anomie's
a. D-glucose and D-galactose
b. D-glucose and D-glucopyranose
c. D gluocse and L glucose
d. D glucose and D fructose
e. alpha-D-galactopyranose and beta-D-galactopyrnose

3. add the 10 reactions of glycolysis to get or prove the net (overall) reaction for glycolysis. To get the right answer you have to "multiply by 2" starting with reaction 6 of glycolysis.

So, write out all 10 reactions -- each on a separate line, complete and balanced.
Then, either strike out compounds that occur as both reactants and products and add up the rest. OR, you can accumulate all reactants to the left of an arrow and all products to the right of an arrow and then eliminate all reactants and products in common, showing the result as the final, net or overall reaction of glycolysis.
