I think in general, a balanced combination of all macromolecules is important to sustain a healthy diet; however, I can see where certain macromolecules need to be prioritized more in diets. In a keto diet, fats are prioritized while carbs are demphasized, so the body's metabolism will shift from carbs to fats. I think its interesting how many choices we can make to fuel our bodies in certain ways to produce different outcomes/benefits.

I think this is a good example of how structure affects function; even the slightest difference in their composition can change the identity of the sugar, although they both belong to the hexose group.

The saturated fatty acid character at room temp. consists of straight carbon chains that are packed tightly together, thus forming a more rigid and compact structure. Vegetable oil likely contains more desaturated fatty acid character, with more double bond "kinks" in the hydrocarbon thus forming a less compact and more viscous structure.

Due to the hydrophobic nature of lipids/nonpolar compounds, this made me wonder about the composition of soap. I wonder how the nonpolar + polar properties interact in soap so that it still interacts with water, but not the extent of complete repulsion or dissociation in water.
