Download or read book The Complete Book on Water Soluble Gums and Resins written by H. Panda and published by ASIA PACIFIC BUSINESS PRESS Inc.. This book was released on 2011-10-03 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resins, gums and latex are almost ubiquitous in the plant kingdom and many of them continue to play an important role in our daily lives. Numerous plants produce some kind of resin, latex or gum, but only a few are commercially important today, even though their uses and applications are truly manifold. They have been used as adhesives, emulsifiers, thickening agents, they are added to varnishes, paints and ink; they lend their aromas to perfumes and cosmetics and even play a role in pharmacy and medicine. Gums are viscous substances which are secreted by the bark of certain trees. Usually transparent (but sometimes slightly tinted) they contain a mucilage which when dissolved in water makes the latter become viscous. When this mucilage is dissolved in water it can be made to precipitate with alcohol. Resins, on the other hand, are gluey and viscous substances which may be whitish, brownish, or red and are secreted by certain trees when they are incised. Resins contain an essence and are usually not water soluble. Most commonly found types of plant exudates are chemically completely different to gums. Several acacia species are important economically. True gums are complex organic substances mostly obtained from plants, some of which are soluble in water and others of which, although insoluble in water, swell up by absorbing large quantities of it. They are used in adhesives, pharmaceuticals, inks, confections, and other products. Resins are terpene based compounds. Terpenes constitute one of the largest groups of plant chemicals and they can be very complex. They are not water soluble, but can be either oil soluble or spirit soluble, depending on their specific chemical composition. Worldwide interest and activity in gums and resins has grown dramatically in the last few years. Governments, environmentalists, research institutions and other interest groups are among those who have begun to push for stronger support for gums and resins as a way to meet a range of economic, social and environmental goals. Some of the fundamentals of the book are photosynthesis and metabolism of carbohydrates, occurrence, properties and synthesis of the monosaccharides, nitrogen derivatives, carbohydrates in parenteral nutrition, essential carbohydrates, ethers, anhydro sugars and unsaturated derivatives, constitution of nicotinic acid and of nicotinamide, industrial methods of preparing nicotinic acid and nicotinamide, general physiology, metabolism and mechanism of the vitamin action etc. This book gives a complete insight of water soluble gums and resins that are used in day to day life in various Industries. It is an invaluable resource to all its readers, students, scientist, new entrepreneurs, existing industries and others.

Download or read book Chemistry for Pharmacy Students written by Lutfun Nahar and published by John Wiley & Sons. This book was released on 2019-08-26 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduces the key areas of chemistry required for all pharmacy degree courses and focuses on the properties and actions of drug molecules This new edition provides a clear and comprehensive overview of the various areas of general, organic, and natural products chemistry (in relation to drug molecules). Structured to enhance student understanding, it places great emphasis on the applications of key theoretical aspects of chemistry required by all pharmacy and pharmaceutical science students. This second edition particularly caters for the chemistry requirements in any ‘Integrated Pharmacy Curricula’, where science in general is meant to be taught ‘not in isolation’, but together with, and as a part of, other practice and clinical elements of the course. Chemistry for Pharmacy Students: General, Organic and Natural Product Chemistry, 2nd Edition is divided into eight chapters. It opens with an overview of the general aspects of chemistry and their importance to modern life, with emphasis on medicinal applications. The text then moves on to discuss the concepts of atomic structure and bonding and the fundamentals of stereochemistry and their significance to pharmacy in relation to drug action and toxicity. Various aspects of organic functional groups, organic reactions, heterocyclic chemistry, nucleic acids and their pharmaceutical importance are then covered in subsequent chapters, with the final chapter dealing with drug discovery and development, and natural product chemistry. Provides a student-friendly introduction to the main areas of chemistry required by pharmacy degree courses Written at a level suitable for non-chemistry students in pharmacy, but also relevant to those in life sciences, food science, and the health sciences Includes learning objectives at the beginning of each chapter Focuses on the physical properties and actions of drug molecules Chemistry for Pharmacy Students: General, Organic and Natural Product Chemistry, 2nd Edition is an essential book for pharmacy undergraduate students, and a helpful resource for those studying other subject areas within pharmaceutical sciences, biomedical sciences, cosmetic science, food sciences, and health and life sciences.

Download or read book Carbohydrate Chemistry written by J. S Brimacombe and published by Royal Society of Chemistry. This book was released on 1972-04 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbohydrate Chemistry provides review coverage of all publications relevant to the chemistry of monosaccharides and oligosaccharides in a given year. The amount of research in this field appearing in the organic chemical literature is increasing because of the enhanced importance of the subject, especially in areas of medicinal chemistry and biology. In no part of the field is this more apparent than in the synthesis of oligosaccharides required by scientists working in glycobiology. Clycomedicinal chemistry and its reliance on carbohydrate synthesis is now very well established, for example, by the preparation of specific carbohydrate- based antigens, especially cancer-specific oligosaccharides and glycoconjugates. Coverage of topics such as nucleosides, amino-sugars, alditols and cyclitols also covers much research of relevance to biological and medicinal chemistry. Each volume of the series brings together references to all published work in given areas of the subject and serves as a comprehensive database for the active research chemist Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.
