The Metabolism 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.

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.
