Although we are learning this in the Chemistry of Life unit, it is actually part of the SL Option C and HL additional material, so look for the book chapters in the right place!

Essential Biology 7.5 & C1: Proteins

Proteins:

Life Cycle of a Protein from Sumanas

Making polypeptides from John Kyrk

Check that you know the different levels of protein structure, including the roles of hydrogen bonds and disulfide bridges. Think about how the properties of the R-groups on amino acids cause the protein to fold up in a set configuration.

FoldIt!

Make sure you can give examples of fibrous and globular proteins and that you can name some examples of uses of proteins that are not structural or related to the plasma membrane.

And don’t forget to play FoldIt – the brilliant protein puzzle that helps medicine!
