Diacylglycerols, sn-1,2-, - structure, occurrence, biochemistry and ...
Diacylglycerols are believed to interact with the insulin signalling cascade and thence of glucose uptake in skeletal muscle. They are one of the precursors of the endocannabinoid 2‑arachidonoylglycerol with its own distinctive signalling properties.
Diacylglycerol: Structure, Functions, and Analytical Methods
Diacylglycerol is a multifaceted lipid molecule that holds paramount significance in cellular physiology. Its diverse roles as a structural component, signaling molecule, and metabolic intermediate make it a key player in maintaining cellular homeostasis and regulating various biological processes.

Diglyceride - Wikipedia
A diglyceride, or diacylglycerol (DAG), is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. [1] Two possible forms exist, 1,2-diacylglycerols and 1,3-diacylglycerols.
Diacylglycerol - an overview | ScienceDirect Topics
Diacylglycerol is a key regulator of cell physiology, controlling the membrane recruitment and activation of signaling molecules. Accordingly, diacylglycerol generation and metabolism are strictly controlled, allowing for localized regulation of its concentration.
Diacylglycerol - an overview | ScienceDirect Topics
Diacylglycerol (DAG) is a lipid present in all eukaryotic cell membranes and has a pivotal role in lipid metabolism and signaling processes that controls several cell function by regulating the localization of protein kinase C (PKC).

2012年12月5日 · The fold topologies of the catalytic domains of three α/β hydrolase lipases—namely (a) the pancreatic lipase, (b) hormone sensitive lipase and (c) DAGL. The fold consists of a core eight β-sheets (shown in dark blue) linked in various ways via α-helices (red), β-sheets (light blue) and loops.
Diacylglycerol, when simplicity becomes complex - Cell Press
Diacylglycerol (DAG) is a simple lipid consisting of a glycerol molecule linked through ester bonds to two fatty acids in positions 1 and 2 (Figure 1). Its small size and simple composition confer exceptional properties on DAG as a lipid intermediate in metabolism, as a component of biological membranes (Box 1), and as a second messenger.
