Metabolische

Metabolische is a term used in Dutch and other European languages to describe things related to metabolism, the set of chemical reactions that sustain life. Metabolism comprises two broad categories: catabolism, which breaks down molecules to release energy, and anabolism, which uses energy to synthesize cellular components such as proteins, lipids, and nucleic acids. Enzymes, cofactors, and regulatory molecules orchestrate these processes, with activity influenced by nutrients, hormones, and the cell’s energy status.

In humans and other organisms, metabolism underpins energy production, growth, and maintenance. Major pathways include glycolysis, the citric acid cycle, and oxidative phosphorylation for carbohydrate and energy metabolism, as well as beta-oxidation of fatty acids and amino acid metabolism. Metabolic regulation involves hormones such as insulin, glucagon, and thyroid hormones, and organisms often exhibit metabolic flexibility to switch between fuel sources like glucose, fats, and ketones in response to availability and need.

Clinical relevance is central to the term, as many diseases arise from metabolic dysfunction. Examples include diabetes mellitus and insulin resistance affecting carbohydrate metabolism; obesity and metabolic syndrome; inherited disorders such as phenylketonuria and galactosemia; and mitochondrial diseases that impair cellular energy production. Diagnostic approaches frequently involve metabolic panels, targeted metabolite measurements, and broader metabolomics to characterize systemic metabolic changes.

Metabolische literature and research focus on understanding these pathways, their regulation, and how alterations contribute to health and disease. The concept spans basic biology, physiology, nutrition, and medicine, reflecting metabolism’s fundamental role in life.
