Ribose: This is another type of sugar found in RNA (ribonucleic acid). Unlike deoxyribose, ribose has an additional oxygen atom attached to one of its carbon atoms.
Pentose Sugar: Deoxyribose and ribose both belong to a class of sugars called pentoses because they have five carbon atoms.
Nucleotides: Sugars combine with phosphates and nitrogenous bases to form nucleotides, which are the building blocks that make up DNA and RNA. Each nucleotide contains a sugar molecule, phosphate group, and nitrogenous base.
