palmitoyl thio-pc

Thioester analogs of glycerophospholipids, in combination with Ellman's reagent, are convenient colorimetric substrates for the measurement of phospholipase (PL) activity. Palmitoyl thio-PC is a chromogenic PLA2 substrate that contains a palmitoyl thioester at the sn-2 position of the glycerol backbone. Hydrolysis of the thioester by PLA2 yields a free thiol that reacts readily with DTNB (Ellman's reagent) giving a bright yellow product with an absorbance maximum at 412 nm. Palmitoyl thio-PC has been used to measure bee venom sPLA2 activity in a phospholipid:Triton X-100 mixed micelle system.

1-Palmitoyl-2-oleoyl-sn-glycero-3-PC (Palmitoyloleoylphosphatidylcholine) is a phospholipid commonly found in cell membranes, with cholesterol compositions ranging from 0 to 60 mol%.

1-Palmitoyl-2-Linoleoyl-sn-glycero-3-phosphatidylcholine (PC) is a phospholipid characterized by the incorporation of palmitic (16:0) and linoleic (18:2) acids at the sn-1 and sn-2 positions, respectively. It is utilized in the creation of micelles, liposomes, and various artificial membranes, playing a significant role in research on lipid peroxidation.

Arachidonoyl Thio-PC is a substrate for various phospholipase A2s (PLA2s), including sPLA2, cPLA2, and iPLA2. Cleavage of the sn-2 fatty acid by PLA2 produces a free thiol that reacts with chromogenic reagents like DTNB (Ellman's reagent) and DTP, facilitating PLA2 activity quantitation. Isozyme-specific cPLA2 activity can be measured by excluding or inhibiting sPLA2 and iPLA2 activities in the assay.

1-Palmitoyl-2-lauroyl-sn-glycero-3-PC (1,2-PLPC) is a phospholipid with palmitoyl (16:0) and lauryl (12:0) acyl chains at the sn-1 and sn-2 positions, respectively. This mixed-chain phosphatidylcholine aids in researching the role of chain-chain contact interactions in maintaining the structural stability of lipid membrane bilayers.

1-Oleoyl-2-palmitoyl-sn-glycero-3-phosphatidylcholine (PC), derived from oleic acid, is used in liposome synthesis [1].

1-Palmitoyl-2-arachidonoyl-sn-glycero-3-PC (PAPC) is a phospholipid found in biological membranes, featuring palmitic acid (16:0) and arachidonic acid (20:4) at the sn-1 and sn-2 positions, respectively. PAPC undergoes oxidation in vivo, producing derivatives that play roles in chronic inflammation and vascular disease. Additionally, PAPC has been utilized in the investigation of oxidized phospholipid signaling mechanisms. Notably, PAPC levels are diminished in isolated human multiple myeloma cells.

1-Palmitoyl-2-13(S)-HpODE-sn-glycero-3-PC is a phospholipid featuring palmitic acid at the sn-1 position and 13(S)-HpODE at the sn-2 position.

1-1(Z)-Hexadecenyl-2-palmitoyl-sn-glycero-3-PC, a plasmalogen, appears in various rat tissues including the liver, heart, kidney, and both gluteus and soleus muscles, as well as visceral and subcutaneous adipose tissues. It serves in lipid bilayer synthesis to investigate how amphiphilic compounds, like lysophosphatidylcholine (1-palmitoyl-2-hydroxy-sn-glycero-3-PC) and lysoplasmenylcholine, influence membrane dynamics.
