Abstract
THE lability to acid of purine ribomononucleotide N9-glycosidic linkages, as opposed to the stability of pyrimidine ribomononucleotide N3-glycosidic linkages, is well documented (for example, ref. 1). It has, however, been noted that the latter linkage is not completely resistant, in the cases of cytidylic and uridylic acids, under the conditions of the Bial reaction of their pentose moieties with orcinol2.
