The molecular world is different from our macroworld because its structures are assembled and held together in a different way. There are no nails, pegs, glue, or solder; there are only forces due to charges. Molecular structures are shaped by charges that pull it together, hold it in position, or allow it to move.
If electrons on a molecule are more likely to be in one area, that part of the molecule will be negative, because electrons are negative.
If, on the other hand, electrons are less likely to be in an area, that area will be positive, because the nucleus is exerting its positive force here.
Negative areas attract positive ones.
But areas of the same charge repel.
We will explore how a biomolecule's properties, like charge, and its reponse to its surrounding, like water, determines its shape. We will develop a feeling for the qualities of shape and structure, the way molecules rotate, have active and quiet areas, have repeating units and some areas where everything is different, have cavities and high terrains.
These various qualities can give a molecule its strength or weakness, stability or impermanence, flexibility or rigidity, and even...its stickiness!
