Deoxyribosides are nucleosides that contain deoxyribose as their sugar component. A nucleoside itself is composed of a nucleobase linked to a sugar. In the case of deoxyribosides, the sugar is deoxyribose, a five-carbon sugar that differs from ribose by the absence of an oxygen atom at the 2' carbon position. The nucleobases commonly found in deoxyribosides are adenine, guanine, cytosine, and thymine.

These deoxyribosides are the building blocks of deoxyribonucleic acid (DNA). When deoxyribosides are linked together by phosphodiester bonds, they form the polynucleotide chains that constitute DNA. Each deoxyribonucleoside monophosphate unit within a DNA strand consists of a deoxyribose sugar, a nitrogenous base, and a phosphate group. The sequence of these bases along the DNA strand carries the genetic information of an organism.

The four main deoxyribosides found in DNA are deoxyadenosine, deoxyguanosine, deoxycytidine, and deoxythymidine. While deoxythymidine is almost exclusively found in DNA, the other three deoxyribosides can also be found in ribonucleic acid (RNA) as their ribose-containing counterparts (adenosine, guanosine, and cytidine). The presence of deoxyribose makes DNA more stable than RNA, which is crucial for its role as the long-term storage molecule of genetic information.
