Biochemical processes in organisms are considered as very large networks consisting of reactants, products and enzymes with interconnections representing reactions and regulation. Examples are given by the well known Boehringer poster  and the Biochemical Pathways atlas . These networks are very complex and grow fast by the steady progress of knowledge in life sciences.
BioPath is the result of the Electronic Biochemical Pathways Project [1,3], a joint work of research groups at the universities of Erlangen, Mannheim, Passau and Spektrum Verlag, Heidelberg. BioPath provides a convenient electronic access to biochemical reactions at a high level of detail and explores all advantages of an electronic version over a printed one. It uses an innovative algorithm for drawing directed graphs  based on Graphlet .
