kinetic constant
[kɪˈnɛtɪk ˈkɑnstənt]
nounpl: kinetic constants
constante cinética
1. A numerical value in chemical kinetics that characterizes the rate of a chemical reaction, typically expressed as the rate constant (k) in rate equations
The kinetic constant for this reaction increases exponentially with temperature according to the Arrhenius equation.
A constante cinética para esta reação aumenta exponencialmente com a temperatura de acordo com a equação de Arrhenius.
2. A parameter used in enzyme kinetics to describe substrate binding affinity and catalytic efficiency, such as Km or Vmax
The Michaelis constant (Km) is an important kinetic constant that indicates enzyme-substrate affinity.
A constante de Michaelis (Km) é uma constante cinética importante que indica a afinidade enzima-substrato.
This is a technical scientific term used primarily in academic and research contexts in both Brazil and Portugal. The term is standardized across Portuguese-speaking scientific communities and is essential in chemistry, biochemistry, and pharmacology curricula. No colloquial variations exist.
