Metabolome

Alberta scientists map human metabolome chemicals: "The researchers on Wednesday said the Human Metabolome Project, led by the University of Alberta, has listed and described some 2,500 chemicals found in or made by the body (three times as many as expected), and double that number of substances stemming from drugs and food. The chemicals, known as metabolites, represent the ingredients of life just as the human genome represents the blueprint of life."

More readily manipulated, understanding the role of different metabolites could lead to massive advances in treatment options.
