Welcome to the Metabolism portal. Metabolism is the modification of biological chemicals by a complex network of enzymatic chemical reactions which occur within the cell. Metabolic processes are vital for life, they provide the raw ingredients for all cell processes, including protein biosynthesis and DNA replication, produce energy for the cell in the form of ATP and breakdown harmful substances such as ethanol. Metabolism is broken down into many separate interconnecting metabolic pathways for ease of study. Metabolism is a field within biochemistry and molecular biology. A summary of the major metabolic pathways. Major compounds are shown in black text in white boxes, and metabolic pathways are shown as text links. Glucuronate metabolism Pentose interconversion Inositol metabolism Cellulose and sucrose metabolism Starch and glycogen metabolism Other sugar metabolism Pentose phosphate pathway Glycolysis and Gluconeogenesis Amino sugars metabolism Small amino acid synthesis Branched amino acid synthesis Purine biosynthesis Histidine metabolism Aromatic amino acid synthesis Pyruvate decarboxylation Fermentation Fatty acid metabolism Urea cycle Aspartate amino acid group synthesis Porphyrins and corrinoids metabolism Citric acid cycle Glutamate amino acid group synthesis Pyrimidine biosynthesis All pathway labels on this image are links, simply click to access the article.

There is still a lot of work to do on Wikipedia's metabolism articles. Visit the Metabolic Pathways task force page to see what needs doing to the wide range of metabolism-related articles, images and templates. In particular the roadmap for article development may be of interest. On the more general front, the Molecular and Cellular Biology Wikiproject may also have projects of interest.
