Chromophores in biological environments<br />
Xabier López<br />
Kimika Fakultatea; Euskal Herriko Unibertsitatea<br />
An introduction of chromophores in biological environments will be given. Biochromophores<br />
that absorb in the visible lighth mainly consist of phrostehtic groups or cofactors covalently bound<br />
to proteins. In this lecture, we will see some basic examples of these phrostethic <strong>org</strong>anic molecules<br />
and how the absorption of light is coupled with their complex biological functions. In addition,<br />
and since the optical response of these phrosthetic groups is often modulated by their proteic<br />
environment, an introduction to protein structure and its modelization will be given. Finaly, we<br />
discuss some illustrative examples of chromophores emdebbed in proteins and how their optical<br />
absorption is a consequence of both chromophore chemical nature and interaction (structural and<br />
electrostatic) with its proteic surroundings.<br />
