Friday was a research class for the unit 1 application project. If you were absent, be sure to let me know which molecule you are researching. Remember, this report is due in two weeks (the 20th). Have a great weekend!

Today we discussed the unit 1 application project that we will begin working on tomorrow. We then went over carbohydrates and lipids. There are a collection of textbook questions to answer for homework...due Monday. Research class tomorrow.

Today we went over acids, bases, the pH scale and buffers. We focused on the bicarbonate-carbonic acid blood buffer system. We then began a study of the macromolecules. We discussed some common functional groups and carbohydrates. This will continue tomorrow. Here is a link to a site I will be using tomorrow. It shows the relevant structures.

Today we began by discussing last night's homework. We then went through the "Biochem 2" note. Topics discussed included molecular shapes and polarity, intermolecular forces, hydrophobicity and the unique properties of water. There is homework tonight. For details see under the Homework heading next to these posts.

Today we started the "Biochem" portion of the first unit, Metabolic Processes, of the course. We reviewed some basic chemistry concepts and terms and then disscussed isotopes and radioisotopes. We then went over how to determine types of chemical bonds based on electronegativities. There is reading and questions for homework. These will be discussed tomorrow. Homework is listed in the right side bar.

Here's some help with the chemistry stuff in this first unit. Some of you may need to do some extra work during this section in order to understand the chemistry component.
