(n.) A dagger; a poniard.
(n.) A large pistol formerly used.
(n.) The unbranched antler of a young deer.
(n.) A misty shower; dew.
(n.) A loose end; a dangling shred.

(v. i.) To be misty; to drizzle.
Example Sentences:
(1) In general, optimal DAGAT activity in vitro was observed when long-chain unsaturated acyl-CoAs and diacylglycerols (DAGs) containing long acyl chains were used as substrates for in vitro TAG synthesis (although 1,2-didecanoin was also very effective).

High glucose did not stimulate phosphoinositide hydrolysis, as evidenced by the absence of an increase in the water-soluble inositol phosphates, indicating that DAG was not generated through the action of a phosphoinositide-specific phospholipase C. Cells treated with the cell-permeable DAG analogue 1-oleoyl-2-acetyl glycerol to activate PKC displayed approximately two-fold increases of fibronectin, laminin, and type IV collagen mRNA levels after normalization against actin.

(10) In order to characterize the properties of the glyceroglycolipid membranes, ESR spectroscopic studies were carried out with an acyl spin-labeled galactosyl ceramide (SL-GC) or a headgroup spin-labeled phospholipid (SL-6-DPPA) in 1,2-dipalmitoyl[beta-cellobiosyl-(1'---3)]glycerol (Cel-DAG) liposomal membranes.
