Where can I find structures of oligosaccharides and homo/heteropolysaccharides?

[Pioneer]

I'm looking for structures of ogliosaccarides and homo/heteropolysaccharides but I seem to not be able to come across any. I did searches and checked texts but unfortunately they weren't very helpful. So, can anyone tell me where I find such structures, possibly online? Thanks.
