What knowledge have you connected with past knowledge?

So far in the course we have studied the properties of water, amino acids and proteins, proteins as enzymes and enzyme mechanisms. Most everything we have covered I have been taught in other science courses. The importance of hydrogen bonding, R-groups, and structure of molecules was covered in organic chemistry. Lipids, proteins, and amino acids were discussed in biology. So far this semester it has been a review, but it is nice to have a little refresher at the beginning to make sure that we understand the basic concepts before moving on to the more complex topics.
