Carb and Lipid Test

Be able to distinguish primary, secondary, tertiary and quaternary structure

This can be difficult for people to remember.  A few key points

1. The levels represent interactions within a protein. They do not necessarily represent steps in protein folding .
2. 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.

Here is a protein structure review

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.
