  • Glutathionylspermidine is an intermediate formed in the biosynthesis of trypanothione, an essential metabolite in defence against chemical and oxi-dative stress in the Kinetoplastida. The kinetic mechanism for glutathionyl-spermidine synthetase (EC 6.3.1.8) from Crithidia fasciculata (CfGspS) obeys a rapid equilibrium random ter-ter model with kinetic constants KGSH= 609lm, KSpd= 157lmand KATP= 215lm.

  • Within the framework of the Walecka model (QHD-I)[1] the renormalized effective Dirac equation and the kinetic equation for fermion are presented. In fact, the fermion propagator in the medium is dramatically different from that in the vacuum. The main feature is the treating of the fermion distribution in non equilibrium, which depends on the interaction rate involving temperature.

  • We live in the age of biology—the human and many other organisms’ genomes have been sequenced and we are starting to understand the function of the metabolic machinery responsible for life on our planet. Thousands of new genes have been discovered, many of these coding for enzymes of yet unknown function. Understanding the kinetic behavior of an enzyme provides clues to its possible physiological role. From a biotechnological point of view, knowledge of the catalytic properties of an enzyme is required for the design of immobilized enzyme-based industrial processes.

  • This first part is concerned with processes in which the kinetic behaviour of a gaseous phase is rate-determining. The range of processes includes some which are carried out in vacuum systems in which Knudsen or free evaporation occurs from a condensed phase, to transport reactions where a chemical reaction occurs between a solid and the gaseous phase to produce molecular species containing some or all of the elements occurring in the solid phase.

  • enzymes are powerful biological catalysts that are essential for the proper maintenance and propagation of any organism. these properties make them excellent candidates as therapeutic targets to combat diseases of either genetic or pathogenic origin. in this regard, one goal of molecular medicine is to develop and implement effective agents that can modulate the activity of various enzymes involved in essential biological pathways. the process of developing and characterizing these small molecules, i.e., rational drug design, often requires a priori knowledge of the enzyme in question....

  • The Physical Chemistry In Brief offers a digest of all major formulas, terms and definitions needed for an understanding of the subject. They are illustrated by schematic figures, simple worked-out examples, and a short accompanying text. The concept of the book makes it different from common university or physical chemistry textbooks. In terms of contents, the Physical Chemistry In Brief embraces the fundamental course in physical chemistry as taught at the Institute of Chemical Technology, Prague, i.e.

  • This book is an introduction to the quantitative treatment of chemical reaction engineering. The level of the presentation is what we consider appropriate for a one-semester course. The text provides a balanced approach to the understanding of: (1) both homogeneous and heterogeneous reacting systems and (2) both chemical reaction engineering and chemical reactor engineering. We have emulated the teachings of Prof. Michel Boudart in numerous sections of this text.

  • From this Chapter we will study thermal properties of matter, that is what means the terms “hot” or “cold”, what is the difference between “heat” and “temparature”, and the laws relative to these concepts. We will know that the thermal phenomena are determined by internal motions of molecules inside a matter. There exists a form of energy which is called thermal energy, or “heat”, which is the total energy of all molecular motions, or internal energy.

  • Current Flow in an Electrochemical Cell: Thermodynamic arguments permit the feasibility of overall cell reactions to be predicted, but give no information on rates. To understand the latter it is necessary to consider the effects on various parts of the cell of forcing the cell voltage to assume a value different from that of the equilibrium potential Eeq (V) or electromotive force (emf). In the example of Figure 1, the cell contains hydrochloric acid as aqueous electrolyte and it divides into two compartments by a semipermeable membrane.
