Deoxyribose is a 5-sugar ring, with a similar composition as that of ribose. The main difference in composition between the two lies in the lack of hydroxyl (OH-) and introduction of a hydrogen atom that takes its place on the second carbon atom.

The deoxyribose sugar featured in DNA boasts a composition of 5 carbons and 3 oxygens and makes up the sugar-phosphate backbone which helps to hold the purines and pyrimidines (linked by hydrogen bonds) in the DNA double helix shape[1][2].
