Since the oxygen in the OH group is highly electronegative, it hogs all of the electrons and a positive charge is created on the hydrogen side of the group. That side then forms a hydrogen bond with the negatively charged oxygen on the phosphate group.

WebBoth these effects were imputed to hydrogen bonding between CDs and phospholipidic bilayer′s head groups .
