metabolismia

Metabolismia is an interdisciplinary concept that seeks to understand the regulation, integration, and dynamics of metabolism across biological systems. It encompasses the chemical reactions that convert nutrients into energy and building blocks, as well as the control mechanisms that coordinate these reactions in time and space.

Core topics include metabolic pathways, energy balance, redox state, and carbon/nitrogen flux. Metabolomics, flux analysis, isotope tracing, and computational modeling (including constraint-based models and dynamic simulations) are used to map and quantify metabolism. Regulation by enzymes, transcriptional control, signaling networks, and circadian rhythms are considered.

Applications span medicine, biotechnology, agriculture, and ecology. In medicine, metabolismia informs understanding of metabolic diseases, cancer metabolism, and aging. In biotechnology, it supports metabolic engineering and synthetic biology to optimize production. In ecology, it helps explain how organisms adapt to nutrient availability.

Although not universally standardized, the term metabolismia has appeared in theoretical discussions and educational materials as an umbrella for system-level metabolic study. It draws on metabolomics, systems biology, and physiology. Critics note the need for clear definitions to avoid overlap with existing fields such as metabolism, bioenergetics, and systems biology.
