2-Deoxy-β-D-erythro-pentopyranose

Description:
2-Deoxy-β-D-erythro-pentopyranose, commonly referred to as 2-deoxy-D-ribose, is a pentose sugar that plays a crucial role in biochemistry, particularly in the structure of nucleotides and nucleic acids. This compound is characterized by the absence of an oxygen atom at the second carbon of the ribose sugar, which distinguishes it from ribose. It exists predominantly in a cyclic pyranose form, exhibiting a six-membered ring structure. The molecule is typically found in its β-anomeric form, where the hydroxyl group on the anomeric carbon is oriented upwards in the Haworth projection. 2-Deoxy-D-ribose is soluble in water and has a sweet taste, similar to other sugars. It is a vital component of DNA, as it forms the backbone of the DNA structure when combined with phosphate groups and nitrogenous bases. Additionally, it is involved in cellular metabolism and energy production, particularly in the synthesis of ATP. Its CAS number, 22900-10-3, is used for identification in chemical databases and regulatory contexts.
