BILD 1 Lecture Notes - Lecture 3: Bild, Weak Interaction, Partial Charge
Document Summary
Bild 1 ~ lecture 3 ~ 10/3/2018 ~ wednesday. Chemistry is the foundation of all interaction. Covalent strong , stable, shared electrons example h20, not necessarily shared equally, could be more pulled to someone, polar covalent bonds. Hydrogen bonds ( non-covalent) relies on partial charge, interaction between an electronegative atom and a h that is bound to an electronegative atom. Second weak interaction is ionic interactions, in context of aqueous environment these are weak, positive and negative attracted but weak. In hydrophobic molecules not interacting with water. Forces water in a more ordered state. Thinking about hydrophobic effect, in aqueous solutions hydrophobic molecules will cluster together they can be more disordered , this is energetically less favorable, entropy of water increase. Hydrophobic things in aqueous will come together , water excluded so its disordered. Life is carbon bases , can form bonds with h, o, n and another c. Main molecule of life: lipids, nucleic acids, carbs, proteins.
