This is a set of interactive tutorials which allow the user some control over what is displayed and permit experimentation and self-learning. By clicking on buttons and manipulating images information about molecular structures can be obtained and users are free to move at their own pace.

If you are new to these tutorials, there is a brief demo on how to use these learning aids. I strongly advise you visit this site first.

      In this set of tutorials, you will see some examples of the roles played by proteins in the body. You will learn that proteins are linear polymers of amino acids and they are joined by peptide bonds.

The tutorials are designed to be done sequentially so they should be done in the order shown here.

Protein Overview
Amino Acids
Polypeptides

      Far from being basic, the specific three-dimensional shape of a protein is complex. However, this compex overall shape can be broken down into basic regular structures which are found in most proteins.

This set of tutorials shows you how proteins are put together from these regular pieces of structure. Again, it would be beneficial to your understanding, to view the tutorials in the order shown below.

Secondary Structure
Tertiary Structure
Higher Order Organisation (Quaternary Structure)

      There are several other tutorials which you are able to look at though the internet. They have been created by a number of people, on different topics related to Biochemistry, all around the world. For an good index to these tutorials, go to Eric Martz Index Page.

This index provides an extensive list of structure-based tutorials which are available on the web and it is updated regularly. If you are interested in this area you should bookmark this index.
