Why is deoxyribose classified as a nonosaccharide?

Question

Thanks!

Answer 1

nonsaccharide??

its because it is a protein syntheses not a sugar syntheses  

Answer 2

I believe you meant, Monosaccharide and that is because it only contains ONE sugar.  If it was di or polysaccharide, the it would have two or multiple sugars, respectively.  

Answer 3

This question is more of a definition question. A monosaccharide is a sugar which is unlinked to another sugar. Glucose is an example of a monomer (mono = one, saccharide= sugar)

ribose, similar to glucose, is a 5 carbon based sugar. (Glucose is 6 carbon) Deoxy-ribose is just ribose sugar less an oxygen atom.

Before making a chain each deoxyribose molecule would be considered a sugar monomer; aka a monosaccharide. the glycosidic bond of the DNA changes this fact however. After bonding it is known as a polymer

*extra note - dimers are 2 monomers linked together. For example the monosaccharide gluose can be linked by a glycosidic bond. Depending on the nature of how the bond is connected it can form the dimer of lactose; the sugar present in milk.

Answer 4

Deoxyribose has only 5 carbon atoms. It is a simple sugar. It is a monosaccharide.
