polar amino acids

When electrons are shared between atoms of different elements, the electrons are not shared equally, resulting in a polar bond in which the increased-probability cloud over one atom has a slightly negative charge (delta -)while that over the other atom has a slightly positive charge (delta +). This unequal sharing generates a dipole. Molecules with dipoles tend to align positive toward negative.
