Central Carbon Metabolism & Energy Panel



Central Carbon Metabolism & Energy Panel

Central carbon metabolism, also known as the central carbon metabolic network, refers to a series of biochemical pathways that interconnect catabolic and anabolic processes in living cells.

The key central pathways are glycolysis, pentose phosphate cycle and tricarboxylic acid cycle. This metabolic network converts carbon-containing molecules, such as sugars, fatty acids and amino acids into energy as well as precursor molecules necessary for cell growth, proliferation, and survival.
