Phospholipid

Fos fo lip id any lipid that contains phosphorus including those with a glycerol backbone phosphoglycerides and plasmalogens or a backbone of sphingosine or a related substance sphingomyelins.

Phospholipid. Phospholipid also called phosphatide any member of a large class of fatlike phosphorus containing substances that play important structural and metabolic roles in living cells the phospholipids with the sphingolipids the glycolipids and the lipoproteins are called complex lipids as distinguished from the simple lipids fats and waxes and from other fat soluble cell components mostly. When many phospholipids line up they form a double layer that is characteristic of all cell membranes. Phospholipid regulatory functions are both direct and indirect through their metabolites. Phospholipid synthesis occurs in the cytosolic side of er membrane that is studded with proteins that act in synthesis gpat and lpaat acyl transferases phosphatase and choline phosphotransferase and allocation flippase and floppase.

They are the major lipids in cell membranes. A phospholipid is composed of two fatty acids a glycerol unit a phosphate group and a polar molecule. It is well established that phospholipids participate in a broad range of cellular events such as apoptosis and regulation of mitochondrial physiology and that phospholipid derived messenger molecules are crucial for the transduction of extracellular. Alkohol yang mengandung nitrogen dan.

Each phospholipid is made up of two fatty acids a phosphate group and a glycerol molecule. Fosfolipid memiliki kerangka gliserol dan 2 gugus asil pada posisi ketiga dari kerangka gliserol di tempati oleh gugus fosfat yang terikat pada amino alkohol. The phospholipid is shaped like a thumbtack with two tails protruding from the head.

Eventually a vesicle will bud off from the er containing phospholipids destined for. Molekul fosfolipid dapat dipandang terdiri dari dua bagian yaitu kepala dan ekor. A phospholipid is a type of lipid molecule that is the main component of the cell membrane lipids are molecules that include fats waxes and some vitamins among others. The polar head region in the phosphate group of the molecule is hydrophillic attracted to water while the fatty acid tail is hydrophobic repelled by water.

The heads are closer to the inner and. The head is the phosphate group and the tails are the two fatty acids.
