Heterochiral ApAs (ALpAD and ADpAL) together with homochiral D-(ApA) and L-(ApA) were synthesized and their helical structures were investigated by using spectroscopic techniques. The results indicate that the chirality of the 3'-end residue is the primary determinant for the helical sense of adenylyl-(3'-5')-adenosine (ApA).
