Taschenbuch. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - Scientific Study from the year 2018 in the subject Chemistry - Organic Chemistry, grade: A, , language: English, abstract: Heterocyclic chemistry is one of the largest branches of chemistry. Well over six million discrete heterocyclic compounds are known, reflecting their central and important role in Science and Technology. The usefulness of heterocycles is due to their combination of compact and robust molecular structures with a high degree of molecular diversity that results in properties, which can be finely adjusted to the needs of sophisticated applications. This is well illustrated by the functions of many naturally occurring heterocycles that are essential components of living cells, including DNA in which specific nitrogen heterocycles are directly responsible for encoding all genetic information. Morphine and quinine, two of the earliest compounds to be used in therapy and in use today, are both heterocyclic natural products. William Perkin's synthesis of the lucrative quinine molecule in 1856 led to the discovery of an important synthetic heterocycle, mauveine, and this laid the foundation of the synthetic dye industry. This in turn gave birth to the modern industry when in 1932 the antibacterial properties of the dye lead to the discovery of heterocyclic sulfapyridines. These antibacterial agents were the first major life saving synthetic drugs and they quickly had a dramatic effect on the quality of life.…

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Chitin and its deacetylated derivative chitosan are natural polymers which are composed of indiscriminately distributed a-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Chitin and chitosan are used in fields of biomedicine, food and agriculture. The success of chitosan in each of these specific applications is directly associated to their physicochemical properties. The aim of this book is to highlight the relationship between the physicochemical properties of the polymers and their behaviour. A purposeful characterization of chitosan concerning some biological properties and a number of specific applications (drug delivery, tissue engineering, wound dressings, wastewater treatment, and agricultural use and chitosan nanoparticles) is given. The molecular mechanism of the biological properties like biocompatibility, biodegradibility, hydrogel, antiinflammatory, and antimicrobial has been updated. These properties can be further enhanced by modifications of chitosan on its primary amino group. The modifications can be done by graft modification, chemical modifications and chitosan blend system. 60 pp. Englisch.…
