sn-glycerol

1,2-Distearoyl-sn-glycerol is an internal standard for the isolation and characterization of molecular species of 1,2-diacyl-sn-glycerol (DAG).

sn-Glycerol 3-phosphate, produced by the reduction of dihydroxyacetone phosphate by NADH formed during glycolysis of the cytoplasmic glycerol 3-phosphate dehydrogenase pathway.

1,2-Dipalmitoyl-sn-glycerol 3-phosphate sodium, a phosphatidic acid, is an endogenous human metabolite.

1-Stearoyl-2-arachidonoyl-sn-glycerol (DAG) is a diacylglycerol (DAG) substrate that can be hydrolyzed to 2-arachidonic acid glycerol. 1-Stearoyl-2-arachidonoyl-sn-glycerol activates PKC, induces Ca2+ influx, and can induce tracheal smooth muscle contraction.

1,2-Dipalmitoyl-sn-glycerol ((S)-1,2-Dipalmitin) is an analog of the PKC-activating second messenger diacylglycerol (DAG). It weakly activates PKC.

1-Stearoyl-rac-glycerol is a monoacylglycerol that contains stearic acid at the sn-1 position. 1-Stearoyl-rac-glycerol levels are decreased in tumor tissue in a mouse model of azoxymethane-induced colorectal carcinogenesis. 1-Stearoyl-rac-glycerol has been used in the composition of transfersomes for transdermal delivery of doxorubicin in rats, leading to doxorubicin accumulation in lymph nodes, spleen, and heart.

Glycerophospholipids, cephalins (Phosphatidylethanolamines (egg)) are a mixture of phosphatidylethanolamines isolated from eggs, with various fatty acyl groups at the sn-1 and sn-2 positions. Glycerophospholipids and cephalins can be completely hydrolyzed to obtain 1 mol of glycerol, phosphoric acid, ethanolamine and 2 mol of fatty acids. Phosphatidylethanolamines play a role in membrane fusion and disassembly of contractile rings during cell division, regulating membrane curvature. Phosphatidylethanolamines are able to transmit infectious prions without the help of any proteins or nucleic acids. One of the main roles of Phosphatidylethanolamines in bacterial membranes is to disperse the negative charges caused by anionic membrane phospholipids.

1,3-Dilinoleoyl-2-oleoyl-rac-glycerol is a triacylglycerol that contains linoleic acid at the sn-1 and sn-3 positions and oleic acid at the sn-2 position. It has been found in grape seed, pumpkin seed, soybean, sunflower, and wheat germ oils, with the highest content in grape seed oil.

1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE), a phospholipid member of the glycerophosphonoethanolamine family, is a major component in biological membranes. Studies have shown that cholesterol induces condensation of DPPE monolayers in the presence of Ca2+ ions, leading to more ordered lipid tails and resulting in a thicker membrane.
