Lactodifucotetraose
Human milk oligosaccharides are characterised in infant nutrition research and in studies of gut microbiology, and Lactodifucotetraose belongs to that family of structures. The molecule consists of a lactose core carrying two fucose residues, corresponding to formula C24H42O19 and a molecular weight of 634.58. It is a white powder used by analytical groups as a qualitative identity marker when profiling oligosaccharide mixtures, as a retention-time reference in HILIC or porous graphitic carbon separations, and as a calibrant for quantitative work on milk-derived samples. Pack sizes offered for this item cover 1 mg, 5 mg, 10 mg, 25 mg and 50 mg. Recommended storage is -20 +/- 5 C, and shipment is arranged with ice packs.
