Hi, I would like to know why is there a hydrogen bond between an oxygen
molecule and distal Histadine in oxyhemoglobin. What I know is that a hydrogen
bond is a dipole-dipole interaction between a partial positive H and an
eletronegative atom with a partial negative charge. However there isn't a
dipole on an oxygen molecule. Thus how can the interaction between His and
oxygen be a hydrogen bond?
