DAG tales: the multiple faces of diacylglycerol—stereochemistry, metabolism, and signaling
Cellular and Molecular Life Sciences, 2015 The neutral lipids diacylglycerols (DAGs) are involved in a plethora of metabolic pathways. They function as components of cellular membranes, as building blocks for glycero(phospho)lipids, and as lipid second messengers.
