Download and read online Plant Lectins in PDF and EPUB This volume surveys the chemistry, biochemistry, biosynthesis, metabolism and pharmacological properties of lectins. Lectins, which are most commonly found in plants, are widespread natural products with striking biological activities. Their specific ability to recognise and bind to simple or complex saccharides facilitates their role as effective information protein molecules. As agents of cell-to-cell recognition, lectins promote symbiosis between plants and specific nitrogen-fixing soil bacteria. As natural defensive molecules, they can protect plants against predators such as bacteria, fungi and insects. As part of our diet, lectins are powerful exogenous growth factors in the small intestine and influence our health, the digestive function and the bacterial ecology of the alimentary tract. Lectins are also important research tools in preparative biochemistry and cell science.
Download and read online Handbook of Plant Lectins in PDF and EPUB Plant lectins are extensively used as tools and as bioactive proteins in different areas of biomedical and biological research. The Handbook of Plant Lectins provides a comprehensive yet concise overview of the biochemical properties, carbohydrate-binding specificity, biological activities and applications of most of the currently known plant lectins. This handbook consists of two major sections: an introductory guide and a quick reference dictionary. Part I acquaints the newcomer to the lectin field with the essential information on lectins and their importance to biomedicine: * what are lectins? * their carbohydrate-binding specificity * effects on nutrition and immunology * use in histochemistry * application as therapeutic agents Part II lists approximately 200 lectin entries in alphabetical order. Each entry deals with the lectin(s) of a particular plant and provides, (where known), details of: * isolation and characterisation; * sugar binding specificity; * biological activities; * applications; * commercial availability; and, * a bibliography. Useful summary tables list lectins according to their specificity, thereby allowing the user to choose the best lectin for their application. A list of suppliers is also provided. Handbook of Plant Lectins will be of interest to biologists and biomedical researchers studying cell biology, cancer research, nutrition, immunology, pathology and physiology.
Download and read online Plant Glycobiology a sweet world of lectins glycoproteins glycolipids and glycans in PDF and EPUB Plants synthesize a wide variety of unique glycan structures which play essential roles during the life cycle of the plant. Being omnipresent throughout the plant kingdom, ranging from simple green algae to modern flowering plants, glycans contribute to many diverse processes. Glycans can function as structural components in the plant cell wall, assist in the folding of nascent proteins, act as signaling molecules in plant defense responses or (ER) stress pathways, or serve within the energy metabolism of a plant. In most cases, glycans are attached to other macromolecules to form so-called glycoconjugates (e.g. glycoproteins, proteoglycans and glycolipids), but they can also be present as free entities residing in the plant cell. Next to the broad, complex set of glycans, plants also evolved an elaborate collection of lectins or proteins with a lectin-like domain, which can recognize and bind to endogenous (plants-own) or exogenous (foreign) glycans. Though still poorly understood in plants, the dynamic interactions between lectins and carbohydrate structures are suggested to be involved in gene transcription, protein folding, protein transport, cell adhesion, signaling as well as defense responses. As such, a complex and largely undetermined glycan-interactome is established inside plant cells, between cells and their surrounding matrix, inside the extracellular matrix, and even between organisms. Studying the biological roles of plant glycans will enable to better understand plant development and physiology in order to fully exploit plants for food, feed and production of pharmaceutical proteins. In this Research Topic, we want to provide a platform for articles describing the latest research, perspectives and methodologies related to the fascinating world of plant glycobiology, with a focus on following subjects: 1. Identification and characterization of plant glycans, their biosynthetic and degradation enzymes 2. Characterization of plant lectins and glycoproteins 3. Plant glycans in the plant’s energy metabolism 4. Role of plant glycans in plant defense signaling 5. Use of plant lectins in pest control 6. Plant lectins as new tools in human medicine 7. Glyco-engineering in plants

Download and read online Lectins in PDF and EPUB A characteristic property of most, or perhaps all, proteins is their ability to combine specifically and reversibly with various substances. Well known examples are enzymes that bind substrates and inhibitors, and antibodies that bind antigens. This book deals with lectins, a class of proteins that bind carbohydrates. Another characteristic property of lectins is that they agglutinate cells or precipitate polysaccharides and glycoproteins. This is because lectins are polyvalent, i.e. each lectin molecule has at least two carbohydrate binding sites to allow crosslinking between cells (by combining with sugars on their surfaces) or between sugar containing macromolecules. The agglutinating and precipitating activities of lectins are very similar to those of antibodies. They can likewise be specifically inhibited by low molecular weight compounds (haptens), which in the case of lectins are sugars or sugar containing compounds (Fig. 1.1). Not surprisingly, therefore, many of the methods used in lectin research are based on immunochemical techniques. Nevertheless, lectins are different from antibodies in several important aspects. Many lectins are found in plants, microorganisms and viruses, which do not synthesize immunoglobulins. In fact, they are found in almost all living organisms (Table 1.1) and are not confined to specific organs or tissues. Another marked difference between the two classes of compound is that antibodies are structurally similar, whereas lectins are structurally diverse. In general, lectins are oligomeric proteins composed of subunits, usually with one sugar binding site per subunit.

Download and read online The Plant Paradox in PDF and EPUB “Dr. Gundry is a true trailblazer, always at the forefront of scientific knowledge. The Plant Paradox shows the world what pioneer thinking is about and is a must-read book for anyone interested in being as healthy as nature has designed them to be.” —Alejandro Junger MD, New York Times bestselling author of Clean, Clean Gut and Clean Eats “The Plant Paradox elegantly explains how plants defend themselves from being consumed by humans, and how eating the wrong ones at the wrong times immeasurably hurts our health. An eye-opening read.” —Mehmet Oz, MD, Professor of Surgery, New York Presbyterian/Columbia University Most of us have heard of gluten—a protein found in wheat that causes widespread inflammation in the body. Americans spend billions of dollars on gluten-free diets in an effort to protect their health. But what if we’ve been missing the root of the problem? In The Plant Paradox, renowned cardiologist Dr. Steven Gundry reveals that gluten is just one variety of a common, and highly toxic, plant-based protein called lectin. Lectins are found not only in grains like wheat but also in the “gluten-free” foods most of us commonly regard as healthy, including many fruits, vegetables, nuts, beans, and conventional dairy products. These proteins, which are found in the seeds, grains, skins, rinds, and leaves of plants, are designed by nature to protect them from predators (including humans). Once ingested, they incite a kind of chemical warfare in our bodies, causing inflammatory reactions that can lead to weight gain and serious health conditions. At his waitlist-only clinics in California, Dr. Gundry has successfully treated tens of thousands of patients suffering from autoimmune disorders, diabetes, leaky gut syndrome, heart disease, and neurodegenerative diseases with a protocol that detoxes the cells, repairs the gut, and nourishes the body. Now, in The Plant Paradox, he shares this clinically proven program with readers around the world. The simple (and daunting) fact is, lectins are everywhere. Thankfully, Dr. Gundry offers simple hacks we easily can employ to avoid them, including: Peel your veggies. Most of the lectins are contained in the skin and seeds of plants; simply peeling and de-seeding vegetables (like tomatoes and peppers) reduces their lectin content. Shop for fruit in season. Fruit contain fewer lectins when ripe, so eating apples, berries, and other lectin-containing fruits at the peak of ripeness helps minimize your lectin consumption. Swap your brown rice for white. Whole grains and seeds with hard outer coatings are designed by nature to cause digestive distress—and are full of lectins. With a full list of lectin-containing foods and simple substitutes for each, a step-by-step detox and eating plan, and delicious lectin-free recipes, The Plant Paradox illuminates the hidden dangers lurking in your salad bowl—and shows you how to eat whole foods in a whole new way.
Download and read online High Resolution Chromatography in PDF and EPUB The molecular biology revolution has required the development of new chromatographic techniques and the optimization of original techniques to give reasonable quantities of protein at high resolutions. The aim of this volume is to provide the necessary information in most experimental situations to enable rapid and effective purification. The first four chapters deal with the instrumental aspects of high resolution chromatography starting with the initial clean up steps prior to separation in chapter 1. Chapter 2 deals with microscale techniques, then chapter 3 describes the detector technologies that can determine information about the separated molecules. The final chapter in this section cover capillary electrophoresis and its associated techniques. The remaining chapters cover a range of chromatographic procedures based on the interaction of a specific ligand with its target protein or other macromolecule. Some chapters cover non-specific interactions using peptides, inhibitors, and antibodies as the affinity ligand while others focus on specific groups of molecules : oligosaccharides and glycosylated proteins, nucleotide-binding proteins, proteins binding free and chelated metal ions, and DNA binding proteins.
