Carbohvdrates have many impor-tant biological functions in organism. It hasbeen demonstrated that structural characteris-tics of carbohvdrates provide important cluesfor the understanding of cell and moleculerecognition process where sugar is mainly in-volved in. It is concentrated on the concepts ofoligosaccharide structure,the latest theoreti-cal development of this subject,as well assome methods often used in this field.It isgenerally considered that one of the theoreticaldirections is to exhibit the int...
