The following infographic summarizes the difference between glycolipids and phospholipids in tabular form. Glycolipid constituted 90 to 99% of the total extractable lipid based on 14C-acetate incorporation into six marine caulobacter strains. They have glycerol and sphingosine as their backbones, respectively. INTRODUCTION. In other words, there are no additional phosphate groups in glycolipid structure, but there is a phosphate group in phospholipid. Glycolipids and phospholipids are two types of lipid-containing substances we can find in cell membranes. Marrow MR, Singh D, Lu D, Grant CW (1995) Glycosphingolipid fatty acid arrangement in phospholipid bilayer: Cholesterol effects. The predominant phospholipid species in Gram-positive bacteria are phosphatidylglycerol (PG) and cardiolipin (CL) , whose relative composition varies from species to species . Biophys J 68: 179- 186; Kojima N, Hakomori S (1991) Cell adhesion, spreading, and motility of GM3- expressing cells based on glycolipid-glycolipid interaction. The Phospholipids provides the basic structure of cell membrane, whereas glycolipids act as cell-cell recognition and … phospholipids is one type of lipids The lipid is a big group of molecules containing carbon, hydrogen and oxygen. The main difference between phospholipids and sphingolipids is that phospholipids consist of a glycerol backbone whereas sphingolipids consist of a sphingosine backbone. 3. When the phospholipid molecules are joined by other lipids and integral proteins, the surface can function as a cellular membrane. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. Figure 02: Structure of the Cell Membrane.

Side by Side Comparison – Glycolipids vs Phospholipids in Tabular Form See Wiktionary Terms of Use for details. “Glycolipids.” Nature News, Nature Publishing Group, Available here. We can find these components in bio-membrane structures like lysosomal membrane, mitochondrial membrane, endoplasmic reticulum membrane, and Golgi apparatus membrane. The triglyceride is made of a glycerol molecule connected to three fatty acids. The term amphipathic came from Greek amphis, meaning “both” and pathy, from Greek pátheia, meaning “suffering”, “feeling”. Summary. Learn faster with spaced repetition. Glycolipids are used for … glycolipid Glycolipid , any member of a group of fat-soluble substances particularly abundant in tissues of the nervous system of animals. If one of these fatty acids is substituted by a phosphate group, then the whole molecule becomes a phospholipid. When forming the glycolipid, the sugar molecule binds with a free hydroxyl group of the lipid residue in the backbone through the anomeric carbon of the sugar component. Some glycerides contain a carbohydrate moiety attached to the sn- 3 position of the glycerol. As it extends from the phospholipid bilayer into the watery environment which surrounds the cell it plays a crucial role in acting as a recognition site (e.g lysosomes can recognise its organism’s own cells).
