Structural formula of a cyclic form of the pentose D-deoxyribose

Like D-ribose, D-deoxyribose has two cyclic or ring forms, deoxyribofuranose, with a five-membered ring, and deoxyribopyranose, with a six-membered ring. The form shown has a five-membered ring, so it is a deoxyribofuranose. Deoxyribose was discovered in 1929 by Lithuanian-American biochemist Phoebus Levene. (Public domain.)
