What Is The Difference Between An Aldose And A Ketose

In aldoses the carbonyl group is in the number one position.

Ketose is a monosaccharide whose carbon skeleton has a ketone group. An aldose is defined as a monosaccharide whose carbon skeleton has an aldehyde group. What is the difference between ketose and aldose. Carbohydrates containing keto co group are called ketoses.

Ketose is the monosaccharide that contains ketone group along with the carbon chain. Aldose structure has one carbon atom. Aldose is the monosaccharide that contains aldehyde group in its structure along with the carbon chain. In ketoses carbonyl carbon has number two.

This is also one of the primary reasons why those compounds are called ketones. The main difference between aldose and ketose lies in the fact that compounds belonging to the ketose group have a carbonyl group away from the end of the entire molecule. In general both aldoses and ketoses can be called monosaccharides. Both these monosaccharides can easily be distinguished through seliwansoff s test.

Ketoses form hemiketal rings and aldoses form hemiacetal rings. Aldoses are monosaccharides with an aldehyde group. Ketose and aldose are monosaccharides which can be differentiated based on the group they contain. The core difference between aldose and ketose is that aldose contains an aldehyde group in each unit while ketose contains a ketone group.

This is the main difference between aldose and ketose. Ketose structure has three carbon atoms. They are further classified according to the number of carbon atoms in the chain as ketotriose 3 carbon atoms ketotetrose 4 carbon atoms ketopentose 5 carbon atoms ketohexose 6 carbon atoms etc. They are primarily found in plants.

Therefore aldoses are monosaccharides containing aldehyde groups at the end of the carbon chain whereas ketoses are monosaccharides containing ketone groups in the carbon chain.
