Platelet metabolism

Platelet metabolism refers to the integrated biochemical pathways, primarily glycolysis and oxidative phosphorylation, that generate the energy required for platelet activation and hemostasis (Arakelyan et al., 2021). Although platelets are anucleate, they possess functional mitochondria and a robust glycolytic capacity, allowing them to rapidly increase energy production upon stimulation (Kramer et al., 2014). In metabolic disorders such as diabetes, platelets often exhibit metabolic dysfunction, which significantly increases the risk of arterial thrombosis (Zaccardi et al., 2015). While platelet metabolism is a broad biological process rather than a single molecular target, specific components such as cyclooxygenase-1 (COX-1) or mitochondrial complexes are targeted by pharmacological agents to modulate thrombotic potential (Ravi et al., 2015). Current antiplatelet therapies, including aspirin and P2Y12 inhibitors, indirectly affect metabolic demand by inhibiting activation pathways (Melchinger et al., 2019). Consequently, this entry is classified as incorrect as a target because it represents a complex physiological process involving numerous enzymes and transporters rather than a single druggable molecule.
