D-Mannose, identified by CAS number 3458-28-4, is a naturally occurring monosaccharide and a C-2 epimer of D-glucose. It is a vital hexose sugar that plays a significant role in human metabolism, particularly in the glycosylation of proteins. Physically, it typically appears as a white crystalline powder or colorless crystals, exhibiting high solubility in aqueous environments and a characteristically mild, sweet flavor.
In industrial and research settings, D-Mannose is valued for its specific chemical reactivity and its role as a precursor in various biochemical pathways. It is widely utilized as a starting material for the synthesis of complex carbohydrates and specialized chemical intermediates. Due to its hygroscopic nature, it requires careful storage in tightly sealed containers to maintain its structural integrity and prevent clumping during handling.
