In the first section of this page, you will write a daily summary of that day's class.  For example in  your chapter 2 blog, your first entry should be titled 9/3/10.  You should then write a one or two paragraph summary of that day's lecture, outlining the major points.  In the second section, you are required to add two items (link to a website, video, animation, student-created slide show, student-created PowerPoint presentation) and one journal article pertaining to a topic in this chapter.  A one-paragraph summary must accompany each item describing the main idea and how it applies to the lecture topic.  Please see the PBWorks help guide for assistance embedding video and other items directly in the page.  I will also produce a how-to video on using tables to wrap text around items and other useful tips.  Please see the syllabus for organization and grading details.

A.  Daily Blog

9/10/10: Today in class, we started off by doing a poll asking "why carbon?".  After that, we went on to discuss all the different types of functional groups.  Each type of functional group exhibits the same properties in all molecules in which it occurs.  They are carbonyl, carboxyl, hydroxyl, hydroxyl, methyl, phosphates, and sulfates.  In a carbohydrate, for every carbon, there are two hydrogens and for every two hydrogens, there is one oxygen (1:2:1 ratio).  OH is usually targeted in chemical reactions.  A ketone has carbon on each side to bilud off of.  Aldehyde cannot bond on the side because hydrogen is monovalent.  Then we talked about enantiomers.  We left off with how carbohydrates are stored in animals and animals cannot break down cellulose.  Cellulose is also known as fiber.

9/15/10: We started off the lecture by talking about proteins.  Proteins are composed of carbon, hydrogen, nitrogen, and small amounts of other elements.  Amino acids make up proteins.  Then we discussed how the presence of a hydroxyl group means that it is polar.  Anything endingn in "acid" or "-ate" is an acid.  The suffix "-ine" means that it is polar.  Hydrogen bonds help polar bonds participate in interactions.  The core of amino acids can participate in hydrogen bonds.  Dehydration synthesis links amino acids together.  Proteins always extend at the c-terminus.  Proteins fold to shield their hydrophobic residence.  Then we talked about the four different types of structures: primary, secondary, quaternary, and tertiary.  We ended the lecture by stating that disuphide linkages are the strongest bonds.

9/17/10: Today, we read about an experiment that was done that showed proteins contain all the information needed to fold into their correct 3-D shapes.  We worked in pairs, which helped a lot because we were able to discuss and analyze the experiment. I usually find that working in groups helps me learn. It takes me a while to figure out concepts on my own. Each group had to go into detail on a certain part of the experiment. I learned that first, the ribonuclease needs to be denatured. This is done by breaking the H bonds and the ionic bonds. After that, the B mercathethanol (spelling?) and the urea have to be separated from the RNA. Once that is done, you can see that the proteins really do contain all the information needed to fold into their correct 3-D shapes.

This is a link to a website that explains functional groups.  It shows what each functional group looks like and names them all.  It pertains to what we learned this week so I think it will help a lot.

This is a link to a website that explains proteins.  We focused on proteins this week so I think it would help with the lesson.

This journal pertains to the lesson because it talks about hydrogen bonds which were mentioned a lot in the lesson.
