Basic Principles in Nucleic Acid Chemistry V2


Book Description

Basic Principles in Nuclear Acid Chemistry, Volume II presents the significant progress in nucleic acid research and its contribution and influence on various aspects of human life. This book contains five chapters and begins with the susceptibility of nucleic acids towards attack by chemical reagents whose reactions with polynucleotides have been studied. This topic is followed by a presentation of experimental techniques used to study the properties of nucleic acids. The following chapter discusses some basic features embodied in the polyribo- and poly-deoxyribonucleotide backbone chains; the possibility of rotation around backbone bonds in the ""random"" single-stranded form; and the short- and long-range interactions in idealized and real chains. This chapter also looks into the thermodynamic and polyelectrolyte aspects of nucleic acid behavior. A chapter describes the special features of the third class of DNA, namely, closed duplex DNA, in which covalent chain scissions are absent. The last chapter examines the intrinsic properties and the interaction of the dimers and oligomers, with special emphasis on the influence of the phosphodiester linkages on the conformation and interaction of these short segments of nucleic acids. This book is of great value to workers in biomedical research and to higher level biochemistry instructors.

A plasma chemistry study on global model for argon gas as a propellant to electrostatic gridded ion thruster


Book Description

Electric propulsion optimizes propellant mass and meets new propulsion device demands. These devices adjust satellite orbits and enable long missions. Among various thrusters, electrostatic ones have well-defined physics, simplifying operational parameter optimization. This study developed a global model for an Inductively Coupled Plasma (ICP) cylindrical ion thruster with an output polarized grid system. Argon propellant is injected into the chamber, and ICP plasma is generated by a radiofrequency current. Neutral and excited species are accelerated out by diffusion, while ionized species are accelerated via the polarized grids' electric field. The polarized grid system was optimized for better plasma sheath use. The model considers single and multi-step ionization, the Electron Energy Distribution Function (EEDF), neutral gas, and electron power balance equations. Excited species influence ionization energy, but not ionic density. However, the ion substitution rate increases, essential for thrust and specific impulse. The model determines the neutral gas temperature by considering the power balance and interactions with other species.




Fluorine in Heterocyclic Chemistry Volume 2


Book Description

This two-volume work combines comprehensive information on the chemistry of the fluorinated heterocycles. The material has been divided such that the first volume is dedicated to 5-membered fluorinated heterocycles and macrocycles, while the second volume combines data connected with the chemistry of fluorine containing 6-membered heterocycles. Both volumes will be of interest to synthetic organic chemists in general, and particularly for those colleagues working in the fields of heterocyclic-compound chemistry, materials chemistry, medicinal chemistry, and fluorine chemistry. All information is presented and classified clearly to be effective source for broad auditory of chemists. It will be interesting for scientists working in the field of inorganic and coordination chemistry. Fluorinated heterocycles are becoming increasingly important in many areas including the pharmaceutical industry, materials science and agriculture. The presence of fluorine can result in substantial functional changes in the biological as well as physicochemical properties of organic compounds. Incorporation of fluorine into drug molecules can greatly affect their physicochemical properties, such as bond strength, lipophilicity, bioavailability, conformation, electrostatic potential, dipole moment, pKa etc. as well as pharmacokinetic properties, such as tissue distribution, rate of metabolism and pharmacological properties, such as pharmacodynamics and toxicology.

Chemistry and Biochemistry of Flavoenzymes


Book Description

Chemistry and Biochemistry of Flavoenzymes summarizes the present knowledge of the chemical and physical properties of free flavin, modified flavins occurring in nature, and deazaflavin. This information forms the fundamental basis for understanding the catalytic properties of flavoenzymes. Flavoproteins involved in transport, electron transfer, oxidation, dehydrogenation and hydroxylation reactions are discussed with respect to their biochemical and biophysical properties. The book presents the catalytic mechanisms of the flavoproteins in detail and, where available, three-dimensional structures and molecular biology data are included. The medical aspects of free and protein-bound flavin are also briefly discussed. Chemistry and Biochemistry of Flavoenzymes is an essential reference source for chemists, biochemists, toxicologists, biologists, pharmacologists, and researchers in the pharmaceutical industry.
