Glyceraldehyde is an example of a(n) aldose, because it has three carbon atoms. 2. With the carbonyl group on the end of a six-carbon chain, the carbohydrate would be classified as a(n) aldohexose. 3. Any carbohydrate with the carbonyl group on the second carbon is a(n) ketose. 4. A monosaccharide is a(n) aldotriose if the carbonyl group is on the end of the carbon chain. 5. The most common carbohydrate, glucose, has six carbon atoms. 6. If a carbohydrate, like xylulose, has five carbon atoms and a carbonyl group on the second carbon, it is called a(n) ketopentose.

Question: complete the following sentences: aldohexose, triose,aldose, ketopentose, glucose, ketose.

Explanation:

Carbohydrate is one of the major classes of food which is divided into monosaccharide, disaccharide and polysaccharide. Monosaccharide is the simplest form of carbohydrates which is further divided into:

- glucose( the most common carbohydrate)

- fructose and

- galactose.

These monosaccharides can be further grouped according to the number of carbon atoms they possess and according to the functional group attached to its linear or unbranched carbon skeleton.

-TRIOSE: These are monosaccharides that has three carbon atoms example is Glyceraldehyde.

-ALDOHEXOSE: These are monosaccharides with the carbonyl group on the end of a six carbon chain.

- KETOSE: These are monosaccharides with the carbonyl group on the second carbon.

- ALDOSE: This is a monosaccharide in which the carbonyl group is on the end of the carbon chain.

-KETOPENTOSE: These are monosaccharides that has five carbon atoms and a carbonyl group on the second carbon. An example is xylulose.
