Nutrient metabolism

Nutrient metabolism is the integrated network of biochemical reactions that convert macronutrients—carbohydrates, proteins, and fats—into energy (ATP) and essential molecular building blocks. This process is divided into catabolism, the breakdown of molecules to obtain energy, and anabolism, the synthesis of all compounds needed by the cells. It is not a single molecular target but a broad biological category encompassing thousands of specific enzymes, transporters, and signaling proteins like mTOR and AMPK (StatPearls, 2023). Dysregulation of nutrient metabolism is central to the pathogenesis of metabolic syndrome, type 2 diabetes, and cardiovascular diseases (NIH, 2022). Therapeutic strategies often focus on specific nodes within these pathways to restore metabolic balance, such as using statins to inhibit cholesterol synthesis or GLP-1 agonists to enhance glucose-dependent insulin secretion (PubMed, 2021). Understanding the systemic nature of nutrient metabolism is critical for drug development to avoid unintended disruption of global energy homeostasis.

Drugs modulate nutrient metabolism by targeting specific enzymes (e.g., HMG-CoA reductase), receptors (e.g., PPAR-gamma), or transporters (e.g., SGLT2) to alter the flux of metabolites through biochemical pathways.
