Biochemical processes in organisms are considered as verylarge networks consisting of reactants, products and enzymes with interconnections representing reactions and regulation. Examples are given bythe well known Boehringer poster [4] and the Biochemical Pathways atlas [5]. These networks are very complex and grow fast bythe steadyprogress 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 [7] based on Graphlet [2].
