In cellular biology, stable cells are cells that multiply only when needed. They spend most of the time in the quiescent G 0 phase of the cell cycle but can be stimulated to enter the cell cycle when needed. Examples include the liver, the proximal tubules of the kidney and endocrine glands.
In chemistry, chemical stability is the thermodynamic stability of a chemical system, in particular a chemical compound or a polymer. [1] Colloquially, it may instead refer to kinetic persistence, the shelf-life of a metastable substance or system; that is, the timescale over which it begins to degrade.
Stable cell-cell interactions are required for cell adhesion within a tissue and controlling the shape and function of cells. [1] These stable interactions involve cell junctions which are multiprotein complexes that provide contact between neighboring cells. Cell junctions allow for the preservation and proper functioning of epithelial cell ...
The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. [2] The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ).
Coacervate droplets dispersed in a dilute phase. Coacervate (/ k oʊ ə ˈ s ɜːr v ə t / or / k oʊ ˈ æ s ər v eɪ t /) is an aqueous phase rich in macromolecules such as synthetic polymers, proteins or nucleic acids.
This is required, for instance, to protect the secretory cell from the activity of that protein. Apoenzymes become active enzymes on addition of a cofactor . Cofactors can be either inorganic (e.g., metal ions and iron-sulfur clusters ) or organic compounds, (e.g., [Flavin group|flavin] and heme ).
In coordination chemistry, a stability constant (also called formation constant or binding constant) is an equilibrium constant for the formation of a complex in solution. It is a measure of the strength of the interaction between the reagents that come together to form the complex. There are two main kinds of complex: compounds formed by the ...
In chemistry, a steady state is a situation in which all state variables are constant in spite of ongoing processes that strive to change them. For an entire system to be at steady state, i.e. for all state variables of a system to be constant, there must be a flow through the system (compare mass balance). A simple example of such a system is ...
