A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...

While single reactions and metabolic pathways have been studied in detail, it has been painstaking to determine which are active or "carry flux" in a given cell at a given moment. The first paper ...

Metabolism refers to all of the chemical reactions that take place inside living cells. Unicellular and multicellular organisms must control their metabolism in order to survive. Metabolic rates ...

The most comprehensive model of the brain’s metabolism, incorporating more than 16,800 biochemical interactions, has ...

Researchers at University of California, Los Angeles (UCLA) have developed a tiny sensor that can help keep tabs on ...

The chart of life's metabolic reactions connects substrates, products, and enzymes in a maze of bewildering complexity (Figure 1). To understand how an organism's metabolism determines its ...

What Are Inherited Metabolic Disorders? Inherited metabolic disorders are genetic conditions that result in metabolism problems. Most people with inherited metabolic disorders have a defective ...

Model allowed researchers to better understand the complex molecular mechanisms that determine the robustness, flexibility, and adaptability of the aging brain.

All cells produce substances that are essential for them to function properly. For example, in plants, specific metabolic pathways can produce glucose and chlorophyll. Metabolic pathways can be ...
