cofactor
cofactor
Noun
pl: cofactors
In biochemistry, this term describes a helper molecule that enables an enzyme to perform its catalytic function. It is often a metal ion or a small organic molecule, acting as a necessary chemical key that unlocks the enzyme's activity.
In statistics and clinical research, the term shifts to describe an extraneous variable. It represents a factor that might skew results if not accounted for, requiring researchers to isolate its effect to ensure the primary variable is the true cause of the observed outcome.
Meanings
