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%.

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.

DSPS (Dioctadecanoylphosphatidylserine) is a glycerophospholipid, an important phospholipid membrane component that plays a key role in cell cycle signaling. DSPS can regulate cellular activity and mediate apoptosis. DSPS is widely used as a nutritional supplement.

Pyrimidine (Metadiazine)s are heterocyclic, six-membered, nitrogen-containing carbon ring structures, with uracil, cytosine and thymine being the basal structures of ribose-containing nucleosides (uridine, cytidine, and thymidine respectively), or deoxyribose-containing deoxynucleosides, and their corresponding ribonucleotides or deoxyribonucleotides. Pyrimidines serve essential functions in human metabolism as ribonucleotide bases in RNA (uracil and cytosine), and as deoxyribonucleotide bases in DNA (cytosine and thymine), and are linked by phosphodiester bridges to purine nucleotides in double-stranded DNA, in both the nucleus and the mitochondria. Pyrimidine activated sugars are also involved in polysaccharide and phospholipid synthesis, glucuronidation in detoxification processes, glycosylation of proteins and lipids and in the recently identified novel endothelium-derived vasoactive dinucleotides.

1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) is a phospholipid containing the unsaturated long-chain (18:1) oleic acid inserted at the sn-1 and sn-2 positions.

Phosphatidylserine is a naturally occurring phospholipid that comprises 2-10% of total phospholipids in mammals and is enriched in the central nervous system, particularly the retina. It is anionic and found mainly on the inner leaflet of the cell membrane. It is biosynthesized from phosphatidylcholine or phosphatidylethanolamine by phosphatidyl synthase 1 (PSS1) or PSS2, respectively, in the endoplasmic reticulum and can be reversibly converted back by the same enzymes. It can also be irreversibly converted to phosphatidylethanolamine by phosphatidylserine decarboxylase in the mitochondria. Phosphatidylserine binds to T cell immunoglobulin mucin type 1 (TIM-1) and TIM-4 receptors as well as brain-specific angiogenesis inhibitor 1 (BAI1), leading to anti-inflammatory and anti-atherosclerotic effects. It is also a cofactor involved in the activation of various signaling pathways through activation of protein kinase C, neutral sphingomyelinase, and c-Raf-1 protein kinase among others. Phosphatidylserine is externalized during apoptosis by scramblases in the plasma membrane as a signal for phagocytes to engulf the cell. Phosphatidylserines (bovine) is a mixture of bovine phosphatidylserines containing fatty acids with variable chain lengths at the sn-1 and sn-2 positions.

C16 Sphingomyelin (d18:1 16:0) (N-Palmitoyl-D-sphingomyelin) is a phospholipid analog of phospholipid bilayer membranes, which can be used to study biofilm activity.

The acyl amides are a family of endogenous lipids that act as potent modulators of pain and inflammation. The best characterized members of this family are the arachidonoyl amides, which includes N-arachidonoyl ethanolamide (AEA; anandamide). N-palmitoyl glycine (PalGly) contains an 18-carbon saturated fatty acid that is amide-linked to glycine and is structurally similar to the phospholipid-derived N-acyl ethanolamines. Endogenously produced in rat skin and spinal cord, PalGly is present in 100-fold greater amounts in skin and 3-fold greater in brain compared to AEA. Injection of 0.43 μg PalGly in rat hindpaw inhibits heat-induced firing of nociceptive neurons in rat dorsal horn. PalGly treatment induces transient calcium influx in native dorsal root ganglion (DRG) cells and in the PTX-sensitive, DRG-like cell line F-11 (EC50 = 5.5 μM).

D-Allose (β-D-Allopyranose) is a rare naturally occurring monosaccharide known to exert anti-proliferative effects on cancer cells. The effects of D-Allose on the cellular membranes of hormone-refractory prostate cancer cell line (DU145), hormone-sensitive prostate cancer cell line (LNCaP), and normal prostate epithelial cells (PrEC) were studied at the molecular level by phospholipid profiling using a shotgun lipidomic method.

Phosphorylethanolamine (O-Phosphorylethanolamine) is a phosphomonoester metabolite of the phospholipid metabolism. Phosphorylethanolamine is a precursor of phospholipid synthesis and a product of phospholipid breakdown. Phosphomonoesters are present at much higher levels in the brain than in other organs. In developing the brain, phosphomonoesters are normally elevated during the period of neuritic proliferation. This also coincides with the occurrence of normal programmed cell death and synaptic pruning in developing the brain. These findings are consistent with the role of phosphomonoesters in membrane biosynthesis. Phosphorylethanolamine shows a strong structural similarity to the inhibitory neurotransmitter, GABA, and the GABAB receptor partial agonist, 3-amino-propylphosphonic acid. Phosphorylethanolamine is a phosphomonoester which is decreased in post-mortem Alzheimer's disease (AD) brain.

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.

Phosphorylcholine is widely present in the biological world, which is a phospholipid present in the eukaryotic biofilm, and also in the symbiotic bacteria or pathogens associated with eukaryotes. Phosphorylcholine has immunomodulatory properties and can be used to study atherosclerosis.

Phosphatidylinositol 4,5-bisphosphate (L-alpha-Phosphatidylinositol-4,5-bisphosphate), a critical phospholipid in cell membranes, serves as a substrate for both phospholipase C (PLC) and phosphoinositide 3-kinase (PI3K) and acts as a primary messenger [1] [2] [3].

Cardiolipin (Heart, Bovine) sodium is a phospholipid found in mitochondria and is involved in mitochondrial structure and function.Cardiolipin (Heart, Bovine) sodium is used in the study of neurological, cardiovascular, and metabolic diseases.
