MOBI

(Molecules of Biological Importance)

**Remember: all work for the quarter must be completed before enrichment will be counted.**

Objectives

Shown above are three models of biologically important molecules found in all living things and the foods we eat.

Skill 1: I can create 2D drawings of molecules, given the chemical formulas.

Skill 2: I can build 3D models of molecules, given the chemical formulas.

Skill 3: I can differentiate between MOBI drawings based on the elements they contain.

3D Building part of the lab

Come to our classroom for the next part. You will need to use one of my building kits.

Review of macromolecules - carbohydrates, lipids, proteins, and nucleic acids


Remember CHO-CHO-CHON-CHONP:

Carbohydrates - contain CHO (carbon, hydrogen, and oxygen)

Lipids (fats) - contain CHO (carbon, hydrogen, and oxygen)

Proteins - contain CHON (carbon, hydrogen, oxygen, and nitrogen and sometimes sulfur)

Nucleic Acids - contain CHONP (carbon, hydrogen, oxygen, nitrogen, and phosphorus)

Look at each of the figures below and tell me which macromolecule is represented by each.

You probably have two which are a little confusing, because both have only carbon, hydrogen, and oxygen. Do a little research and then come tell me how you can tell them apart.

Remember that this is enrichment, so it cannot hurt your grade; it can only help.

When you are finished, schedule a time to meet with me to review your lab and pictures. If you have a good understanding of the material, I will give you a short lab analysis to prove it.
