Radicais livres de oxigênio: um software introdutório

Though Free Radicals is one of the most frequently explored scientific subjects in mass communication media, the topic is absent of many Biochemistry introductory courses, especially those in which the students do not have a good chemical background. To overcome this contradictory situation we have developed a software treating this topic in a very simple way. The software is divided in four sections: (1) definition and description of free radicals, (2) production pathways, (3) mechanism of action and (4) enzymatic and non enzymatic protection. The instructional capacity of the software has been both qualitative and quantitatively evaluated through its application in undergraduate courses. The software is available in the INTERNET at the site: http://www.unicamp.br/ib/bioquimica/ensino.
