The energy difference between the HOMO and LUMO is the HOMO–LUMO gap. Its size can be used to predict the strength and stability of transition metal complexes, as well as the colors they produce in solution. [1] As a rule of thumb, the smaller a compound's HOMO–LUMO gap, the more stable the compound.
The binding of the Ras GAP to the Rho GAP inhibits the activity of the Rho GAP, thereby activating the Rho G protein. [12] One GAP serves as a negative regulator of another GAP. The reasons for such cross-regulation across GAPs are yet unclear, but one possible hypothesis is that this cross-talk across GAPs attenuates the "off" signal of all ...
G. 1. phase. Mitosis in an animal cell (phases ordered counter-clockwise), with G 1 labeled at left. The G1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps ...

A November 2020 study by the West Health Policy Center stated that more than 1.1 million senior citizens in the U.S. Medicare program are expected to die prematurely over the next decade because they will be unable to afford their prescription medications, requiring an additional $17.7 billion to be spent annually on avoidable medical costs due ...
Lever rule. In chemistry, the lever rule is a formula used to determine the mole fraction ( xi) or the mass fraction ( wi) of each phase of a binary equilibrium phase diagram. It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.
A textbook is a book containing a comprehensive compilation of content in a branch of study with the intention of explaining it. Textbooks are produced to meet the needs of educators, usually at educational institutions. Schoolbooks are textbooks and other books used in schools. [1] [2] Today, many textbooks are published in both print and ...
Solution (chemistry) Making a saline water solution by dissolving table salt ( NaCl) in water. The salt is the solute and the water the solvent. In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
