Introduction

Metabolism constitutes the intricate web of biochemical reactions that sustain life within every cell of the human body. From generating energy to synthesizing biomolecules and regulating signaling pathways, metabolic processes are fundamental to cellular function and organismal health. The comprehensive mapping of human metabolic pathways has emerged as a transformative endeavor in biomedical research, offering profound insights into physiological processes and disease mechanisms [1,2]. Human metabolism is a dynamic and interconnected network involving thousands of metabolites and enzymes. These pathways not only provide the building blocks necessary for cellular structure and function but also serve as key regulators of biochemical homeostasis. Understanding the intricacies of these metabolic networks is crucial for elucidating how cells respond to internal and external stimuli, adapt to varying nutritional states, and maintain cellular integrity. Advancements in technology, particularly in metabolomics, proteomics, and computational modeling, have revolutionized our ability to map and analyze human metabolic pathways with unprecedented detail [3,4]. These interdisciplinary approaches enable the systematic exploration of metabolic fluxes, pathway interactions, and regulatory mechanisms across different tissues and disease states. By integrating large-scale data sets, researchers can reconstruct metabolic networks and identify critical nodes that govern metabolic homeostasis. Moreover, the implications of metabolic pathway mapping extend beyond fundamental biology to clinical applications [5-7]. Dysregulation of metabolic pathways is intricately linked to the pathogenesis of numerous diseases, including metabolic disorders, cancer, cardiovascular diseases, and neurodegenerative conditions. Mapping these pathways not only aids in identifying biomarkers for disease diagnosis and prognosis but also facilitates the development of targeted therapies aimed at restoring metabolic balance and improving patient outcomes. In this review, we explore recent advancements in the mapping of human metabolic pathways, emphasizing its significance in unraveling cellular function and disease mechanisms [8]. By integrating insights from basic research and clinical studies, we highlight the transformative potential of metabolic pathway mapping in advancing personalized medicine and improving public health outcomes.
