biochemistry!

The most important thing to know is that matter consists of chemical elements, and these elements are the starting point of compounds. Knowing that, we can say that atomic structure determines the behavior of an element. Knowing the behavior of an element helps determine whether an element will bond covalently or by ionic depending on the type of element, valence electrons and electronegativity. Polar and nonpolar compounds help determine why or how a certain compound is hydrophilic or hydrophobic. The reason why water is so important is because it is the universal solvent, it has a neutral pH, and it's weak hydrogen bonds ( the polarity of water results in hydrogen bonding) make it possible to have cohesion and adhesion because of it's easy breaking of the bonds. Carbon plays a very important role in chemistry because of it's versatility, because of it's shape it is able to bond with many other elements and itself. The differences in carbon skeletons contributes to the diversity of organic molecules. Also, functional groups give the overall molecule distinctive chemical properties. Macromolecules are especially important because it contains things like carbohydrates, lipids, proteins, and etc. Carbohydrates acts as field and building material. Lipids are able to store large amounts of energies, and actually help with growth( steroids). There is also DNA which stores and transmit hereditary information, thus relating to the major theme evolution.
