A foreign key is a set of attributes in a table that refers to the primary key of another table, linking these two tables. In the context of relational databases, a foreign key is subject to an inclusion dependency constraint that the tuples consisting of the foreign key attributes in one relation, R, must also exist in some other (not necessarily distinct) relation, S; furthermore that those ...
The alloy Nb 10 Ni 9 Al 3 is the prototype for the M phase. It has orthorhombic space group with 52 atoms per unit cell. The alloy Cr 9 Mo 21 Ni 20 is the prototype for the P-phase. It has a primitive orthorhombic cell with 56 atoms. The alloy Co 5 Cr 2 Mo 3 is the prototype for the R-phase which belongs to the rhombohedral space group with 53 ...
Phosphofructokinase-1 (PFK-1) is one of the most important regulatory enzymes (EC 2.7.1.11) of glycolysis. It is an allosteric enzyme made of 4 subunits and controlled by many activators and inhibitors. PFK-1 catalyzes the important "committed" step of glycolysis, the conversion of fructose 6-phosphate and ATP to fructose 1,6-bisphosphate and ...
Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone. It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230, Novec 649, and FK-5-1-12. It is also known as ...
Protein kinase C inhibitors, such as ruboxistaurin, may potentially be beneficial in peripheral diabetic nephropathy. [26] Chelerythrine is a natural selective PKC inhibitor. Other naturally occurring PKCIs are miyabenol C, myricitrin, gossypol. Bryostatin 1 can act as a PKC inhibitor; It was investigated for cancer.
The difference between the two stability constants is mainly due to the difference in the standard entropy change, ΔS ⊖. In the reaction with the chelating ligand there are two particles on the left and one on the right, whereas in equation with the monodentate ligand there are three particles on the left and one on the right.
Fru-2,6-P 2 contributes to the rate-determining step of glycolysis as it activates enzyme phosphofructokinase 1 in the glycolysis pathway, and inhibits fructose-1,6-bisphosphatase 1 in gluconeogenesis. [1] Since Fru-2,6-P 2 differentially regulates glycolysis and gluconeogenesis, it can act as a key signal to switch between the opposing ...
f is the local Fanning friction factor (dimensionless); τ is the local shear stress (units of pascals (Pa) = kg/m 2, or pounds per square foot (psf) = lbm/ft 2); q is the bulk dynamic pressure (Pa or psf), given by: = ρ is the density of the fluid (kg/m 3 or lbm/ft 3) u is the bulk flow velocity (m/s or ft/s)
