Phospholipids are found in a limited number of foods. They consists of a glycerol backbone with two fatty acids and a compound that contains phosphate. Why are they important in food and in the body?.



Answer :

Esters of glycerol, fatty acids, phosphoric acid, and other alcohols make up phospholipids.Phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylserine are the four most prevalent phospholipids.

Where are phospholipids found in food?

  • The plasma membrane, the top layer of animal cells, is largely made up of phospholipids.They are made up of fatty acid chains joined to a glycerol backbone, just like fats.Phospholipids have two fatty acids that contribute to the formation of a diacylglycerol, as opposed to triglycerides, which have three fatty acids
  • Phospholipids are amphiphilic lipids consisting of a glycerol backbone or an amino-alcohol sphingosine backbone, which is esterified to one or two fatty acids, a phosphate group and a hydrophilic residue.
  • Good sources of phospholipids include eggs, organ meats, lean meats, fish, shellfish, cereal grains, and oilseeds, particularly the choline phosphatides phosphatidylcholine, sphingomyelin, and lysophosphatidylcholine.
  • Glycerophospholipids and sphingolipids are two kinds of lipids that make up the significant class of membrane lipids known as phospholipids.
  • The cell membrane is composed of phospholipids, which are created when glycerol interacts with two fatty acids and a phosphate group.
  • One phosphorus atom and four oxygen atoms combine to generate the complex ions known as phosphotes.Another form of lipid that does not contain glycerol is steroids.
  • A phospholipid is a molecule made composed of a glycerol backbone, two fatty acids, and a modified phosphate group.The phosphate can change by having polar or charged chemical groups added to it.
  • These hydrophilic and hydrophobic characteristics of phospholipids lead them to group into two layers when cellular membranes are formed.
  • Because they are hydrophobic, the phosphate tails in between the layers of heads avoid contact with the water while the heads in each layer face the aqueous or watery environment on either side.
  • The vital phospholipid fatty acids (PLFA), which degrade quickly after cell death and act as a marker to distinguish between living and dead organisms, are part of the cell membrane of microorganisms.
