    Zu viel Sonne schadet nicht nur Menschen, sondern auch Pflanzen. Pflanzen haben jedoch im Gegensatz zum Menschen ein besonderen Schutzmechanismus entwickelt. Wissenschaftler desBiodesign Instituts der Arizona State University wissen, dass Biomolekuele, wie etwas Cartonoide dafuer verantwortlich sind.


Carotinoide (Carotenoids) funktionieren wie “Kabel”, die die Energie des Sonnenlichts abtransportieren. Die geschieht in der Form und ungewollten Elektronen, die lange Wege transportiert werden und somit kein Schaden an der Pflanze anrichten koennen. Photoprotektion funktioniert nach derzeitigem Stand in der Weise, dass das Carotinoid oxidiert und somit ein Elektron verliert.
