A nucleic acid constituent (see illustration) of all animal, microbial, and plant cells; also known as 2- d -deoxyribose. Deoxyribose is enzymically formed in living cells by reduction of ribonucleoside di- or triphosphate. The four deoxyribose nucleotides, containing adenine, guanine, cytosine, and thymine, are the major constituents of the deoxyribonucleic acids (DNA), which control the hereditary characteristics of every living organism.
