Protein Circular Dichroism Data Bank

Proteins are tiny little machines that do really important work in our bodies. Scientists want to understand how they work, so they study them. One way they study them is by shining a special kind of light called "circularly polarized light" at the proteins. This light makes the protein molecules twist and turn in a certain way, which scientists can measure.

A "data bank" is like a big library where scientists can store all the information they have collected about protein molecules when they shone this special light on them. They can use this data to compare different protein molecules and learn more about how they work.

So, the Protein Circular Dichroism Data Bank (PCDDB) is an online library where all this information is stored. Scientists can go to the PCDDB website, look up information about specific protein molecules, and learn more about how they twist and turn in response to circularly polarized light. This helps them understand how proteins work, and can lead to new discoveries and treatments for diseases.
