After the Carbohydrates, Lipids and Proteins last week, we’re taking a closer look at Proteins and their structures.

Here is the class presentation – click the shadowed images for links to animations:

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.

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.
