Subject - Physical Chemistry Kinetic gas theory is a branch of physical chemistry that interprets the temperature and pressure of a gas as motion processes of molecular particles. For example, the translational energy Etrans of a mole of ideal gas depends on temperature or pressure: Etrans = NAεtrans = 32NAkT = 32RT = 32pVmNA = Avogadro constantεtrans = translational energy of a gas particlek = Boltzmann constantT = absolute temperatureR = general gas constantep = pressureVm = molar volume See also: mean free path, Maxwell-Boltzmann distributionLearning units in which the term is treatedMean free path of gas particles15 min.
Fig.1 Initially, specific minimal substrates of the HIV protease were searched for. It was found that heptapeptides are sufficient and are preferably split between the amino acids phenylalanine (Phe) and proline (Pro). Hydroxy compounds, which mimic the tetrahedral transition state that occurs in the cleavage mechanism, represented a first approach to the design of inhibitors.

Francium Francium occurs naturally only in the smallest traces as a member of the natural decay series of actinium, which in turn is the decay product of the isotope uranium-235. Among the previously known, without exception, radioactive francium isotopes, the most long-lived nuclide Fr223 has a half-life of approx.
Cytokine receptors Cytokines are messenger substances like hormones, i.e. they transmit information from cell to cell and act over a certain distance in the body, as they are transported in the bloodstream. However, due to the relatively short half-life of most cytokines, the range of these messenger substances is limited.
