Re: Are carbohydrates hydrophobic?

Carbohydrates are Hydrophilic. They have large amounts of oxygen and therefore, polar molecules, according to “Carbohydrates (1)”. Polar means that the molecules have "dipoles". This is due to the unbalanced charge of electrons in either part of the molecule. Remembering the principle that...

However, when it divides, the 2 DNA strands seperate and then it loses it's hydrophobic properties. My theory ...
