sugar part than that of the aglycon moiety. In order to examine the influence of the carbohydrate pendent groups on the conformational preference of the N-glycosidic linkage with respect to Phi(N,) several models and analogs with gluco and manno configuration have been studied in the present work by computational chemistry. The crystal structure of XylbetaNHPr is reported here and its molecular packing
