1. The two molecules shown are: A. Epimers B. Identical molecules just drawn differently C. Anomers D. Oligomers C. Enantiomers

2. Sphingomyelins contain more saturated fatty acid tails than glycerophospholipids. A. True B. False 3. What 2 sugars comprise maltose? What kind of bond links the 2 sugars? (open answer) 4. Which of the polysaccharides in the attached figure represents the protective exterior of insects, crabs, etc.?

Expert Solution

1. Image not shown, so you can take the hint from their definitions.

Those stereoisomers which are different in its configuration at only one chiral carbon atom are called as Epimers.

oligomer is a molecule that consists of a few monomer units.

Anomers are cyclic monosaccharides or glycosides that are epimers, differing from each other in the configuration of C-1 if they are aldoses or in the configuration, at C-2 if they are ketoses.

Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another.

2. true

Sphingomyelin consists of a phosphocholine head group, sphingosine, and a fatty acid. It is one of the few membrane phospholipids not synthesized from glycerol. The sphingosine and fatty acid can collectively be categorized as a ceramide. On the other hand, glycerophospholipid contains saturated fatty acid in the first position.

3. Maltose is made up of two glucose molecules.

Two molecules of glucose are linked by an α-1,4-glycosidic bond to form the disaccharide maltose.

4. Chitin (image not shown)

Bulbs A, B, and C in the figure(Figure 1) are identical and the switch is an ideal conductor. How does closing the switch in the figure affect the potential difference? Check all that apply. Hints Check all that apply. The potential difference across A is unchanged. The potential difference across B drops to zero. The potential difference across A increases by 50%. The potential difference across B drops by 50%.
