Question 1

This compound is classified as a pyranose.

Accepted Answer

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

Question 2

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 3

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 4

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

Accepted Answer

Polysaccharides are indeed associated with energy storage and plant structure, while oligosaccharides are often found in glycoproteins.

Question 5

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.

Question 6

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

Accepted Answer

While it's true that potatoes are high in carbohydrates, they are also a good source of several important nutrients, including vitamin C, potassium, and fiber. As with all foods, moderation is key in a balanced diet, but potatoes can certainly be part of a healthy and nutritious meal plan.

Question 7

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 of a stereoisomer is depicted with the functional group (typically an -OH or -NH2) protruding towards the left. This is in contrast to the D form, where the functional group is on the right.

Question 8

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

Accepted Answer

The answer of The structure shown below is a $\beta$...
