Question 1

The following Haworth projection was drawn from the open chain form of a ketose.

Accepted Answer

The answer of The following Haworth projection was drawn from...

Question 2

Where polysaccharides are most often associated with energy storage and plant structure,oligosaccharides are commonly portions of glycoproteins.

Accepted Answer

Polysaccharides like starch and glycogen are commonly used for energy storage in plants and animals, while others like cellulose provide structural support. Oligosaccharides, on the other hand, are often found as part of glycoproteins, which are proteins with attached carbohydrate molecules that serve various functions in the cell.

Question 3

The structure shown below is a $\beta$anomer.

Accepted Answer

The structure is a six-membered ring with an F1F1F1S1β-F1F1F1O- glycosidic bond, indicating a β-anomer. The alphanumeric code following the structure is not relevant to answering this question.

Question 4

One can expect that a D enantiomer will rotate polarized light to the right (+ direction).

Accepted Answer

The designation of a molecule as a D-enantiomer (based on its relation to glyceraldehyde) does not necessarily predict the direction in which it will rotate polarized light. The actual direction of rotation (left or right) is an empirical property and must be determined experimentally.

Question 5

The L form of a stereoisomer has an -OH on the left in the Fischer projection.

Accepted Answer

In the Fischer projection, the L form stereoisomer has the -OH group on the left side, while the D form has the -OH group on the right side.

Question 6

Potatoes,being high in carbohydrates and low in other nutrients,should only be consumed in very small quantities.

Accepted Answer

While potatoes do contain a high amount of carbohydrates, they are also a good source of vitamin C, potassium, and fiber. Consuming them in moderate amounts as part of a balanced diet is perfectly fine.

Question 7

This compound is classified as a pyranose.

Accepted Answer

The answer of This compound is classified as a pyranose....

Question 8

Worldwide,the major use of glucose is for energy storage.

Accepted Answer

The major use of glucose worldwide is as an energy source for cells, not for storage. Energy storage in organisms is typically achieved through compounds like glycogen in animals and starch in plants, both of which are polymers of glucose.
