Metabolites are small simple structures absorbed in a diet. They include vitamins and essential amino acids. They can be used to construct more complex molecules or they can be broken down into simpler ones. Intermediary metabolites may be synthesized from other metabolites and often release chemical energy. For example glucose can be synthesized via gluconeogenesis (an anabolic reaction) to form starch or glycogen and can be broken down during glycolysis (catabolic reaction) to obtain chemical energy. End products of metabolism are excreted from the organism. Urea for example is an end product of protein degradation in man. Carbon dioxide is usually thought of as an end product of carbohydrate protein and fat degradation in aerobic organisms although technically carbon dioxide as carbonic acid can also participate in the biosynthesis of some substances particularly in plants. Catabolism and Anabolism Catabolism degradative metabolism involving the release of energy and resulting in the breakdown of complex materials (as proteins or lipids) within the organism. Anabolism the constructive part of metabolism concerned especially with macromolecular synthesis. Catabolism Anabolism =Metabolites and their pathways= =KEGG Pathways= is a resource database developed by the Kyoto University Bioinformatics Center dedicated to provide computational devices to aid the study on the genome are various areas in biomedical sciences. The database provide tons of diversified maps of various metabolic pathways in humans and in plants. In addition topics such as disease and drugs research are also mentioned and discussed in details with visual aids. Gene sequencing and ...
