Available in PDF, EPUB and Kindle. Book excerpt: The sodium of animal cell membranes converts the chemical energy obtained from the hydrolysis of adenosine 5' -triphosphate into a movement of the cations Na + and K + against an electrochemical gradient. The gradient is used subse quently as an energy source to drive the uptake of metabolic substrates in polar epithelial cells and to use it for purposes of communications in excitable cells. The biological importance of the sodium pump is evident from the fact that be tween 20-70% of the cell's metabolic energy is consumed for the pumping pro cess. Moreover, the sodium pump is an important biological system involved in regulatory processes like the maintenance of the cells' and organism's water me tabolism. It is therefore understandable that special cellular demands are han dled better by special isoforms of the sodium pump, that the expression of the sodium pump and their isoforms is regulated by hormones as is the activity of the sodium pump via hormone-regulated protein kinases. Additionally, the sodium pump itself seems to be a receptor for a putative new group of hormones, the endogenous digitalis-like substances, which still have to be defined in most cases in their structure. This group of substances has its chemically well known coun terpart in steroids from plant and toad origin which are generally known as "car diac glycosides". They are in medical use since at least 200 years in medicine in the treatment of heart diseases.

Download or read book The Discovery of the Cellular Sodium Pump in the 20th Century written by Beatrice Maier Anner and published by GRIN Verlag. This book was released on 2024-02-26 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2024 in the subject Chemistry - Bio-chemistry, , language: English, abstract: During her doctoral and postdoctoral studies, Beatrice Maier Anner became familiar with a fascinating biological system, called sodium pump by the physiologists and Na,K-ATPase by the biochemists; it is a sort of biomotor located in the cell membrane, which constantly expulses sodium (Na) ions from the cell interior and replaces them by potassium (K) ions, at the expense of chemical energy provided by adenosine-triphosphate (ATP) which is cleaved to adenosine-diphosphate (ADP) by the Na,K-ATPase, which gets its pump energy from the cleavage of this chemical bond. There would be no life without this fundamental biological system. Interestingly, it is also a pharmacological receptor, i.e. compounds extracted from the Digitalis plant of from the toad bind to the pump and block it, hence the toxicity of e.g. digitoxin or the toad's bufotoxins. The author has acquired extensive practical and theoretical knowledge of this biological system, acquired at the Baylor College of Medicine, Houston, TX, USA consisting in inserting purified functional Na,K-ATPase into artificial membranes (liposomes) in order to study the pump activity on a molecular level. The present book is a unique historical overview from the discovery and purification of the sodium pump to its reconstitution in artificial membranes in the 20th century. This short book permits to become rapidly familiar with this fascinating biomotor and to find unique historical sources.

Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2024 in the subject Chemistry - Bio-chemistry, language: English, abstract: The sodium pump, also called Na, K-ATPase (NKA) is a biomotor inserted in the membrane of all living cells; it extrudes sodium ions from the cell interior and replaces them with potassium ions. This is a fundamental and vital process. Furthermore, the sodium pump is also a receptor for pharmacological and toxicological compounds, such as the heart drug digitoxin and the arrow poison ouabain. Around 1974 it became possible to extract the sodium pump from the cell membrane and insert it into artificial phospholipid vesicles where it worked in the same way as in the cell. Now, the pump could be studied in its pure form on a molecular level. The author has been involved in this pioneering research and tells some fascinating stories concerning the first ultrastructural description of the reconstituted sodium pump in collaboration with specialists at Arhus University in Denmark and at Duke University in the US, and about the use of the reconstituted sodium pump for testing an unknown inhibitory compound in collaboration with Harvard Medical School.

Download or read book The Enzymes of Biological Membranes written by Anthony Martonosi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the information currently available on the transport systems of bacterial and animal cell membranes and their mode of coupling to metabolic supply of energy can be found in this volume. Consideration of the participating enzymes dictated the choice of topics: Several transport systems where little information is available on the enzymology of the process are not included, while separate chapters deal with y-glutamyl transpeptidase and intestinal disaccharidases which meet many of the requirements of transport enzymes. The volume also includes two chapters on photosynthetic membranes as a general introduction to the topic. Other aspects of biological transport and photosynthesis will be developed in detail in a forthcoming volume now in preparation. These chapters reveal the excitement and rapid advance of the field, the daily reports of new concepts, new techniques, and new experimental findings which instantly interact to generate further progress. Our aim was to provide a starting point for those who are just beginning, and an opportunity for others to stop, take stock, and start in a new direction. My warmest thanks to all who contributed to this volume.

Available in PDF, EPUB and Kindle. Book excerpt: The bicentenary of William Withering's now famous medical report entitled "An Account of the Foxglove and Some of its Medical Uses" has given us the occasion to analyze the state of the art. Cardiac glycosides in 1985 are considered tobe the basis for medical treatment of myocardial failure, together with diuretics and vasodilators in the more severe cases. Nevertheless, the controversy as to their exact place in the treatment of heart failure with sinus rhythm has never ceased. Although cardiac glycosides are of unquestionable value in tachycardia caused by atrial fibrillation or atrial flutter, the chronic use of these drugs in sinus rhythm is not generally accepted. The development of tolerance has been reported. It is of interest that Withering hirnself wrote: "-let it (foxglove) be continued until it either acts on the kidneys, the stomach, the pulse, or the bowels; Iet it be stopped upon the first appearance of any of these effects, and I will maintain that the patient will not suffer from its exhibition, nor the practitioner be disappointed in any reasonable expectation. " In West Germany alone, more than three million patients (about 5% of the total population) are constantly taking cardiac glycosides. These drugs are the most prescribed medicaments in many countries. Thus, we considered it worthwhile and necessary to review in a critical way today's knowledge about the foxglove; to report new findings and to evaluate old Statements.
