Description |
Metal ions play important roles in human life as cell components as well as materials. Accordingly, understanding chemistry is essential in our life. In this talk, first I would like to introduce the world of chemistry to general people by focusing on heavy metal ions in life. Second, I would like to explain basic ideas for elucidating functional mechanisms of these metal ions. Finally, one of powerful techniques for investigating structure-function relationships of metallo-proteins, Raman spectroscopy found by Sir C.V. Raman, is explained, and a few examples of concrete results will be surveyed. Practically, the talk will consist of (1) What is ‘molecule’?, (2) Atoms are vibrating in a molecule (permanent motion), (3) Protein is a kind of molecules, (4) There are various metallo-proteins with different functions, (5) Raman spectroscopy can elucidate working mechanisms of metallo-proteins, and as examples, some practically important results from hemoglobin, respiration enzymes, gas sensor proteins, etc. will be demonstrated. |
