Difference Between Phospholipids and Sphingolipids

The main difference between phospholipids and sphingolipids is that phospholipids consist of a glycerol backbone whereas sphingolipids consist of a sphingosine backbone. ... Phospholipids and sphingolipids are two classes of lipids mainly found in the cell membrane of all living organisms.

Is a sphingolipid a phospholipid?

Sphingolipids refer to a class of complex phospholipids with a core hydrophobic structure of ceremide, which is composed of a sphingosine head and a long-chain fatty acid chain. They are essential components of plasma membranes.

What are glycolipids phospholipids and sphingolipids?

Phospholipids are lipids containing phosphorus. Glycolipids are sugar-containing lipids. ... Sphingolipids are phospholipids or glycolipids that contain the unsaturated amino alcohol sphingosine rather than glycerol.

What is the function of sphingolipids?

FUNCTIONS OF SPHINGOLIPIDS

Sphingolipids are both structural and functional lipids. Their physical properties (such as high phase transition temperatures) affect the properties of membranes and lipoproteins, and they are critical components of the water barrier of skin.

What is difference between sphingolipid and sphingomyelin?

Sphingomyelin (SPH, ˌsfɪŋɡoˈmaɪəlɪn) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath that surrounds some nerve cell axons. ... In humans, SPH represents ~85% of all sphingolipids, and typically make up 10–20 mol % of plasma membrane lipids.

What foods contain phospholipids?

Phospholipids are found in foods like meat, eggs, seed oils, and seafood. They're also found in some plant foods but in much smaller amounts. Phospholipids can also be found in supplements. Marine phospholipids are derived from fish, algae, and shellfish like krill.

Which is not a phospholipid?

Gangliosides is not a phospholipid.

What are the two major kinds of phospholipids?

Phosphatidylcholine and phosphatidylserine are examples of two important phospholipids that are found in plasma membranes. Phospholipid MoleculeA phospholipid is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone.

What are two major types of sphingolipids?

Definition: Sphingolipids are a class of lipids derived from the aliphatic amino alcohol sphingosine. There are three main types of sphingolipids: ceramides, phosphosphingolipids (sphingomyelins), and glycosphingolipids, which differ in the substituents on their head group.

What is the main function of a glycolipid?

Glycolipids are glycoconjugates of lipids that are generally found on the extracellular face of eukaryotic cellular membranes, and function to maintain stability of the membrane and to facilitate cell–cell interactions. Glycolipids can also act as receptors for viruses and other pathogens to enter cells.

What do sphingolipids contain?

Sphingosine is one of more than 60 long-chain amino alcohols found in animals, plants, and microorganisms. The bases commonly contain between 12 and 22 carbon atoms in the chain. A ceramide, which is an amide formed from a fatty acid and sphingosine, is the characteristic parent structure of all sphingolipids.

What do all sphingolipids have in common?

4 Sphingolipids. SPs can be divided into several major classes, all sharing a common structural feature: a sphingoid base backbone that is synthesized de novo from serine and a long-chain fatty acyl-CoA, and then converted into species of different complexities.

What are sphingolipids composed of?

The sphingolipids, like the phospholipids, are composed of a polar head group and 2 nonpolar tails. The core of a sphingolipid is the long-chain amino alcohol, sphingosine (Figure 21-1). The sphingolipids include the sphingomyelins and glycosphingolipids (the cerebrosides, sulfatides, globosides, and gangliosides).
