Question

Human milk contains the oligosaccharide 2′-fucosyllactose (α-L fucose-(1→2)-β-D-galactose-(1→4)-D-glucose), which may help protect the newborn from bacterial infections. Draw the structure of this oligosaccharide.

Short answer

Human milk contains the oligosaccharide 2′-fucosyllactose in the form of free and conjugated arrangement in structure which helps in prevention of infection and also develop the immune system.

Step-by-step solution

2’fucosylllactose

2’fucosylllactose oligosaccharide is made with molecules of α-L fucose-(1→2) linkage with β-D-galactose-(1→4) linkage with D-glucose with repeating units.

Human milk

In human milk oligosaccharides of 2’fucosylllactose form a compact structure and inhibit pathogen entry.

Human milk containing the oligosaccharide 2′-fucosyllactose help in preventing bacterial infection.
