Question

compare the molecular structure of glucose and fructose.​

Answer 1

Answer:

Explanation:

Both are hexose sugars, i.e. have 6 carbons in their structure.

However, glucose is an aldohexose, whereas fructose is a ketohexose. This means that the functional group present in these sugars is an aldehydic and a ketonic group respectively.

Another difference is that in glucose, the anomeric carbon is the first carbon, whereas in fructose, the anomeric carbon is the second carbon. The anomeric carbon is the one containing the carbonyl group, which reacts to form the cyclised structure.

Answer 2

GLUCOSE

1) Also known as grape sugar.

2) Six-membered ring.

3) The preferred energy source for the body.

4) Less lipogenic.

5) Less fat producing.

6) Relies on hexokinase/ glucokinase for

initiating metabolism.

7) It is an aldohexose.

8) Forms a pyranose ring structure.

FRUCTOSE

1) Also known as fruit sugar.

2) Five-membered ring.

3) Not the preferred energy source for brain and

muscles.

4) More lipogenic.

5) More fat producing.

6) Relies on fructokinase for initiating metabolism.

7) It is a ketohexose.

8) Forms a furan ring structure.
