8. Schnaar RL (2004) Glycolipid-mediated cell-cell recognition in inflammation and nerve regeneration. Glycolipid: Types and Functions The term "glycolipid" defines the combined lipids of the glycerol moiety and these fatty acid chains. Glycolipid-based antigens are easily recognized by antibodies, which attack any foreign substances they find. Glyco meaning one or many monosaccharide particle or compound that is attached with a glycosidic linkage. The cell membrane is usually composed of phospholipid bilayers. [7], An example of how glycolipids function within the body is the interaction between leukocytes and endothelial cells during inflammation. The backbone of glycolipids is made with glycerol. Intracellular ceramide stimulated DNA synthesis in endothelial smooth muscle cells and also induced mitogenesis by platelet-derived growth factor [15]. providing energy when other fuels are depleted. These lipids combine glucose or galactose with the hydroxyl group of glycerols alpha position. Rafts are found within the cell membrane and provide regions which contain receptors and signaling molecules on the surface of the cell. Glycolipids are the hybrid molecules constructing with hydrophilic carbohydrate and hydrophobic chains, and show the unique physicochemical properties and bioactivities. This lipid is located in the outer membrane of the cell. [9], Blood types are an example of how glycolipids on cell membranes mediate cell interactions with the surrounding environment. - Types, Symptoms & Treatment, Sepsis Infection: Definition, Symptoms & Criteria, Surgical Asepsis: Definition, Technique & Examples, Ascaris Lumbricoides: Symptoms & Treatment, Definitive & Intermediate Hosts in Parasitic Life Cycles, Microbiology Laboratory Techniques: Help and Review, Microorganisms and the Environment: Help and Review, Gastrointestinal Tract Illnesses & Infections: Help & Review, Sexually Transmitted Bacterial Diseases: Help and Review, Bloodborne Bacterial Diseases: Help and Review, Bacterial Diseases of the Respiratory Tract: Help and Review, Bacterial Skin and Wound Infections: Help and Review, Immunology And the Body's Defenses Against Pathogens: Help and Review, Food and Industrial Microbiology: Help and Review, Sterilization and Antiseptic Techniques: Help and Review, 6th Grade Life Science: Enrichment Program, 7th Grade Life Science: Enrichment Program, 8th Grade Life Science: Enrichment Program, Middle School Physical Science Curriculum Resource & Lesson Plans, 7th Grade Physical Science: Enrichment Program, ILTS Science - Physics (116): Test Practice and Study Guide, What is Basal Body Temperature? This integration results in increased cell response and cell recognition. Biophys J 68: 179- 186. Although they account for as much as 60% of all membrane lipids in animals and plants, their functions remain poorly understood. Edidin M (2003). The four main human blood types (A, B, AB, O) are determined by the oligosaccharide attached to a specific glycolipid on the surface of red blood cells, which acts as an antigen. Its main function is to serve as antigens. These lipids extend from the phospholipid bilayers into the extracellular part. Glycolipids are also important for cell recognition and connecting cells to form tissues. Similar glycoprotein and glycolipid types are on the surfaces of viruses and may change frequently, preventing immune cells from recognizing and attacking them. 4. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. It plays a special role in the process of photosynthesis. Sphingolipidoses are typically inherited, and their effects depend on which enzyme is affected, and the degree of impairment. They help to determine the types of blood groups, which are used in allowing cells to recognize each other. It also serves as a cell marker. Jordan S, Rodgers W (2003) T-cell glycolipid-enriched membrane domains are constitutively assembled as membrane phases that translocate to immune synapses. 13. I am an active member of the Indian association of applied microbiology (IAAM). They may be as complicated a set of compounds as the negatively charged gangliosides in animals. Further elongation can occur via glycosyltransferases and sulfotransferases. Your Mobile number and Email id will not be published. Structure and Synthesis The basic structure of a glycolipid consists of a mono- or oligosaccharide group attached to a sphingolipid or a glycerol group (can be acetylated or alkylated) with one or two fatty acids.
