The Zephyris/Sandbox2 Portal 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.

Selected article No article is currently set as 'article of the month' for April Did you know... ...that human metabolism cannot synthesise 8 to 10 (depending on age) of the 20 standard amino acids? ...that the sugar ribose is vital for all life as it is used in the synthesis of DNA, RNA and ATP? ...that nitrogen can only be fixed metabolically by a group of prokaryotes known as diazotrophs? ...that in humans the balance between anabolism and catabolism of glucose is largely regulated by insulin? ...that hydrogen can be biologicaly produced by some algae with the enzyme hydrogenase?

Things you can do There is still a lot of work to do on Wikipedia's metabolism articles. Visit the Metabolic Pathway Wikiproject 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.
