Metabolism is a term that describes the set of life-sustaining chemical reactions in organisms. It can be divided into two categories: catabolism, the breakdown of molecules, and anabolism, the synthesis of molecules. Metabolism is tightly linked to the availability of nutrients such as proteins, lipids and carbohydrates.
Metabolic pathways are a series of chemical reactions of metabolism, which are catalyzed by a sequence of enzymes. However, metabolic signaling pathways refer to the cellular signaling transductions that respond to metabolic state and regulate cellular events to maintain cell and organismal homeostasis. Dysregulation of these pathways is associated width metabolic diseases such as obesity, type 2 diabetes, as well as cancer and aging.
