Diacylglycerols

Meaning

Diacylglycerols (DAGs) are a class of lipids composed of a glycerol backbone esterified to two fatty acid chains, serving as crucial secondary messengers in numerous cellular signaling cascades. These molecules are rapidly produced within the cell membrane in response to external stimuli, acting as key intermediaries in signal transduction. Their concentration and composition are highly regulated, reflecting the cell’s metabolic state and responsiveness to various growth factors and hormones. DAGs are fundamentally involved in processes like cell growth, differentiation, and inflammation.
