ABSTRACT Lipid membranes form the essential barriers that compartmentalize life, separating intracellular processes from the external environment. To maintain cellular function and viability, both the plasma membrane and internal organelle membranes undergo continuous compositional and functional remodeling in response to environmental fluctuations. Traditionally, glycerophospholipids have been primarily considered structural components of these membranes. However, their dynamic synthesis plays a crucial role in modulating membrane functions and, consequently, cellular adaptability. This Review discusses how cells orchestrate complex glycerophospholipid metabolism to adapt to diverse environmental challenges. By examining membrane adaptation to various changes, including temperature shifts, pH imbalances and nutrient availability, we propose that responsive alterations in glycerophospholipid synthesis act as a central metabolic hub. This hub influences overall cellular metabolism and regulatory networks. This Review highlights an often overlooked aspect of lipid biology: the pivotal role of glycerophospholipid metabolism in modulating cellular adaptability and resilience.
