Available in PDF, EPUB and Kindle. Book excerpt: It was probably the French chemist Portes, who first reported in 1880 that the mucin in the vitreous body, which he named hyalomucine, behaved differently from other mucoids in cornea and cartilage. Fifty four years later Karl Meyer isolated a new polysaccharide from the vitreous, which he named hyaluronic acid. Today its official name is hyaluronan, and modern-day research on this polysaccharide continues to grow. Expertly written by leading scientists in the field, this book provides readers with a broad, yet detailed review of the chemistry of hyaluronan, and the role it plays in human biology and pathology. Twenty-seven chapters present a sequence leading from the chemistry and biochemistry of hyaluronan, followed by its role in various pathological conditions, to modified hylauronans as potential therapeutic agents and finally to the functional, structural and biological properties of hyaluronidases. Chemistry and Biology of Hyaluronan covers the many interesting facets of this fascinating molecule, and all chapters are intended to reach the wider research community. - Comprehensive look at the chemistry and biology of hyaluronans - Essential to Chemists, Biochemists and Medical researchers - Broad yet detailed review of this rapidly growing research area

Book excerpt: Hyaluronic acid is an essential part of connective, epithelial and neural tissues, and contributes to cell proliferation and migration. It is used as a stimulating agent for collagen synthesis and is a common ingredient in skin-care products, a multi-billion dollar industry, as it is believed to be a key factor in fighting the aging process. Hyaluronic Acid: Production, Properties, Application in Biology and Medicine consists of six chapters discussing the various issues of hyaluronic acid research. In Chapter 1, a historical analysis recounts the discovery and milestones of the research leading to the practical applications of hyaluronan. Chapter 2 is dedicated to biological role of the hyaluronic acid in nature, in particular in the human body. The chapter starts from the phylogenesis of hyaluronic acid, then describes hyaluronan functions in human ontogenesis and especially the role which hyaluronan plays in extracellular matrix of the different tissues. Chapter 3 describes the methods to manufacture and purify hyaluronic acid, including the analytical means for assessing quality of the finished product. Chapter 4 discusses the structure and rheological properties of hyaluronic acid considering effects on conformation and biological properties related to molecular weight. In Chapter 5, the physical and chemical methods for modifying the structure of hyaluronan are discussed including cross-linking using bi-functional reagents, solid-phase modification and effects of the combined action of high pressures and shift deformation. The final chapter focuses on the products derived from hyaluronic acid, including therapeutics composed of modified hyaluronan conjugated to vitamins, amino acids and oligo-peptides. The biological roles and medical applications of this polysaccharide have been extensively studied and this book provides a wealth of scientific data demonstrating the critical role of hyaluronic acid and its promise as a multifaceted bio-macromolecule. Approaching hyaluronic acid from multiple angles, this book links relationships between its biological functions, structure and physical–chemical properties. It will be an invaluable resource to researchers, both industrial and academic, involved in all aspects of hyaluronan-based technologies.

Book excerpt: "Hyaluronic acid, or hyaluronan, is a water soluble, anionic extracellular matrix glycosaminoglycan polymer with variable molecular weight that determines its physiological role, rheological properties and applications. Since its discovery in the early 1930s, there has been an increased awareness concerning the biology of hyaluronic acid, its signaling pathways and its role in the biomedical and cosmeceutical industry. Being an endogenous molecule, hyaluronic acid is biocompatible, biodegradable, and has strong mucoadhesive, viscoelastic properties. The authors provide chemical modification approaches to hyaluronic acid, as well as address the magnitude of applications of hyaluronic acid-based targeted drug vectors and patents. The closing study discusses glycosaminoglycans, a specialized group of unbranched, anionic disaccharide polymers attached by a covalent linkage to the membrane proteins via sulphate groups in their sugar moieties"--

Download or read book Hyaluronan in Cancer Biology written by Robert Stern and published by Academic Press. This book was released on 2009-03-07 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyaluronan biology is being recognized as an important regulator of cancer progression. Paradoxically, both hyaluronan (HA) and hyaluronidases, the enzymes that eliminate HA, have also been correlated with cancer progression. Hyaluronan, a long-chain polymer of the extracellular matrix, opens up tissue spaces through which cancer cells move and metastasize. It also confers motility upon cells through interactions of cell-surface HA with the cytoskeleton. Embryonic cells in the process of movement and proliferation use the same strategy. It is an example of how cancer cells have commandeered normal cellular processes for their own survival and spread. There are also parallels between cancer and wound healing, cancer occasionally being defined as a wound that does not heal. The growing body of literature regarding this topic has recently progressed from describing the association of hyaluronan and hyaluronidase expression associated with different cancers, to understanding the mechanisms that drive tumor cell activation, proliferation, drug resistance, etc. No one source, however, discusses hyaluronan synthesis and catabolism, as well as the factors that regulate the balance. This book will offer a comprehensive summary and cutting-edge insight into Hyaluronan biology, the role of the HA receptors, the hyaluronidase enzymes that degrade HA, as well as HA synthesis enzymes and their relationship to cancer.

Download or read book Extracellular Sugar Based Biopolymers Matrices written by Ephraim Cohen and published by Springer. This book was released on 2019-07-02 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extracellular matrix (ECM) is an acellular three-dimensional network composed of proteins, glycoproteins, proteoglycans and exopolysaccharides. It primarily serves as a structural component in the tissues and organs of plants and animals, or forms biofilms in which bacterial cells are embedded. ECMs are highly dynamic structures that undergo continuous remodeling, and disruptions are frequently the result of pathological processes associated with severe diseases such as arteriosclerosis, neurodegenerative illness or cancer. In turn, bacterial biofilms are a source of concern for human health, as they are associated with resistance to antibiotics. Although exopolysaccharides are crucial for ECM formation and function, they have received considerably little attention to date. The respective chapters of this book comprehensively address such issues, and provide reviews on the structural, biochemical, molecular and biophysical properties of exopolysaccharides. These components are abundantly produced by virtually all taxa including bacteria, algae, plants, fungi, invertebrates and vertebrates. They include long unbranched homopolymers (cellulose, chitin/chitosan), linear copolymers (alginate, agarose), peptoglycans such as murein, heteropolymers like a variety of glycosaminoglycans (hyaluronan, dermatan, keratin, heparin, Pel), and branched heteropolymers such as pectin and hemicellulose. A separate chapter is dedicated to modern industrial and biomedical applications of exopolysaccharides and polysaccharide-based biocomposites. Their unique chemical, physical and mechanical properties have attracted considerable interest, inspired basic and applied research, and have already been harnessed to form structural biocomposite hybrids for tailor-made applications in regenerative medicine, bioengineering and biosensor design. Given its scope, this book provides a substantial source of basic and applied information for a wide range of scientists, as well as valuable textbook for graduate and advanced undergraduate students.

This book was released on 2015-11-09 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details polysaccharides and other important biomacromolecules covering their source, production, structures, properties, and current and potential application in the fields of biotechnology and medicine. It includes a systematic discussion on the general strategies of isolation, separation and characterization of polysaccharides and proteins. Subsequent chapters are devoted to polysaccharides obtained from various sources, including botanical, algal, animal and microbial. In the area of botanical polysaccharides, separate chapters are devoted to the sources, structure, properties and medical applications of cellulose and its derivatives, starch and its derivatives, pectins, and exudate gums, notably gum arabic. Another chapter discusses the potential of hemicelluloses (xylans and xylan derivatives) as a new source of functional biopolymers for biomedical and industrial applications. The algal polysaccharide, alginate, has significant application in food, pharmaceuticals and the medical field, all of which are reviewed in a separate chapter. Polysaccharides of animal origin are included with separate chapters on the sources, production, biocompatibility, biodegradability and biomedical applications of chitin (chitosan) and hyaluronan. With the increasing knowledge and applications of genetic engineering there is also an introduction in the book to nucleic acid polymers, the genome research and genetic engineering. Proteins and protein conjugates are covered, with one chapter providing a general review of structural glycoproteins, fibronectin and laminin, together with their role in the promotion of cell adhesion in vascular grafts, implants and tissue engineering. Another chapter discusses general aspects of a number of industrial proteins, including casein, caseinates, whey protein, gluten and soy proteins, with emphasis on their medical applications, and with reference to the potential of bacterial proteins. Another natural polymer resource, microbial polyesters, although small compared with polysaccharides and proteins, is also gaining increasing interest in biomedical technology and other industrial sectors. One chapter, therefore, is devoted to microbial polyesters, with comprehensive coverage of their biosynthesis, properties, enzymic degradation and applications. By dealing with biopolymers at the molecular level, the book is aimed at the biomedical and wider materials science communities and provides an advanced overview of biopolymers at the graduate and postgraduate level.
