Formaldehyde acts by?
OPTIONS
(A) Interaction with amino acids
(B) Oxidation process
(C) All of the above
(D) None of the above
ANSWER
(A) Interaction with amino acids
EXPLANATION
Formaldehyde is an aldehyde disinfectant that primarily acts by reacting with amino groups and other functional groups in proteins and nucleic acids, producing cross-linking and loss of biological function. Thus option A is correct; oxidation is not its principal mechanism, so option B and consequently option C are incorrect.
