[/wiːk ˈbaɪndɪŋ əˈfɪnɪti/]
nounpl: weak binding affinities
afinidade de ligação fraca
1. In biochemistry and molecular biology, the relatively low tendency or capacity of a ligand (molecule) to bind to a receptor or binding site, characterized by a higher dissociation constant (Kd) value
The drug exhibited weak binding affinity to the target protein, resulting in lower efficacy.
O medicamento apresentou afinidade de ligação fraca à proteína alvo, resultando em menor eficácia.
2. A condition where molecular interactions are transient and easily reversible, typically indicating less stable complex formation
Weak binding affinity often necessitates higher drug concentrations to achieve therapeutic effects.
A afinidade de ligação fraca geralmente requer concentrações mais elevadas de medicamento para alcançar efeitos terapêuticos.
This is a technical term primarily used in scientific, pharmaceutical, and medical research contexts. It is domain-specific and not part of everyday colloquial language in either Brazil or the USA. Understanding this concept is crucial for biochemists, pharmacologists, and drug developers working on molecular interactions and therapeutic efficacy.
