Biology 12

Today we discussed the fact that besides water there are four main types of chemical compounds in our bodies.  They are:  Carbohydrates, Proteins, Lipids (fats) and Nucleic Acids.   One thing they all have in common is that they are all polymers (chains of repeating units).  

We looked at how polymers are made:  By dehydration synthesis and how they are broken down into their small units:  By hydrolysis.

Next we looked in depth at carbohydrates and learned of some monomer and polymer names.

HOMEWORK:  Complete Section A part C) Biological Molecules of the Cell for tomorrow.

Second Block:  We did a lab on Antacid Buffers.   This will be due next Friday Feb. 10th.
