Abstract

Although reindeer milk is utilised as a food in some areas in the world, including Mongolia, the saccharides in this milk have thus far not been explored. In this study, the structures of the separated saccharides were characterised by 1H-nuclear magnetic resonance spectroscopy to be as follows: Gal(β1-3)Gal(β1-4)Glc (3'-galactosyllactose, 3'-GL), Gal(β1-6)Gal(β1-4)Glc (6'-galactosyllactose, 6'-GL), Gal(β1-4)Glc (lactose), Neu5Ac(α2-6)Gal(β1-4)Glc (6'-N-acetylneuraminyllactose, 6'-SL), Neu5Ac(α2-6)Gal(β1-4)GlcNAc(β1-3)Gal(β1-4)Glc (sialyllacto-N-tetraose c, LST c) and uridine 5'-diphospho-α-N-acetyl-D-glucosamine (UDP-GlcNAc). In addition, monosaccharide-α-1-phosphate and some other UDP-mono or oligosaccharides were found, but Neu5Ac(α2-3)Gal(β1-4)Glc (3'-N-acetylneuraminyllactose, 3'-SL) was not detected. Lactose was the predominant saccharide. It may be concluded that, in this milk, the concentration of phosphorylated or UDP-saccharides was higher than that of Neu5Ac containing oligosaccharides; this should be a significant feature of this species milk.
