  2. Phosphatidylserine - Wikipedia

    en.wikipedia.org/wiki/Phosphatidylserine

    Phosphatidylserine (abbreviated Ptd-L-Ser or PS) is a phospholipid and is a component of the cell membrane. [1] It plays a key role in cell cycle signaling, specifically in relation to apoptosis . It is a key pathway for viruses to enter cells via apoptotic mimicry . [ 2 ]

  3. Phospholipid - Wikipedia

    en.wikipedia.org/wiki/Phospholipid

    Phospholipid synthesis occurs in the cytosolic side of ER membrane [15] that is studded with proteins that act in synthesis (GPAT and LPAAT acyl transferases, phosphatase and choline phosphotransferase) and allocation (flippase and floppase). Eventually a vesicle will bud off from the ER containing phospholipids destined for the cytoplasmic ...

  5. Glycerophospholipid - Wikipedia

    en.wikipedia.org/wiki/Glycerophospholipid

    Cells will use this phosphatidylserine to enter cells via apoptotic mimicry. The structure of this lipid differs in plants and animals, regarding fatty acid composition. In addition, phosphatidylserine plays an important role in the human brain content, as it makes up 13–15% of the phospholipids in the human cerebral cortex.

  6. Phosphatidylethanolamine - Wikipedia

    en.wikipedia.org/wiki/Phosphatidylethanolamine

    Phosphatidylserine decarboxylase is the enzyme that is used to decarboxylate phosphatidylserine in the first pathway. The phosphatidylserine decarboxylation pathway is the main source of synthesis for phosphatidylethanolamine in the membranes of the mitochondria. Phosphatidylethanolamine produced in the mitochondrial membrane is also ...

  7. Phosphatidic acid - Wikipedia

    en.wikipedia.org/wiki/Phosphatidic_acid

    Besides de novo synthesis, PA can be formed in three ways: By phospholipase D (PLD), via the hydrolysis of the P-O bond of phosphatidylcholine (PC) to produce PA and choline. [4] By the phosphorylation of diacylglycerol (DAG) by DAG kinase (DAGK). By the acylation of lysophosphatidic acid by lysoPA-acyltransferase (LPAAT); this is the most ...

  8. Phosphatidylinositol - Wikipedia

    en.wikipedia.org/wiki/Phosphatidylinositol

    The synthesis of Phosphatidylinositol (PI) is limited to the Endoplasmatic Reticulum (ER), which is the largest membrane component of the cell. [23] This site also contributes the synthesis to the majority of phospholipids, namely phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylserine (PS) and triacylglycerol (TG). [24]

  9. Lipid - Wikipedia

    en.wikipedia.org/wiki/Lipid

    Phosphatidylserine lipids are known to be involved in signaling for the phagocytosis of apoptotic cells or pieces of cells. They accomplish this by being exposed to the extracellular face of the cell membrane after the inactivation of flippases which place them exclusively on the cytosolic side and the activation of scramblases, which scramble ...
