Here are some exercises to help you understand the week 2 objectives
Be able to identify carbons and hydrogens in organic compounds
Watch this video
Be able to determine whether 2 structures are isomers and whether they are structural, geometric or enantiomeric isomers.
For 2 structures to be isomers, they have to have the same molecular formula
Watch the video. Note that geometric isomers are a type of diastereomers. Geometric isomers are distinguished by having a double bond and a different arrangement of atoms around he double bondd
Be able to identify functional groups.

Be able to recognize and give functions for the following biomolecules: Monosaccharides, disaccharides, polysaccharides. Fats, phospholipids, steroids. Amino acids, proteins.
The following exercise will help you recognize the key differences between carbohydrates and lipids.Click on the green flag and observe which structures are lipids and which are carbohydrates.
Click next and then click the appropriate button
Continue hitting next and choosing the correct button
Here is a second activity for carbs and lipids
Be able to distinguish primary, secondary, tertiary and quaternary structure
This can be difficult for people to remember. A few key points
- The levels represent interactions within a protein. They do not necessarily represent steps in protein folding .
- You should know (1) What types of bonds are used and (2) What parts of the amino acids are involved. Be sure you can identify R groups and the backbone portions of amino acids.
