Assistant Professor (Pharmaceutics) Heparan/heparin sulfate and chondroitin sulfate are the most common GAGs contained by proteoglycans. Tunicamycin. The majority of the GAG chains are chondroitin/dermatan sulfate with the remainder being keratan sulfate. Clipping is a handy way to collect important slides you want to go back to later. Connective tissue (Figure 39-1) refers to the matrix composed of the ECM, cells (primarily fibroblasts), and ground substance that is tasked with holding other tissues and cells together forming the organs. Ground substance is a complex mixture of GAGs, proteoglycans, and glycoproteins (primarily laminin and fibronectin), but generally does not include the collagens. • Proteoglycans typically contain more glycan than protein. Protein domains that have a necessary function are often used in many different proteins. Proteoglycans (PGs) are composed of a core protein with long chains of sugars covalently attached. N-linked Glycoproteins These types of glycoproteins are modified and synthesized inside the membrane organelles of a cell. Presentation Title: Glycoproteins And Proteoglycans . Proteoglycans are complex extracellular macromolecules consisting of a multidomain core protein to which is attached one or more glycosaminoglycan (GAG) chains. Clipping is a handy way to collect important slides you want to go back to later. fibronectin, laminin and tenascin). Share it! The liver is the main site of transferrin synthesis but other tissues and organs, including the brain, also produce transferrin. Glycoproteins change the plasma membrane permeability making it easier for the attraction of eggs to the sperm cells. The various proteoglycans have been divided into several major classes which are defined by their function, tissue distribution, and protein homologies.

Proteoglycans are one of the major components of the extracellular matrix; they act as fillers between the spaces that occur between cells. The carbohydrate is attached to the protein in a cotranslational or posttranslational modification.This process is known as glycosylation. The glycosaminoglycan chains are much larger than these other types of glycans (e.g., a 20-kD glycosaminoglycan chain contains ~80 sugar residues, whereas a typical biantennary N-glycan contains 10–12 residues). No public clipboards found for this slide. A: Proteoglycans contain a core of protein (vertical rod in drawing) to which molecules of glycosaminoglycans (GAGs) are covalently bound.

The acidic sugar alternates with an amino sugar in repeated disaccharide units. Many forms of proteoglycans are present in virtually all extracellular matrices of connective tissues. Most proteoglycans also contain O- and N-glycans typically found on glycoproteins (see Chapters 8 and 9). Conjugated protein-carbohydrate compounds including mucins, mucoid, and amyloid glycoproteins. N-linked glycoproteins have a carbohydrate bonded to the nitrogen (N) of the amino group (-NH 2) of the R group of the amino acid asparagine.
