Non-polar covalent bonds result when the sharing is
equal or the molecule is symmetrical, thus canceling the
polarity.
   e.g. CO2, long chain hydrocarbons
Hydrophobic – “water fearing” – repels water and orients
away from water and aqueous solutions.
The hydrophilic and hydrophobic nature of proteins and
other molecules plays a large role in the conformation
(shape) and position in cell membranes and other
structures, as well as their functions. Interactions form
between molecules and groups of like polarity or non-
polarity.
