1. A lipid molecule consisting of glycerol bonded to two fatty acid chains; an intermediate product in fat metabolism and a component of cell membranes.
Usage: biochemistry; also called diacylglycerol (DAG)

Examples

• Diglycerides are produced when triglycerides are broken down during digestion.
• The cell membrane contains phospholipids, which are diglycerides with a phosphate group attached.
• Diglyceride serves as a signaling molecule in cellular processes.
• During fat metabolism, triglycerides are converted to diglycerides and fatty acids.
• Diglycerides play an important role in the synthesis of more complex lipids.
