I'm less sure about this stuff: Lipids (like phospholipids which make up the animal cell walls) are fats, and they are made of carbohydrates? Carbohydrates are molecules made of carbons and hydrogens. They are not polar (no polar covalent or ionic bonds) and don't really interact with water (hydrophobic). Protiens are strings of amino acids, which are folded by other protiens that float around in the cytoplasm of a cell based on mRNA?. Protiens do everything in a cell, and their shape is determined by the polarity of the amino acids that make them up. That's why protien folding as a computational problem is so important–because if we can determine the shape of a given amino acid string then we can design medicine faster (I love this kind of stuff). Enzymes are catalysts that speed up reactions. I don't remeber how they relate to other things.

Okay, that was 12 minutes. I'll now review the site and note updates that I would make to the previous brain dump. 1. Nice, she my scale models in! (Week 3) 2. Enzymes are protiens that help reduce the activation energy for a reaction, such as by locking the orientation of the reactants. Enzymes often need to be activated/deactivated and that happens when other molecules (protiens?) change or block the activation site. ```
