5-脱氧-L-核糖, 5-Deoxy-L-ribose

5-Deoxy-L-ribose is found in a variety of organisms, including humans. It is stereoselective, with the (-) form being more common than the (+) form. 5-Deoxy-L-ribose is synthesized by the glycosidic bond between l-arabinose and D-ribose. This compound is an inexpensive way to produce 5-deoxy analogs of other sugars, such as glucose, fructose, and mannose. The biosynthesis of 5-deoxy-L-ribose relies on a molybdenum cofactor and involves oxidation of L-arabinonate by aldehyde oxidase to give L-xylulose. Lactate dehydrogenase converts this into D-xylulose. Dihydroorotate reductase then reduces this to give D-(+)-5--deoxy--D--erythro--pentitol phosphate.

5-deoxy-L-ribose is a sugar derivative that has generated significant interest in the scientific community due to its unique physical and chemical properties. This article will provide a comprehensive overview of 5-deoxy-L-ribose, focusing on its definition, physical and chemical properties, synthesis and characterization, analytical methods, biological properties, toxicity and safety in scientific experiments, applications in scientific experiments, current state of research, potential implications in various fields of research and industry, limitations and future directions.
