Question

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.

Answer 1

Answer:

1. Glyceraldehyde is an example of a aldotriose 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 aldohexose
3. Any carbohydrate with the carbonyl group on the second carbon is a ketose
4. A monosaccharide is a aldose 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 ketopentose.

Explanation:

1. aldotriose: it is a monosaccharide having both aldehyde and a three carbon atom, e.g glyceraldehyde
2. aldohexose: a monosaccharide having both an aldehyde group and 6 carbon atoms(hexose) e.g dextrose
3. ketose: a monosaccharide with a carbonyl group attaches, e.g dihydroxyacetone
4. aldose: is a type of monosaccharide  that contain aldehyde functional group, with two or more hydroxyl group attached,one of the hydroxyl groups is at end opposite to the aldehyde.e.g glyceraldehyde, ribose etc
5. glucose: simple sugar with molecular formula $C_{6}H_{12}O_{6}$, most abundant monosaccharide
6. ketopentose: a monosaccharide containing both ketose and 5 carbon atoms (pentose), e.g D-ribulose

5) glucose

6) ketopentose

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.
