The difference between an aldose sugar and a ketose sugar is . Group of answer choices the ring form and the linear chain the number of carbon atoms the position of the carbonyl group the position of the hydroxyl groups

position of the carbonyl carbon

Explanation:

In the linear structure of sugars having an aldehyde group, are called aldoses, and sugars having a keto group are called ketoses.

Like adehydes H-C=O the carbonyl carbon is the first/last in the chain it is bounded to Hydrogen, double bounded to oxygen and a single bond to the chain. An aldose linear sugar like D-glucose have the carbonyl carbon as it first carbon.

But ketones R-COR the carbonyl carbon is in between the chain, it is bounded to two carbons on both sides. Like D-fructose the keto carbon is the second carbon.

In a open ring structure the 1st carbon, adehyde group is condensed with the hydroxy group (OH) of the 5th carbon forming a ring. The first carbon is now bound to the chain, Hydrogen, OH and oxygen which forms the ring.

In the keto open ring structure of D-fructose, the second carbon(keto group) is condensed with the OH of the 5th carbon
