Hydrophilic molecules can bind with water, and thus they make up substances that can dissolve in water. Hydrophilic means "water loving," and hydrophilic molecules are receptive to water and are likewise in the polar group of molecules. With the majority of the electrons always resting on oxygen's side of the bonded H20 molecule, water is a polar molecule, and oxygen holds the negative side of the bond, while the hydrogens hold a positive charge. Now oxygen has all eight of its electron spots filled. Water is a polar molecule because H2O means there's two hydrogen atoms that can then form hydrogen bonds attached to the one stronger oxygen atom: oxygen has six electrons of its own, but it can hold onto eight, and so when two unsuspecting hydrogen atoms come along, each of them having just one electron to call their own, oxygen gathers them close and insists that they share.
That makes the molecule polar: one end is positive, with fewer electrons, and the other end is negative, hogging as many electrons as possible. One atom will be stronger and will pull negative electrons away from the other atom. Polar molecules are what form when two atoms from different elements come together to make an uneven compound. hydrophobic molecules, and the amino acids.
We'll start with the basics: polar molecules, hydrophilic vs. You may have run across this term and wondered what it meant-what are hydrophilic amino acids and what do they do? Hope you feel like brushing up on some basic organic chemistry, because this article's aim is to shed some light on the subject, and give you a quick chemistry refresher course on these important structures and molecules in our bodies.
