Spectroscopic studies of lipids and biological membranes
My first interest in nuclear magnetic resonance (n.m.r.) spectroscopy began in 1964, when it seemed to me that spectroscopy, and in particular n.m.r., would be a most desirable way to analyse unknowns without smelling everything, or heating with sodium and checking for hydrogen evolution with a match (the classical A-level approach at the time). Unfortunately, I had to wait a couple of years fo...

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
Studies on Lipids of Barracuda, Sphyraena pinguis
(1) The characteristics of the lipids (acetone-soluble lipid, lecithin, cephalin and sphingolipid) obtained from barracuda, Sphyraena pinguis GUNTHER, were studied from the view point of fat metabolism of fish. (2) Forty-one fresh sample fish caught in the Komekami fishing ground near Odawara City (west part of Kanagawa Prefecture, Japan) on the 4th of October, 1959, were extracted with acetone...
متن کاملThe Behavior of Biological Lipids
Lipids active in biological systems demonstrate a broad range of behavior in water, from hydrocarbons which are insoluble, to molecules such as bile salts that possess potent detergent properties and interact with water rather dynamically. The purpose of this paper is to describe some of the physical properties of lipids with respect to their inter— action with aqueous systems, and to classify ...
متن کاملStudies on Biological Oxidations
Pyruvic acid is one of the most reactive substances among those of importance in cellular metabolism. When carbohydrate is split during fermentation, pyruvic acid is the main end-product of the resulting series of phosphorylated oxidation-reductions. It thus becomes the immediate source for the formation of both lactic acid and alcohol. Pyruvic acid is decarboxylated by yeast; it may react with...
