Brain phospholipid synthesis

Brain phospholipid synthesis is the metabolic process responsible for creating the structural lipids, such as phosphatidylcholine and phosphatidylethanolamine, that constitute neuronal membranes and synapses. This process occurs primarily via the Kennedy pathway, where rate-limiting precursors including uridine, choline, and omega-3 fatty acids (specifically DHA) are sequentially phosphorylated and activated to form membrane components [1]. In neurodegenerative conditions like Alzheimer's disease, there is a characteristic reduction in brain phospholipid levels and a loss of synaptic connections, which are closely linked to cognitive impairment [2]. Therapeutic approaches involve the administration of multi-nutrient combinations (e.g., Souvenaid) or individual precursors like citicoline to enhance the rate of phospholipid production and support synaptogenesis [3]. Although it is a vital therapeutic objective in neurology, 'Brain phospholipid synthesis' represents a multi-enzyme biochemical pathway rather than a single druggable molecular target such as a receptor or individual enzyme [4].
