Plasmalogens:

 There are two sorts of ether phospholipids, plasmanyl-and plasmenyl-phospholipids. Plasmanyl-phospholipids have an ether bond in position sn-1 to an alkyl gathering. Plasmenyl-phospholipids have an ether bond in position sn-1 to an alkenyl gathering. The last are called plasmalogens. In warm blooded creatures, the sn-1 position is ordinarily gotten from C16:0, C18:0, or C18:1 greasy alcohols while the sn-2 position is most generally involved by polyunsaturated unsaturated fats (PUFAs). The most widely recognized head bunches present in mammalian plasmalogens are ethanolamine (assigned plasmenylethalomines) or choline (assigned plasmenylcholines). Capacities: Plasmalogens are found in various human tissues, with specific improvement in the apprehensive, insusceptible, and cardiovascular framework. In human heart tissue, almost 30–40% of choline glycerophospholipids are plasmalogens. Considerably all the more striking is the way that 32% of the glycerol phospholipids in the grown-up human heart and 20% in cerebrum and up to 70% of myelin sheath ethanolamine glycerol phospholipids are plasmalogens. In spite of the fact that the elements of plasmalogens have not yet been completely explained, it has been shown that they can secure mammalian cells against the harming impacts of receptive oxygen species. Likewise, they have been ensnared as being flagging atoms and modulators of film elements. Plasmalogens were first depicted by Feulgen and Voit in 1924 dependent on investigations of tissue areas. They rewarded these tissue areas with corrosive or mercuric chloride as a major aspect of a technique to recolor the core. This brought about the breakage of the plasmalogen vinyl-ether cling to yield aldehydes. Thus, the last responded with a fuchsine-sulfurous corrosive stain utilized in this atomic recoloring technique and offered ascend to hued mixes inside the cytoplasm of the phones. Plasmalogens were named dependent on the way that these shaded mixes were available in the "plasmal" or within the cell.
