Some radical queries

A little over 500 years ago, Vasco da Gama arrived on the west coast of Ind ia after the first direct sea voyage from Portugal with the intention of de veloping trade in spices, particularly in black pepper. Portugese took the merchandise, and much more; they ended up colonizing Goa. In 1999 delegates from all over the world came to this fabulous Goa for a symposium on antio xidants, some of which are natural products found in spices. Some views and queries on the interaction of antioxidants and radicals are presented. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
