Aren't ogliosaccharides a class of multi-ring sugar we can't metabolize, but bacteria in our large intestines can? Or is that not true of all ogliosaccharides?

There are some we cannot metabolize and some we can. Oligosaccharides present in human milk have been found to promote helpful bacteria in the growing child’s gut by bypassing our primary digestion. Oligosaccharides are also used on the outside of cells for cell recognition. The combination of different sugar chains on the outside of cells attached to proteins (collectively glycoproteins) are what give one their blood type. A B AB O positive and negative blood types are descriptors of what types of Oligosaccharides are present or not present.

Yep. Just to add for those curious to look it up, the attachment of carbohydrates to proteins is (usually) called glycosylation, which is why they are called glycoproteins.
