Water pair interaction geometries with N-acetylamines (α-/β- GlcNAc and α-/β- GalNAc). Interaction (a) has the C1-H1 vector collinear with the water HOH angle bisector; and interaction (b) has the C2-H2 vector collinear with the water HOH angle bisector. All molecular graphics were prepared with VMD155.
