Difference Between Deoxyribose And Ribose

Ribose and Deoxyribose are monosaccharides with 10 hydrogen atoms and 5 carbon atoms. Both are simple sugars. They are aldopentoses. They undergo phosphorylation to form deoxyribonucleotide and ribonucleotide. The nucleotides act as the building block of nucleic acids and help them to carry genetic information. Pentose sugar for RNA is ribose with 5 carbon atoms. Pentose sugar for DNA is Deoxyribose. Ribose was discovered by Emil Fischer in the year 1891. Deoxyribose was discovered by Phoebus Levene in the year 1929. Some differences between Deoxyribose And Ribose based on structure, IUPAC name, molar mass, chemical formula, etc. are given below.
